{{Short description|Subfield of linguistic semantics}}
'''Lexical semantics''' (also known as '''lexicosemantics'''), as a subfield of [[linguistics|linguistic]] [[semantics]], is the study of word meanings.<ref name="Pustejovsky2005">Pustejovsky, J. (2005) ''[https://books.google.com/books?id=cxYGQfiD_1oC&pg=PT11380 Lexical Semantics: Overview]'' in Encyclopedia of Language and Linguistics, second edition, Volumes 1-14</ref><ref name="Taylor2017">Taylor, J.

The units of analysis in lexical semantics are lexical units which include not only words but also sub-words or sub-units such as [[affix]]es and even [[compound word]]s and [[phrase]]s. Lexical units include the catalogue of words in a language, the [[lexicon]]. Lexical semantics looks at how the meaning of the lexical units correlates with the structure of the language or [[syntax]]. This is referred to as [[syntax-semantics interface]].<ref>{{cite book|last1=Pustejovsky|first1=James|title=The Generative Lexicon|date=1995|publisher=MIT Press|url=https://books.google.com/books?id=p2GJBNpBVg4C&q=%22lexical+semantics%22|isbn=9780262661409}}</ref>

The study of lexical semantics concerns:
* the classification and decomposition of lexical items
* the differences and similarities in lexical semantic structure cross-linguistically
* the relationship of lexical meaning to [[Sentence (linguistics)|sentence]] meaning and [[syntax]].

Lexical units, also referred to as syntactic atoms, can be independent such as in the case of root words or parts of compound words or they require association with other units, as prefixes and suffixes do. The former are termed [[free morpheme]]s and the latter [[bound morpheme]]s.<ref>{{cite book|last1=Di Sciullo|first1=Anne-Marie|last2=Williams|first2=Edwin|title=On the definition of word|url=https://archive.org/details/ondefinitionofwo00disc|url-access=registration|date=1987|publisher=MIT press|location=Cambridge, MA}}</ref> They fall into a narrow range of meanings ([[semantic field]]s) and can combine with each other to generate new denotations.

[[Cognitive semantics]] is the linguistic paradigm/framework that since the 1980s has generated the most studies in lexical semantics, introducing innovations like [[prototype theory]], [[conceptual metaphor]]s, and [[Frame semantics (linguistics)|frame semantics]].<ref>Geeraerts, Dirk (2010) ''[https://books.google.com/books?id=JC8TDAAAQBAJ Introduction]'', p. xiv, in Theories of Lexical Semantics</ref>

== Lexical relations ==

Lexical items contain information about category (lexical and syntactic), form and meaning. The semantics related to these categories then relate to each lexical item in the [[lexicon]].<ref name="Glossary" /> Lexical items can also be semantically classified based on whether their meanings are derived from single lexical units or from their surrounding environment.

Lexical items participate in regular patterns of association with each other. Some relations between lexical items include [[Hyponymy and hypernymy|hyponymy, hypernymy]], [[synonym]]y, and [[antonym]]y, as well as [[homonym]]y.<ref name="Glossary">{{cite web|last1=Loos|first1=Eugene|last2=Anderson|first2=Susan|last3=H. Day, Jr.|first3=Dwight|last4=Jordan|first4=Paul|last5=Wingate|first5=J. Douglas|title=What is a lexical relation?|url=http://www-01.sil.org/linguistics/GlossaryOfLinguisticTerms/WhatIsALexicalRelation.htm|website=Glossary of linguistic terms|publisher=LinguaLinks}}</ref>

=== Hyponymy and hypernymy ===
[[Hyponymy and hypernymy]] refer to a relationship between a general term and the more specific terms that fall under the category of the general term.

For example, the colors ''red'', ''green'', ''blue'' and ''yellow'' are hyponyms. They fall under the general term of ''color'', which is the hypernym.
[[File:Colortaxonomy.png|thumb|Taxonomy showing the hypernym "color"]]
{|
|-
| 
 ''Color (hypernym) → red, green, yellow, blue (hyponyms)''
|}

Hyponyms and hypernyms can be described by using a [[Taxonomy (general)|taxonomy]], as seen in the example.

=== Synonym ===
[[Synonym]] refers to words that are pronounced and spelled differently but contain the same meaning.
{|
|-
|  
 ''Happy, joyful, glad''<ref name="Glossary" />
|}

=== Antonym ===
[[Antonym]] refers to words that are related by having the opposite meanings to each other.
There are three types of antonyms: [[Opposite (semantics)#Gradable antonyms|graded antonyms]], [[Opposite (semantics)#Complementary antonyms|complementary antonyms]], and [[Converse (semantics)|relational antonyms]].
{|
|-
|  
 ''Sleep, awake''<ref name="Glossary" />
 ''long, short''
|}

=== Homonymy ===
[[Homonymy]] refers to the relationship between words that are spelled or pronounced the same way but hold different meanings.
{|
|-
|  
 ''bank (of river)''
 ''bank (financial institution)''
|}

=== Polysemy ===
[[Polysemy]] refers to a word having two or more related meanings.
{|
|
 ''bright (shining)''
 ''bright (intelligent)''
|}
[[File:Semantic Net.svg|thumb|An example of a semantic network]]

=== Semantic networks ===
Lexical semantics also explores whether the meaning of a lexical unit is established by looking at its neighbourhood in the [[semantic network]],<ref>{{cite book |last1=Segev |first1=Elad |title=Semantic Network Analysis in Social Sciences |date=2022 |publisher=Routledge |location=London |isbn=9780367636524 |url=https://www.routledge.com/Semantic-Network-Analysis-in-Social-Sciences/Segev/p/book/9780367636524 |access-date=5 December 2021 |archive-date=5 December 2021 |archive-url=https://web.archive.org/web/20211205140726/https://www.routledge.com/Semantic-Network-Analysis-in-Social-Sciences/Segev/p/book/9780367636524 |url-status=live }}</ref>  (words it occurs with in natural sentences), or whether the meaning is already locally contained in the lexical unit.

In English, [[WordNet]] is an example of a semantic network. It contains English words that are grouped into [[Synonym Ring|synsets]]. Some semantic relations between these synsets are [[meronymy]], [[hyponymy]], [[synonymy]], and [[antonymy]].

== Semantic fields ==

=== How lexical items map onto concepts ===
First proposed by Trier in the 1930s,<ref name=famer1999>Famer, Pamela B.; Mairal Usón, Ricardo (1999). "Constructing a Lexicon of English Verbs". Functional Grammar (in English) 23 (illustrated ed.). Walter de Gruyter. p. 350. {{ISBN|9783110164169}}.</ref> [[semantic field]] theory proposes that a group of words with interrelated meanings can be categorized under a larger conceptual domain. This entire entity is thereby known as a semantic field. The words ''boil'', ''bake'', ''fry'', and ''roast'', for example, would fall under the larger semantic category of ''cooking''. Semantic field theory asserts that lexical meaning cannot be fully understood by looking at a word in isolation, but by looking at a group of semantically related words.<ref>{{cite book|first=Adrienne|last=Lehrer|title=Historical Semantics, Historical Word Formation|chapter=The influence of semantic fields on semantic change|publisher=Walter de Gruyter|date=1985|pages=283–296 |chapter-url=http://alehrer.faculty.arizona.edu/sites/alehrer.faculty.arizona.edu/files/Semantic%20fields%20and%20change.pdf}}</ref> Semantic relations can refer to any relationship in meaning between [[lexeme]]s, including synonymy ''(big'' and ''large),'' antonymy ''(big'' and ''small),'' hypernymy and hyponymy ''(rose'' and ''flower),'' converseness ''(buy'' and ''sell),'' and incompatibility. Semantic field theory does not have concrete guidelines that determine the extent of semantic relations between lexemes. The abstract validity of the theory is a subject of debate.<ref name=famer1999 />

Knowing the meaning of a lexical item therefore means knowing the semantic entailments the word brings with it. However, it is also possible to understand only one word of a semantic field without understanding other related words. Take, for example, a taxonomy of plants and animals: it is possible to understand the words ''rose'' and ''rabbit'' without knowing what a ''marigold'' or a ''muskrat'' is. This is applicable to colors as well, such as understanding the word ''red'' without knowing the meaning of ''scarlet,'' but understanding ''scarlet'' without knowing the meaning of ''red'' may be less likely. A semantic field can thus be very large or very small, depending on the level of contrast being made between lexical items. While cat and dog both fall under the larger semantic field of animal, including the breed of dog, like ''German shepherd,'' would require contrasts between other breeds of dog (e.g. ''corgi'', or ''poodle''), thus expanding the semantic field further.<ref>{{cite book

Verbs can belong to one of three types: states, processes, or transitions.
{|
|-
| 
 ''(1) a. The door is '''closed'''.''<ref name=Pustejovsky />
 ''    b. The door '''closed'''.''
 ''    c. John '''closed''' the door.''
|}
(1a) defines the state of the door being closed; there is no opposition in this [[Predicate (grammar)|predicate]]. (1b) and (1c) both have predicates showing transitions of the door going from being implicitly ''open'' to ''closed''. (1b) gives the [[Intransitive verb|intransitive]] use of the verb close, with no explicit mention of the causer, but (1c) makes explicit mention of the [[Agent (grammar)|agent]] involved in the action.

== Syntactic basis of event structure: a brief history ==

=== Generative semantics in the 1960s ===
The analysis of these different lexical units had a decisive role in the field of "[[generative linguistics]]" during the 1960s.<ref name="WILEY Blackwell">{{cite book|last1=Sportiche|first1=Dominique|last2=Koopman|first2=Hilda|last3=Stabler|first3=Edward|title=An Introduction to Syntactic Analysis and Theory|date=2014|publisher=WILEY Blackwell}}</ref> The term ''generative'' was proposed by Noam Chomsky in his book [[Syntactic Structures]] published in 1957. The term ''generative linguistics'' was based on Chomsky's [[generative grammar]], a linguistic theory that states systematic sets of rules ([[X' theory]])  can predict grammatical phrases within a natural language.<ref>{{cite book|last1=Chomsky|first1=Noam|title=Syntactic Structures|date=1957|publisher=Mouton de Gruyter}}</ref> Generative Linguistics is also known as Government-Binding Theory.
Generative linguists of the 1960s, including [[Noam Chomsky]] and [[Ernst von Glasersfeld]], believed semantic relations between [[transitive verbs]] and [[intransitive verbs]] were tied to their independent syntactic organization.<ref name="WILEY Blackwell"/> This meant that they saw a simple verb phrase as encompassing a more complex syntactic structure.<ref name="WILEY Blackwell"/>

=== Lexicalist theories in the 1980s ===
Lexicalist theories became popular during the 1980s, and emphasized that a word's internal structure was a question of [[morphology (linguistics)|morphology]] and not of [[syntax]].<ref name=ReferenceA>{{cite journal|last1=Scalise|first1=Sergio|last2=Guevara|first2=Emiliano|title=The Lexicalist Approach to Word-Formation|date=1985}}</ref> Lexicalist theories emphasized that complex words (resulting from compounding and derivation of [[affixes]]) have lexical entries that are derived from morphology, rather than resulting from overlapping syntactic and phonological properties, as Generative Linguistics predicts. The distinction between Generative Linguistics and Lexicalist theories can be illustrated by considering the transformation of the word ''destroy'' to ''destruction'':

* '''Generative Linguistics theory''': states the transformation of ''destroy'' → ''destruction'' as the nominal, ''nom'' + ''destroy,'' combined with [[phonological rule]]s that produce the output ''destruction''. Views this transformation as independent of the morphology.
* '''Lexicalist theory''': sees ''destroy'' and ''destruction'' as having idiosyncratic lexical entries based on their differences in morphology. Argues that each morpheme contributes specific meaning. States that the formation of the complex word ''destruction'' is accounted for by a set of ''Lexical Rules,'' which are different and independent from syntactic rules.<ref name="ReferenceA"/>

A [[lexical entry]] lists the basic properties of either the whole word, or the individual properties of the morphemes that make up the word itself. The properties of [[lexical item]]s include their category selection ''c-selection'', selectional properties ''s-selection'', (also known as semantic selection),<ref name="WILEY Blackwell"/> phonological properties, and features. The properties of lexical items are idiosyncratic, unpredictable, and contain specific information about the lexical items that they describe.<ref name="WILEY Blackwell"/>

The following is an example of a lexical entry for the verb ''put'':
{|
|-
| 
 ''put:'' V DP<sub>''agent''</sub> DP<sub>''experiencer''</sub>/PP<sub>''locative''</sub>
|}

Lexicalist theories state that a word's meaning is derived from its morphology or a speaker's lexicon, and not its syntax. The degree of morphology's influence on overall grammar remains controversial.<ref name="WILEY Blackwell"/> Currently, the linguists that perceive one engine driving both morphological items and syntactic items are in the majority.

=== Micro-syntactic theories: 1990s to the present ===
By the early 1990s, Chomsky's [[Minimalist program|minimalist framework]] on language structure led to sophisticated probing techniques for investigating languages.<ref>{{cite journal|last1=Fodor|first1=Jerry|last2=Lepore|first2=Ernie|date=Aug 1999|journal=The Journal of Philosophy|volume=96|issue=8|pages=381–403|jstor=2564628|doi=10.5840/jphil199996818|title=All at Sea in Semantic Space|s2cid=14948287}}</ref> These probing techniques analyzed negative data over [[prescriptive grammar]]s, and because of Chomsky's proposed Extended Projection Principle in 1986, probing techniques showed where specifiers of a sentence had moved to in order to fulfill the EPP. This allowed syntacticians to hypothesize that lexical items with complex syntactic features (such as [[Ditransitive verb|ditransitive]], [[inchoative verb|inchoative]], and [[causative verb|causative]] verbs), could select their own specifier element within a [[Concrete syntax tree|syntax tree]] construction. (For more on probing techniques, see Suci, G., Gammon, P., & Gamlin, P. (1979)).

This brought the focus back on the [[syntax-lexical semantics interface]]; however, syntacticians still sought to understand the relationship between complex verbs and their related syntactic structure, and to what degree the syntax was projected from the lexicon, as the Lexicalist theories argued.

In the mid 1990s, linguists [[Heidi Harley]], [[Samuel Jay Keyser]], and [[Kenneth L. Hale|Kenneth Hale]] addressed some of the implications posed by complex verbs and a lexically-derived syntax. Their proposals indicated that the predicates CAUSE and BECOME, referred to as subunits within a Verb Phrase, acted as a lexical semantic template.<ref>Pinker, S. 1989. "Learnability and Cognition: The Acquisition of Argument Structure." Cambridge. MIT Press. pp 89</ref> ''Predicates'' are verbs and state or affirm something about the subject of the sentence or the argument of the sentence. For example, the predicates ''went'' and ''is here'' below affirm the argument of the subject and the state of the subject respectively.

{|

| 
 ''Lucy went home.''
 ''The parcel is here.''
|}

The subunits of Verb Phrases led to the Argument Structure Hypothesis and Verb Phrase Hypothesis, both outlined below.<ref>Harley, Heidi. "Events, agents and the interpretation of VP-shells." (1996).</ref> The recursion found under the "umbrella" Verb Phrase, the VP Shell, accommodated binary-branching theory; another critical topic during the 1990s.<ref>Kayne, Richard S. The antisymmetry of syntax. No. 25. MIT Press, 1994.</ref> Current theory recognizes the predicate in Specifier position of a tree in inchoative/[[Anticausative verb|anticausative]] verbs (intransitive), or causative verbs (transitive) is what selects the [[theta role]] conjoined with a particular verb.<ref name="WILEY Blackwell"/>

==== Hale & Keyser 1990 ====
[[File:SyntacticTreeputHaleandKeyser.png|thumb|Hale and Keyser 1990 structure]]
[[Kenneth L. Hale|Kenneth Hale]] and [[Samuel Jay Keyser]] introduced their thesis on lexical argument structure during the early 1990s.<ref name="Hale">{{cite journal|last1=Hale|first1=Kenneth|last2=Keyser|first2=Samuel Jay|title=On Argument Structures and the Lexical expression of syntactic relations|journal=Essays in Linguistics in Honor of Sylvain Bromberger|date=1993}}</ref>
They argue that a predicate's argument structure is represented in the syntax, and that the syntactic representation of the predicate is a lexical projection of its arguments. Thus, the structure of a predicate is strictly a lexical representation, where each phrasal head projects its argument onto a phrasal level within the syntax tree. The selection of this phrasal head is based on Chomsky's Empty Category Principle. This lexical projection of the predicate's argument onto the syntactic structure is the foundation for the Argument Structure Hypothesis.<ref name="Hale" /> This idea coincides with Chomsky's [[Projection Principle]], because it forces a VP to be selected locally and be selected by a Tense Phrase (TP).

Based on the interaction between lexical properties, locality, and the properties of the EPP (where a phrasal head selects another phrasal element locally), Hale and Keyser make the claim that the Specifier position or a complement are the only two semantic relations that project a predicate's argument. In 2003, Hale and Keyser put forward this hypothesis and argued that a lexical unit must have one or the other, Specifier or Complement, but cannot have both.<ref>Paul Bennett, 2003.

==== Halle & Marantz 1993 ====
{{main article|Distributed morphology}}
[[File:Distributedmorphtree.png|thumbnail|Halle & Marantz 1993 structure]]
[[Morris Halle]] and [[Alec Marantz]] introduced the notion of [[distributed morphology]] in 1993.<ref>Halle, Morris; Marantz, Alec (1993), Distributed Morphology and the Pieces of Inflection, The View from Building 20 (Cambridge, MA: MIT Press): 111–176</ref> This theory views the syntactic structure of words as a result of morphology and semantics, instead of the morpho-semantic interface being predicted by the syntax. Essentially, the idea that under the Extended Projection Principle there is a local boundary under which a special meaning occurs. This meaning can only occur if a head-projecting morpheme is present within the local domain of the syntactic structure.<ref name="Marantz">Marantz, Alec. 1997.  '[https://repository.upenn.edu/cgi/viewcontent.cgi?article=1795&context=pwpl No escape from syntax: Don't try morphological analysis in the privacy of your own Lexicon].' Proceedings of the 21st Annual Penn Linguistics Colloquium:  Penn Working Papers in Linguistics</ref> The following is an example of the tree structure proposed by distributed morphology for the sentence ''"John's destroying the city"''. ''Destroy'' is the root, V-1 represents verbalization, and D represents nominalization.<ref name="Marantz" />

==== Ramchand 2008 ====
In her 2008 book, ''Verb Meaning and The Lexicon: A First-Phase Syntax'', linguist [[Gillian Ramchand]] acknowledges the roles of lexical entries in the selection of complex verbs and their arguments.<ref name="Ramchand" /> 'First-Phase' syntax proposes that event structure and event participants are directly represented in the syntax by means of [[Branching (linguistics)|binary branching]]. This branching ensures that the Specifier is the consistently subject, even when investigating the projection of a complex verb's lexical entry and its corresponding syntactic construction. This generalization is also present in Ramchand's theory that the complement of a head for a complex verb phrase must co-describe the verb's event.

Ramchand also introduced the concept of Homomorphic Unity, which refers to the structural synchronization between the head of a complex verb phrase and its complement. According to Ramchand, Homomorphic Unity is "when two event descriptors are syntactically Merged, the structure of the complement must unify with the structure of the head."<ref name=Ramchand>{{cite book|last1=Ramchand|first1=Gillian|title=Verb Meaning and the Lexicon: A First Phase Syntax|date=2008|publisher=Cambridge University Press|isbn=9780511486319}}</ref>

== Classification of event types ==

=== Intransitive verbs: unaccusative versus unergative ===

}}

The unaccusative hypothesis was put forward by David Perlmutter in 1987, and describes how two classes of intransitive verbs have two different syntactic structures. These are [[unaccusative verb]]s and [[unergative verb]]s.<ref name="Lappin">Lappin, S. (Ed.). (1996). Handbook of contemporary semantic theory. Oxford, UK: Blackwell Publishers.</ref> These classes of verbs are defined by Perlmutter only in syntactic terms. They have the following structures underlyingly:

* unaccusative verb: __ [<sub>VP</sub> V NP]<ref name="Lappin" />
* unergative verb: NP [<sub>VP</sub> V]

The following is an example from English:

{|
|-
|  
 (2) '''Unaccusative'''
     a. ''Mary fell.''<ref>Loporcaro, M. (2003). The Unaccusative Hypothesis and participial absolutes in Italian: Perlmutter’s generalization revised. Rivista di Linguistica/Italian Journal of Linguistics, 15, 199-263.</ref>
     '''Unergative'''
     b. ''Mary worked.''
|}

In (2a) the verb underlyingly takes a direct object, while in (2b) the verb underlyingly takes a subject.

=== Transitivity alternations: the inchoative/causative alternation ===
{{main article|Causative alternation}}
The change-of-state property of Verb Phrases (VP) is a significant observation for the syntax of lexical semantics because it provides evidence that subunits are embedded in the VP structure, and that the meaning of the entire VP is influenced by this internal grammatical structure. (For example, the VP ''the vase broke'' carries a change-of-state meaning of the vase becoming broken, and thus has a silent BECOME subunit within its underlying structure.) There are two types of change-of-state predicates: [[inchoative]] and [[causative]].

Inchoative verbs are [[Intransitive verb|intransitive]], meaning that they occur without a direct object, and these verbs express that their subject has undergone a certain change of state. Inchoative verbs are also known as [[anticausative]] verbs.<ref name="An Overview of Lexical Semantics">{{cite journal|last1=Johnson|first1=Kent|title=An Overview of Lexical Semantics|journal=Philosophy Compass|date=2008|volume=3 |pages=119–134|doi=10.1111/j.1747-9991.2007.00101.x |url=http://www.lps.uci.edu/~johnsonk/Publications/Johnson.AnOverviewOfLexicalSemantics.pdf}}</ref> Causative verbs are transitive, meaning that they occur with a direct object, and they express that the subject causes a change of state in the object.

Linguist [[Martin Haspelmath]] classifies inchoative/causative verb pairs under three main categories: causative, anticausative, and non-directed alternations.<ref name="Haspelmath1">{{cite book|last1=Haspelmath|first1=Martin|title=Causatives and transitivity, edited by Bernard Comrie & Maria Polinsky|chapter=More on the typology of inchoative/causative verb alternations|journal=Causatives and Transitivity|date=1993|volume=23|pages=87–121|chapter-url=https://www.academia.edu/3452966|doi=10.1075/slcs.23.05has|series=Studies in Language Companion Series|publisher=Benjamins|isbn=978-90-272-3026-3|url=https://zenodo.org/record/227093}}</ref> Non-directed alternations are further subdivided into labile, equipollent, and suppletive alternations.

}}
[[English language|English]] tends to favour [[Ambitransitive verb|labile alternations]],<ref>{{cite journal|last1=Piñón|first1=Christopher|title=A finer look at the causative-inchoative alternation|date=2001|pages=346–364|url=http://elanguage.net/journals/salt/article/viewFile/11.346/1719}}</ref> meaning that the same verb is used in the inchoative and causative forms.<ref name="Haspelmath1" /> This can be seen in the following example: ''broke'' is an intransitive inchoative verb in (3a) and a transitive causative verb in (3b).
{|
|-
| 
 (3) '''English'''<ref name="An Overview of Lexical Semantics" />
     a. ''The vase '''broke'''.''
     b. ''John '''broke''' the vase''.
|}
As seen in the underlying tree structure for (3a), the silent subunit BECOME is embedded within the Verb Phrase (VP), resulting in the inchoative change-of-state meaning (y become z). In the underlying tree structure for (3b), the silent subunits CAUS and BECOME are both embedded within the VP, resulting in the causative change-of-state meaning (x cause y become z).<ref name="WILEY Blackwell" />

English change of state verbs are often de-adjectival, meaning that they are derived from adjectives. We can see this in the following example:
{|
|-
| 
 (4) a. ''The knot is loose.''<ref>{{cite journal | last1 = Tham | first1 = S | year = 2013 | title = Change of state verbs and result state adjectives in Mandarin Chinese | journal = Journal of Linguistics | volume = 49 | issue = 3| pages = 647–701 | doi=10.1017/s0022226713000261}}</ref>
     b. ''The knot loosened.''
     c. ''Sandy loosened the knot.''
|}
In example (4a) we start with a stative intransitive adjective, and derive (4b) where we see an intransitive inchoative verb. In (4c) we see a transitive causative verb.

==== Marked inchoatives ====
Some languages (e.g., [[German language|German]], [[Italian language|Italian]], and [[French language|French]]), have multiple morphological classes of inchoative verbs.<ref name="Schafer">{{cite book|last1=Schafer|first1=Florian|title=The Syntax of (Anti-)Causatives|publisher=John Benjamins Publishing Company|isbn=9789027255099|page=1|year=2008}}</ref> Generally speaking, these languages separate their inchoative verbs into three classes: verbs that are obligatorily unmarked (they are not marked with a [[reflexive pronoun]], [[clitic]], or [[affix]]), verbs that are optionally marked, and verbs that are obligatorily marked. The causative verbs in these languages remain unmarked. [[Martin Haspelmath|Haspelmath]] refers to this as the [[anticausative]] alternation.
{{multiple image

| image1 = Zerbrach.png
|thumb
| caption1 = Underlying tree structure for (4a)

| image2 = Hanszerbrach.png
|thumb
| caption2 = Underlying tree structure for (4b)

}}
For example, inchoative verbs in [[German language|German]] are classified into three morphological classes. ''Class A'' verbs necessarily form inchoatives with the reflexive pronoun ''{{lang|de|sich}}'', ''Class B'' verbs form inchoatives necessarily without the reflexive pronoun, and ''Class C'' verbs form inchoatives optionally with or without the reflexive pronoun. In example (5), the verb ''{{lang|de|zerbrach}}'' is an unmarked inchoative verb from ''Class B'', which also remains unmarked in its causative form.<ref name="Schafer" />

In contrast, the verb ''öffnete'' is a ''Class A'' verb which necessarily takes the reflexive pronoun ''sich'' in its inchoative form, but remains unmarked in its causative form.

There has been some debate as to whether the different classes of inchoative verbs are purely based in morphology, or whether the differentiation is derived from the lexical-semantic properties of each individual verb. While this debate is still unresolved in languages such as [[Italian language|Italian]], [[French language|French]], and [[Greek language|Greek]], it has been suggested by linguist Florian Schäfer that there are semantic differences between marked and unmarked inchoatives in [[German language|German]]. Specifically, that only unmarked inchoative verbs allow an unintentional causer reading (meaning that they can take on an "''x unintentionally caused y''" reading).<ref name="Schafer" />

==== Marked causatives ====

Causative morphemes are present in the verbs of many languages (e.g., [[Tagalog language|Tagalog]], [[Malagasy language|Malagasy]], [[Turkish language|Turkish]], etc.), usually appearing in the form of an affix on the verb.<ref name="An Overview of Lexical Semantics" /> This can be seen in the following examples from [[Tagalog language|Tagalog]], where the causative prefix ''pag-'' (realized here as ''nag'') attaches to the verb ''tumba'' to derive a causative transitive verb in (7b), but the prefix does not appear in the inchoative intransitive verb in (7a). [[Martin Haspelmath|Haspelmath]] refers to this as the [[causative]] alternation.

=== Ditransitive verbs ===

Richard Kayne proposed the idea of unambiguous paths as an alternative to c-commanding relationships, which is the type of structure seen in examples (8). The idea of unambiguous paths stated that an antecedent and an anaphor should be connected via an unambiguous path. This means that the line connecting an antecedent and an anaphor cannot be broken by another argument.<ref name="Kayne">Kayne, R. (1981). Unambiguous paths. In R. May & F. Koster (Eds.), Levels of syntactic representation (143-184). Cinnaminson, NJ: Foris Publications.</ref> When applied to ditransitive verbs, this hypothesis introduces the structure in diagram (8a). In this tree structure it can be seen that the same path can be traced from either DP to the verb. Tree diagram (7b) illustrates this structure with an example from English. This analysis was a step toward binary branching trees, which was a theoretical change that was furthered by Larson's VP-shell analysis.<ref name="Larson" />

==== Larson's 1988 "VP-shell" analysis ====

Larson posited his Single Complement Hypothesis in which he stated that every complement is introduced with one verb. The Double Object Construction presented in 1988 gave clear evidence of a hierarchical structure using asymmetrical binary branching.<ref name=Larson>{{cite journal|last1=Larson|first1=Richard|title=On the Double Object Construction|journal=Linguistic Inquiry|date=1988|volume=19|issue=3|pages=589–632|jstor=25164901}}</ref> Sentences with double objects occur with ditransitive verbs, as we can see in the following example:
[[File:Vpshelltree.png|thumb|Larson's proposed binary-branching VP-shell structure for (9)]]
{|
|
| 
 (9) a. ''John sent Mary a package.''<ref>{{cite journal|last1=Miyagawa|first1=Shigeru|last2=Tsujioka|first2=Takae|title=Argument Structure and Ditransitive Verbs in Japanese|journal=Journal of East Asian Linguistics|date=2004|volume=13|issue=1|pages=1–38|doi=10.1023/b:jeal.0000007345.64336.84|citeseerx=10.1.1.207.6553|s2cid=122993837}}</ref>
     b. ''John sent a package to Mary.''
|}
It appears as if the verb ''send'' has two objects, or complements (arguments): both ''Mary'', the recipient and ''parcel'', the theme. The argument structure of ditransitive verb phrases is complex and has undergone different structural hypothesis.

The original structural hypothesis was that of ternary branching seen in (9a) and (9b), but following from Kayne's 1981 analysis, Larson maintained that each complement is introduced by a verb.<ref name="Kayne" /><ref name="Larson" />

Their hypothesis shows that there is a lower verb embedded within a VP shell that combines with an upper verb (can be invisible), thus creating a VP shell (as seen in the tree diagram to the right). Most current theories no longer allow the ternary tree structure of (9a) and (9b), so the theme and the goal/recipient are seen in a hierarchical relationship within a [[Branching (linguistics)#Binary vs. n-ary branching|binary branching]] structure.<ref name="Bruening">{{cite journal|last1=Bruening|first1=Benjamin|title=Ditransitive Asymmetries and a Theory of Idiom Formation|journal=Linguistic Inquiry|date=November 2010|volume=41|issue=4|pages=519–562|doi=10.1162/LING_a_00012|s2cid=57567192}}</ref>

Following are examples of Larson's tests to show that the hierarchical (superior) order of any two objects aligns with a linear order, so that the second is governed (c-commanded) by the first.<ref name="Larson"/> This is in keeping with X'Bar Theory of Phrase Structure Grammar, with Larson's tree structure using the empty Verb to which the V is raised.

Reflexives and reciprocals (anaphors) show this relationship in which they must be c-commanded by their antecedents, such that the (10a) is grammatical but (10b) is not:
{|
|-
| 
 (10) a. ''I showed Mary herself.''<ref name="Larson"/>
     b. ''*I showed herself Mary.''
|}
A pronoun must have a quantifier as its antecedent:
{|
|-
| 
 (11) a. '' I gave every worker his paycheck.''<ref name="Larson"/>
      b. ''*I gave its owner every paycheck.''
|}
Question words follow this order:
{|
|-
| 
 (12) a. ''Who did you give which paycheck?''<ref name="Larson"/>
      b. ''*Which paycheck did you give who?''
|}

The effect of negative polarity means that "any" must have a negative quantifier as an antecedent:
[[File:Larsoncausative.png|thumb|General tree diagram for Larson's proposed underlying structure of a sentence with causative meaning]]
{|
|-
| 
 (13) a. ''I showed no one anything.''<ref name="Larson"/>
      b. ''*I showed anyone nothing.''
|}
These tests with ditransitive verbs that confirm c-command also confirm the presence of underlying or invisible causative verbs. In ditransitive verbs such as ''give someone something'', ''send someone something'', ''show someone something'' etc. there is an underlying causative meaning that is represented in the underlying structure. As seen in example in (9a) above, ''John sent Mary a package'', there is the underlying meaning that 'John "caused" Mary to have a package'.

Larson proposed that both sentences in (9a) and (9b) share the same underlying structure and the difference on the surface lies in that the double object construction "John sent Mary a package" is derived by transformation from a NP plus PP construction "John sent a package to Mary".

==== Beck & Johnson's 2004 double object construction ====

Beck and Johnson, however, give evidence that the two underlying structures are not the same.<ref name=beck>{{cite journal|last1=Sigrid|first1=Beck|last2=Johnson|first2=Kyle|title=Double Objects Again|journal=Linguistic Inquiry|date=2004|volume=35|issue=1|pages=97–124|url=http://people.umass.edu/partee/docs/Beck_and_Johnson_2004.pdf|doi=10.1162/002438904322793356|s2cid=18749803}}</ref> In so doing, they also give further evidence of the presence of two VPs where the verb attaches to a causative verb. In examples (14a) and (b), each of the double object constructions are alternated with NP + PP constructions.
{|
|-
| 
 (14) a. ''Satoshi sent Tubingen the Damron Guide.''<ref name="beck" />
      b. ''Satoshi sent the Damron Guide to Tübingen''.
|}
Beck and Johnson show that the object in (15a) has a different relation to the motion verb as it is not able to carry the meaning of HAVING which the possessor (9a) and (15a) can. In (15a), Satoshi is an animate possessor and so is caused to HAVE kisimen. The PP ''for Satoshi'' in (15b) is of a benefactive nature and does not necessarily carry this meaning of HAVE either.
{|
|-
| 
 (15) a. ''Thilo cooked Satoshi kisimen.''<ref name="beck" />
      b. ''Thilo cooked kisimen for Satoshi''.
|}
The underlying structures are therefore not the same. The differences lie in the semantics and the syntax of the sentences, in contrast to the transformational theory of Larson. Further evidence for the structural existence of VP shells with an invisible verbal unit is given in the application of the adjunct or modifier "again". Sentence (16) is ambiguous and looking into the two different meanings reveals a difference in structure.
{|
|-
| 
 (16) ''Sally opened the door again''.<ref name="beck" />
|}
{{multiple image

}}
However, in (17a), it is clear that it was Sally who repeated the action of opening the door. In (17b), the event is in the door being opened and Sally may or may not have opened it previously. To render these two different meanings, "again" attaches to VPs in two different places, and thus describes two events with a purely structural change.
{|
|-
| 
 (17) a. ''Sally was so kind that she went out of her way to open the door''
         ''once again.''<ref name="beck" />
      b. ''The doors had just been shut to keep out the bugs but Sally opened''
         ''the door again''.
