In some theories of phonology, syllable structures are displayed as [[Parse tree|tree diagrams]] (similar to the trees found in some types of syntax). Not all phonologists agree that syllables have internal structure; in fact, some phonologists doubt the existence of the syllable as a theoretical entity.<ref>For discussion of the theoretical existence of the syllable see {{cite web |title=CUNY Conference on the Syllable |url=http://www.cunyphonologyforum.net/syllable.php |website=CUNY Phonology Forum |publisher=CUNY Graduate Center |access-date=21 June 2022 |archive-url=https://web.archive.org/web/20150923211920/http://www.cunyphonologyforum.net/syllable.php |archive-date=23 September 2015}}</ref>

There are many arguments for a hierarchical relationship, rather than a linear one, between the syllable constituents. One hierarchical model groups the syllable nucleus and coda into an intermediate level, the ''rime''. The hierarchical model accounts for the role that the ''nucleus''+''coda'' constituent plays in [[Verse (poetry)|verse]] (i.e., [[Rhyme|rhyming]] words such as ''cat'' and ''bat'' are formed by matching both the nucleus and coda, or the entire rime), and for the [[Syllable weight|distinction between heavy and light syllables]], which plays a role in phonological processes such as, for example, [[sound change]] in [[Old English]] {{lang|ang|scipu}} and {{lang|ang|wordu}}, where in a process called high vowel deletion (HVD), the nominative/accusative plural of single light-syllable roots (like "*scip-") got a "u" ending in OE, whereas heavy syllable roots (like "*word-") would not, giving "scip-u" but "word-∅".<ref>{{cite web|url=http://bermudez-otero.com/SHEL9.pdf|title=The life cycle of High Vowel Deletion in Old English: from prosody to stratification and loss|last=Bermúdez-Otero|first=Ricardo|year=2015|page=2}}</ref><ref>{{cite book| last1=Fikkert|first1=Paula|last2=Dresher|first2=Elan|last3=Lahiri|first3=Aditi|year=2006|title=The Handbook of the History of English|url=https://www.ling-phil.ox.ac.uk/files/fikkert_dresher_lahiri_2006.pdf|chapter=Chapter 6, Prosodic Preferences: From Old English to Early Modern English|pages =134–135|isbn=9780470757048}}</ref><ref>{{cite book | title = A Prosodic Grammar of Chinese | last = Feng | first = Shengli | page = 3 | publisher = University of Kansas | year = 2003}}</ref>

==== Body ====
[[Image:Syllable body coda.svg|thumb|upright=2.5|Left-branching hierarchical model]]
In some traditional descriptions of certain languages such as [[Cree language|Cree]] and [[Ojibwe language|Ojibwe]], the syllable is considered left-branching, i.e. onset and nucleus group below a higher-level unit, called a "body" or "core". This contrasts with the coda.

==== Rime ====

The '''rime''' or '''rhyme''' of a syllable consists of a [[#Nucleus|nucleus]] and an optional [[#Coda|coda]]. It is the part of the syllable used in most [[Rhyme|poetic rhyme]]s, and the part that is lengthened or stressed when a person elongates or stresses a word in speech.

The rime is usually the portion of a syllable from the first [[vowel]] to the end. For example, {{IPA|/æt/}} is the rime of all of the words ''at'', ''sat'', and ''flat''. However, the nucleus does not necessarily need to be a vowel in some languages, such as English. For instance, the rime of the second syllables of the words ''bottle'' and ''fiddle'' is just {{IPA|/l/}}, a [[liquid consonant]].

Just as the rime branches into the nucleus and coda, the nucleus and coda may each branch into multiple [[phoneme]]s. The limit for the number of phonemes which may be contained in each varies by language. For example, [[Japanese language|Japanese]] and most [[Sino-Tibetan languages]] do not have consonant clusters at the beginning or end of syllables, whereas many Eastern European languages can have more than two consonants at the beginning or end of the syllable. In English, the onset may have up to three consonants, and the coda four.<ref name="Hultzén">{{Cite journal |last=Hultzén |first=Lee S. |date=1965 |title=Consonant Clusters in English |url=https://www.jstor.org/stable/454173 |journal=American Speech |volume=40 |issue=1 |pages=5–19 |doi=10.2307/454173 |jstor=454173 |issn=0003-1283|url-access=subscription }}</ref>

''Rime'' and ''rhyme'' are variants of the same word, but the rarer form ''rime'' is sometimes used to mean specifically ''syllable rime'' to differentiate it from the concept of poetic [[rhyme]]. This distinction is not made by some linguists and does not appear in most dictionaries.

{{Main|Syllable weight}}

<!-- Cross-linguistically, there is evidence for a hierarchy of syllable weights according to syllable structure. -->
A '''heavy syllable''' is generally one with a ''branching rime'', i.e. it is either a ''closed syllable'' that ends in a consonant, or a syllable with a ''branching nucleus'', i.e. a long vowel or [[diphthong]]. The name is a metaphor, based on the nucleus or coda having lines that branch in a tree diagram.

In some languages, heavy syllables include both VV (branching nucleus) and VC (branching rime) syllables, contrasted with V, which is a '''light syllable'''.
In other languages, only VV syllables are considered heavy, while both VC and V syllables are light.
Some languages distinguish a third type of '''superheavy syllable''', which consists of VVC syllables (with both a branching nucleus and rime) or VCC syllables (with a coda consisting of two or more consonants) or both.

In [[mora (linguistics)|moraic theory]], heavy syllables are said to have two moras, while light syllables are said to have one and superheavy syllables are said to have three. [[Japanese phonology]] is generally described this way.

Many languages forbid superheavy syllables, while a significant number forbid any heavy syllable. Some languages strive for constant syllable weight; for example, in stressed, non-final syllables in [[Italian language|Italian]], short vowels co-occur with closed syllables while long vowels co-occur with open syllables, so that all such syllables are heavy (not light or superheavy).

The difference between heavy and light frequently determines which syllables receive [[stress (linguistics)|stress]] – this is the case in [[Latin]] and [[Arabic language|Arabic]], for example. The system of [[meter (poetry)|poetic meter]] in many classical languages, such as [[Classical Greek]], [[Classical Latin]], [[Tamil language|Old Tamil]] and [[Sanskrit language|Sanskrit]], is based on syllable weight rather than stress (so-called ''quantitative rhythm'' or ''quantitative meter'').
