Suppletion

Template:Short description Template:More citations needed In linguistics and etymology, suppletion is traditionally understood as the use of one word as the inflected form of another word when the two words are not cognate. For those learning a language, suppletive forms will be seen as "irregular" or even "highly irregular". For example, go:went is a suppletive paradigm, because go and went are not etymologically related, whereas mouse:mice is irregular but not suppletive, since the two words come from the same Old English ancestor.

The term "suppletion" implies that a gap in the paradigm was filled by a form "supplied" by a different paradigm. Instances of suppletion are overwhelmingly restricted to the most commonly used lexical items in a language.

Irregularity and suppletion

An irregular paradigm is one in which the derived forms of a word cannot be deduced by simple rules from the base form. For example, someone who knows only a little English can deduce that the plural of girl is girls but cannot deduce that the plural of man is men. Language learners are often most aware of irregular verbs, but any part of speech with inflections can be irregular.

For most synchronic purposes—first-language acquisition studies, psycholinguistics, language-teaching theory—it suffices to note that these forms are irregular. However, historical linguistics seeks to explain how they came to be so and distinguishes different kinds of irregularity according to their origins.

Most irregular paradigms (like man:men) can be explained by phonological developments that affected one form of a word but not another (in this case, Germanic umlaut). In such cases, the historical antecedents of the current forms once constituted a regular paradigm.

Historical linguistics uses the term "suppletion"<ref> Template:OED </ref> to distinguish irregularities like person:people or cow:cattle that cannot be so explained because the parts of the paradigm have not evolved out of a single form.

Hermann Osthoff coined the term "suppletion" in German in an 1899 study of the phenomenon in Indo-European languages.<ref>Template:Cite book</ref><ref name="Bobaljik2012">Template:Cite book</ref><ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>

Suppletion exists in many languages around the world.<ref>Template:Cite book</ref> These languages are from various language families: Indo-Aryan, Dravidian, Semitic, Romance, etc.

For example, in Georgian, the paradigm for the verb "to come" is composed of four different roots ({{#invoke:Lang|lang}}, {{#invoke:Lang|lang}}, {{#invoke:Lang|lang}}, and {{#invoke:Lang|lang}}; {{#invoke:Lang|lang}}, {{#invoke:Lang|lang}}, {{#invoke:Lang|lang}}, {{#invoke:Lang|lang}}).<ref>Andrew Hippisley, Marina Chumakina, Greville G. Corbett and Dunstan Brown. Suppletion: Frequency, Categories and Distribution of Stems. University of Surrey.[1]</ref>

Similarly, in Modern Standard Arabic, the verb Template:Transliteration ('come') usually uses the form Template:Transliteration for its imperative, and the plural of Template:Transliteration ('woman') is Template:Transliteration.

Some of the more archaic Indo-European languages are particularly known for suppletion. Ancient Greek, for example, has some twenty verbs with suppletive paradigms, many with three separate roots.

Example words

To go

In English, the past tense of the verb go is went, which comes from the past tense of the verb wend, archaic in this sense. (The modern past tense of wend is wended.) See Go (verb).

The Romance languages have a variety of suppletive forms in conjugating the verb "to go", as these first-person singular forms illustrate (second-person singular forms in imperative):<ref>However, some unstandardized languages are chosen in non-standard dialects instead based on their uniqueness. This table below excludes periphrastic tenses.</ref>

The sources of these forms, numbered in the table, are six different Latin verbs:

1. {{#invoke:Lang|lang}} ‘to go, proceed’,<ref>Vadere is cognate with English wade (PIE root *weh₂dʰ-).</ref>
2. {{#invoke:Lang|lang}} ‘to go’
3. {{#invoke:Lang|lang}} ‘to go around’,<ref>Late Lat. *ambitāre is a frequentative form of classical ambio ‘to go around’.</ref> also the source for Spanish and Portuguese {{#invoke:Lang|lang}} ‘to walk’
4. {{#invoke:Lang|lang}} ‘to walk’, or perhaps another Latin root, a Celtic root, or a Germanic root {{#invoke:Lang|lang}} or {{#invoke:Lang|lang}}<ref>Template:Cite journal</ref>
5. {{#invoke:Lang|lang}} suppletive perfective of {{#invoke:Lang|lang}} ‘to be’.<ref>The preterites of "to be" and "to go" are identical in Spanish and Portuguese. Compare the English construction "Have you been to France?" which has no simple present form.</ref>
6. {{#invoke:Lang|lang}} ‘to go along’.

Many of the Romance languages use forms from different verbs in the present tense; for example, French has {{#invoke:Lang|lang}} ‘I go’ from {{#invoke:Lang|lang}}, but {{#invoke:Lang|lang}} ‘we go’ from {{#invoke:Lang|lang}}. Galician-Portuguese has a similar example: {{#invoke:Lang|lang}} from {{#invoke:Lang|lang}} ‘to go’ and {{#invoke:Lang|lang}} from {{#invoke:Lang|lang}} ‘we go’; the former is somewhat disused in modern Portuguese but very alive in modern Galician. Even {{#invoke:Lang|lang}}, from {{#invoke:Lang|lang}} second-person plural of {{#invoke:Lang|lang}}, is the only form for ‘you (plural) go’ both in Galician and Portuguese (Spanish {{#invoke:Lang|lang}}, from {{#invoke:Lang|lang}}).

Sometimes, the conjugations differ between dialects. For instance, the Limba Sarda Comuna standard of Sardinian supported a fully regular conjugation of {{#invoke:Lang|lang}}, but other dialects like Logudorese do not (see also Sardinian conjugation). In Romansh, Rumantsch Grischun substitutes present and subjunctive forms of ir with vom and giaja (both are from Latin vādere and īre, respectively) in the place of mon and mondi in Sursilvan.

Similarly, the Welsh verb {{#invoke:Lang|lang}} ‘to go’ has a variety of suppletive forms such as {{#invoke:Lang|lang}} ‘I shall go’ and {{#invoke:Lang|lang}} ‘we went’. Irish {{#invoke:Lang|lang}} ‘to go’ also has suppletive forms: {{#invoke:Lang|lang}} ‘going’ and {{#invoke:Lang|lang}} ‘will go’.

In Estonian, the inflected forms of the verb {{#invoke:Lang|lang}} ‘to go’ were originally those of a verb cognate with the Finnish {{#invoke:Lang|lang}} ‘to leave’, except for the passive and infinitive.

Good and bad

In Germanic, Romance (except Romanian), Celtic, Slavic (except Bulgarian and Macedonian), and Indo-Iranian languages, the comparative and superlative of the adjective "good" is suppletive; in many of these languages the adjective "bad" is also suppletive.

Ancient Greek

{{#invoke:Labelled list hatnote|labelledList|Main article|Main articles|Main page|Main pages}} Ancient Greek had a large number of suppletive verbs. A few examples, listed by principal parts:

• erkhomai, eîmi/eleusomai, ēlthon, elēlutha, —, — "go, come".
• legō, eraō (erô) / leksō, eipon / eleksa, eirēka, eirēmai / lelegmai, elekhthēn / errhēthēn "say, speak".
• horaō, opsomai, eidon, heorāka / heōrāka, heōrāmai / ōmmai, ōphthēn "see".
• pherō, oisō, ēnegka / ēnegkon, enēnokha, enēnegmai, ēnekhthēn "carry".
• pōleō, apodōsomai, apedomēn, peprāka, peprāmai, eprāthēn "sell".

Bulgarian

In Bulgarian, the word Template:Langx ("man", "human being") is suppletive. The strict plural form, Template:Langx, is used only in Biblical context (like "brethren" as the archaic or symbolic plural of "brother" in English). In modern usage it has been replaced by the Greek loan Template:Langx. The counter form (the special form for masculine nouns, used after numerals) is suppletive as well: Template:Langx (with the accent on the first syllable). For example, Template:Langx ("two, three people"); this form has no singular either. (A related but different noun is the plural Template:Langx, singular Template:Langx ("soul"), both with accent on the last syllable.)

English

In English, the complicated irregular verb to be has forms from several different roots:

• be, been, being—from Old English bēon ("to be, become"), from Proto-Germanic *beuną ("to be, exist, come to be, become"), from Proto-Indo-European *bʰúHt (“to grow, become, come into being, appear”), from the root *bʰuH- ("to become, grow, appear").
• am, is, are—from Middle English am, em, is, aren, from Old English eam, eom, is, earun, earon, from Proto-Germanic *immi, *izmi, *isti, *arun, all forms of the verb *wesaną ("to be; dwell"), from Proto-Indo-European *h₁ésmi ("I am, I exist"), from the root *h₁es- ("to be").
• was, were—from Old English wæs, wǣre, from Proto-Germanic *was, *wēz, from the Proto-Indo-European root *h₂wes- ("to dwell, reside")

This verb is suppletive in most Indo-European languages, as well as in some non-Indo-European languages such as Finnish.

An incomplete suppletion exists in English with the plural of person (from the Latin {{#invoke:Lang|lang}}). The regular plural persons occurs mainly in legalistic use. More commonly, the singular of the unrelated noun people (from Latin {{#invoke:Lang|lang}}) is used as the plural; for example, "two people were living on a one-person salary" (note the plural verb). In its original sense of "populace, ethnic group", people is itself a singular noun with regular plural peoples.

Hungarian

• The verb "to be": {{#invoke:Lang|lang}} ("there is"), {{#invoke:Lang|lang}}, {{#invoke:Lang|lang}} ("I am", "you are"), {{#invoke:Lang|lang}} ("to be"), {{#invoke:Lang|lang}} ("will be"), {{#invoke:Lang|lang}}, {{#invoke:Lang|lang}} ("there is not", "there is neither", replacing {{#invoke:Lang|lang}} + {{#invoke:Lang|lang}} and {{#invoke:Lang|lang}} + {{#invoke:Lang|lang}} respectively).
• The verb {{#invoke:Lang|lang}} ("come") has the imperative {{#invoke:Lang|lang}} (the regular {{#invoke:Lang|lang}} is dated).
• The numeral {{#invoke:Lang|lang}} ("many/a lot") has the comparative {{#invoke:Lang|lang}} and the superlative {{#invoke:Lang|lang}}.
• The adverb {{#invoke:Lang|lang}} ("a little") has the comparative {{#invoke:Lang|lang}} and the superlative {{#invoke:Lang|lang}}.
• Many inflected forms of personal pronouns are formed by using the suffix as the base: {{#invoke:Lang|lang}} ("to me") from {{#invoke:Lang|lang}} (dative suffix) and {{#invoke:Lang|lang}} (first person singular possessive suffix). Even among these, the superessive form ("on") uses the root {{#invoke:Lang|lang}} instead of the suffix {{#invoke:Lang|lang}}.
• The numerals {{#invoke:Lang|lang}}, {{#invoke:Lang|lang}} ("one", "two") have the ordinal forms {{#invoke:Lang|lang}}, {{#invoke:Lang|lang}} ("first", "second"). However they are regular in compounds: {{#invoke:Lang|lang}}, {{#invoke:Lang|lang}} ("eleventh", "twelfth").

Irish

Several irregular Irish verbs are suppletive:

• abair (to say): derived from Old Irish as·beir, from Proto-Indo-European roots *h₁eǵʰs- ("out") and *bʰer- ("bear, carry"). However, the verbal noun rá is derived from Old Irish rád, ultimately from Proto-Indo-European *reh₂dʰ- ("perform successfully").
• bí (to be): derived from Proto-Indo-European *bʰuH- ("grow, become, come into being, appear"). However, the present tense form tá is derived from Old Irish at·tá, from Proto-Celtic *ad-tāyeti, ultimately from Proto-Indo-European *steh₂- ("stand").
• beir (to catch): derived from Proto-Indo-European *bʰer- ("bear, carry"). However, the past tense form rug is derived from Old Irish rouic, which is from Proto-Celtic *ɸro-ōnkeyo-, ultimately from Proto-Indo-European roots *pro- ("forth, forward") and *h₂neḱ- ("reach").
• feic (to see): derived from Old Irish aicci, from Proto-Indo-European *kʷey- ("observe"). However, the past tense form chonaic is derived from Old Irish ad·condairc, ultimately from Proto-Indo-European *derḱ₂- ("see").
• téigh (to go): derived from Old Irish téit, from Proto-Indo-European *stéygʰeti- ("to be walking, to be climbing"). However, the future form rachaidh is derived from Old Irish regae, ultimately from Proto-Indo-European *h₁r̥gʰ- ("go, move"), while the verbal noun dul is from *h₁ludʰét ("arrive").

There are several suppletive comparative and superlative forms in Irish; in addition to the ones listed above, there is:

• fada, "long"; comparative níos faide or níos sia — fada is from Old Irish fota, from Proto-Indo-European *wasdʰos (“long, wide”); compare Latin vāstus (“wide”), while sia is from Old Irish sír ("long, long-lasting"), from Proto-Celtic *sīros (“long”); compare Welsh/Breton hir.<ref>{{#invoke:citation/CS1|citation

Japanese

In modern Japanese, the copulae だ, である and です take な to create "attributive forms" of adjectival nouns<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> (hence the English moniker, "na-adjectives"):

Irrealis 未然形	Adverbial 連用形	Conclusive 終止形	Attributive 連体形	Hypothetical 仮定形	Imperative 命令形
だろ -daro	だっ -daQ で -de に -ni	だ -da	な -na	なら -nara

The "conclusive" and "attributive" forms, だ and な, were constructed similarly, from a combination of a particle and an inflection form of the old verb あり (ari, "to exist").

• で + あり ("conclusive") → であり → であ → だ<ref>{{#invoke:citation/CS1|citation

|CitationClass=web }}</ref>

• に + ある ("attributive") → なる → なん → な<ref>{{#invoke:citation/CS1|citation

|CitationClass=web }}</ref>

(Note: で itself was also a contraction of earlier にて.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>)

In modern Japanese, である ("conclusive") simply retains the older appearance of だ, while です is a different verb that can be used as a suppleted form of だ. Multiple hypotheses have been proposed for the etymology of です, one of which is a contraction of であります:<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>

• で + あり ("adverbial") + ます → であります → です

The basic construction of the negative form of a Japanese verb is the "irrealis" form followed by ない, which would result in such hypothetical constructions as *だらない and *であらない. However, these constructions are not used in modern Japanese, and the construction ではない is used instead.<ref name=handbook>Template:Cite book</ref> This is because *あらない, the hypothetically regular negative form of ある, is not used either, and is simply replaced with ない.

• あら ("irrealis") + ない → ない
• であら ("irrealis") + ない → ではない
• だら ("irrealis") + ない → ではない → じゃない

While the auxiliary ない causes suppletion, other auxiliaries such as ん and ありません do not necessarily.

• あら ("irrealis") + ん → あらん
• あり ("adverbial") + ませ + ん → ありません
• であり ("adverbial") + ませ + ん → でありません

For です, its historical "irrealis" form, でせ has not been attested to create a negative form (only でせう → でしょう has been attested, and there were and are no *でせん and *でせない).<ref>Template:Cite book</ref> Thus, it has to borrow でありません as its negative form instead.<ref name=handbook/>

To express a potential meaning, as in "can do", most verbs use the "irrealis" form followed by れる or られる. する, notably has no such construction, and has to use a different verb for this meaning, できる.

Latin

{{#invoke:Labelled list hatnote|labelledList|Main article|Main articles|Main page|Main pages}}Latin has several suppletive verbs. A few examples, listed by principal parts:

• sum, esse, fuī, futūrus - "be".
• ferō, ferre, tulī or tetulī, lātus - "carry, bear".
• fīō, fierī, factus sum (suppletive and semi-deponent) - "become, be made, happen"

Polish

In some Slavic languages, a few verbs have imperfective and perfective forms arising from different roots. For example, in Polish:

Verb	Imperfective	Perfective
to take	lang}}	lang}}
to say	lang}}	lang}}
to see	lang}}	lang}}
to watch	lang}}	lang}}
to put	lang}}	lang}}
to find	lang}}	lang}}
to go in/to go out (on foot)	lang}}	lang}}
to ride in/to ride out (by car)	lang}}	lang}}

Note that {{#invoke:Lang|lang}}, {{#invoke:Lang|lang}}, {{#invoke:Lang|lang}}, and {{#invoke:Lang|lang}} are prefixes and are not part of the root

In Polish, the plural form of {{#invoke:Lang|lang}} ("year") is {{#invoke:Lang|lang}} which comes from the plural of {{#invoke:Lang|lang}} ("summer"). A similar suppletion occurs in Template:Langx ("year") > Template:Langx (genitive of "years").

Romanian

The Romanian verb {{#invoke:Lang|lang}} ("to be") is suppletive and irregular, with the infinitive coming from Latin fieri, but conjugated forms from forms of already suppletive Latin sum. For example, {{#invoke:Lang|lang}} ("I am"), {{#invoke:Lang|lang}} ("you are"), {{#invoke:Lang|lang}} ("I have been"), {{#invoke:Lang|lang}} ("I used to be"), {{#invoke:Lang|lang}} ("I was"); while the subjunctive, also used to form the future in {{#invoke:Lang|lang}} ("I will be/am going to be"), is linked to the infinitive.

Russian

In Russian, the word Template:Langx ("man, human being") is suppletive. The strict plural form, Template:Langx, is used only in Orthodox Church contexts, with numerals (e. g. Template:Langx "five people") and in humorous context. It may have originally been the unattested Template:Langx. In any case, in modern usage, it has been replaced by Template:Langx, the singular form of which is known in Russian only as a component of compound words (such as Template:Langx). This suppletion also exists in Polish ({{#invoke:Lang|lang}} > {{#invoke:Lang|lang}}), Czech ({{#invoke:Lang|lang}} > {{#invoke:Lang|lang}}), Serbo-Croatian ({{#invoke:Lang|lang}} > {{#invoke:Lang|lang}}),<ref>Template:Cite book</ref> Slovene ({{#invoke:Lang|lang}} > {{#invoke:Lang|lang}}), and Macedonian ({{#invoke:Lang|lang}} (Template:Transliteration) > {{#invoke:Lang|lang}} (Template:Transliteration)).

Generalizations

Strictly speaking, suppletion occurs when different inflections of a lexeme (i.e., with the same lexical category) have etymologically unrelated stems. The term is also used in looser senses, albeit less formally.

The term "suppletion" is also used in the looser sense when there is a semantic link between words but not an etymological one; unlike the strict inflectional sense, these may be in different lexical categories, such as noun/verb.<ref>Paul Georg Meyer (1997) Coming to know: studies in the lexical semantics and pragmatics of academic English, p. 130: "Although many linguists have referred to [collateral adjectives] (paternal, vernal) as 'suppletive' adjectives with respect to their base nouns (father, spring), the nature of ..."</ref><ref>Aspects of the theory of morphology, by Igor Mel’čuk, p. 461</ref>

English noun/adjective pairs such as father/paternal or cow/bovine are also referred to as collateral adjectives. In this sense of the term, father/fatherly is non-suppletive. Fatherly is derived from father, while father/paternal is suppletive. Likewise cow/cowish is non-suppletive, while cow/bovine is suppletive.

In these cases, father/pater- and cow/bov- are cognate via Proto-Indo-European, but 'paternal' and 'bovine' are borrowings into English (via Old French and Latin). The pairs are distantly etymologically related, but the words are not from a single Modern English stem.

Weak suppletion

The term "weak suppletion" is sometimes used in contemporary synchronic morphology in reference to sets of stems whose alternations cannot be accounted for by synchronically productive phonological rules. For example, the two forms child/children are etymologically from the same source, but the alternation does not reflect any regular morphological process in modern English: this makes the pair appear to be suppletive, even though the forms go back to the same root.

In that understanding, English has abundant examples of weak suppletion in its verbal inflection: e.g. bring/brought, take/took, see/saw, etc. Even though the forms are etymologically related in each pair, no productive morphological rule can derive one form from the other in synchrony. Alternations just have to be learned by speakers — in much the same way as truly suppletive pairs such as go/went.

Such cases, which were traditionally simply labelled "irregular", are sometimes described with the term "weak suppletion", so as to restrict the term "suppletion" to etymologically unrelated stems.
