In the study of phonology
Phonology
Phonology is, broadly speaking, the subdiscipline of linguistics concerned with the sounds of language. That is, it is the systematic use of sound to encode meaning in any spoken human language, or the field of linguistics studying this use...

Linguistics
Linguistics is the scientific study of human language. Linguistics can be broadly broken into three categories or subfields of study: language form, language meaning, and language in context....

, the rime or rhyme of a syllable
Syllable
A syllable is a unit of organization for a sequence of speech sounds. For example, the word water is composed of two syllables: wa and ter. A syllable is typically made up of a syllable nucleus with optional initial and final margins .Syllables are often considered the phonological "building...

 consists of a nucleus and an optional coda
Syllable coda
In phonology, a syllable coda comprises the consonant sounds of a syllable that follow the nucleus, which is usually a vowel. The combination of a nucleus and a coda is called a rime. Some syllables consist only of a nucleus with no coda...

. It is the part of the syllable used in poetic rhyme
Rhyme
A rhyme is a repetition of similar sounds in two or more words and is most often used in poetry and songs. The word "rhyme" may also refer to a short poem, such as a rhyming couplet or other brief rhyming poem such as nursery rhymes.-Etymology:...

, 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
Vowel
In phonetics, a vowel is a sound in spoken language, such as English ah! or oh! , pronounced with an open vocal tract so that there is no build-up of air pressure at any point above the glottis. This contrasts with consonants, such as English sh! , where there is a constriction or closure at some...

 to the end. For example, /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. For instance, the rime of the second syllables of the words bottle and fiddle is just /l/, a liquid consonant
Liquid consonant
In phonetics, liquids or liquid consonants are a class of consonants consisting of lateral consonants together with rhotics.-Description:...

.

"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
Rhyme
A rhyme is a repetition of similar sounds in two or more words and is most often used in poetry and songs. The word "rhyme" may also refer to a short poem, such as a rhyming couplet or other brief rhyming poem such as nursery rhymes.-Etymology:...

. This distinction is not made by some linguists and does not appear in most dictionaries.

Rhyme structure

The simplest model of syllable structure divides each syllable into an optional onset, an obligatory nucleus, and an optional coda
Syllable coda
In phonology, a syllable coda comprises the consonant sounds of a syllable that follow the nucleus, which is usually a vowel. The combination of a nucleus and a coda is called a rime. Some syllables consist only of a nucleus with no coda...

. The illustration to the right demonstrates this model with the English words cat and sing.
There exist, however, many arguments for a hierarchical relationship, rather than a linear one, between the syllable constituents. This hierarchical model groups the syllable nucleus and coda into an intermediate level, the rime, as shown in the illustration to the left. The hierarchical model accounts for the role that the nucleus+coda constituent plays in verse (i.e., rhyming words such as cat and bat are formed by matching both the nucleus and coda, or the entire rhyme), and for the distinction between heavy and light syllables
Syllable weight
In linguistics, syllable weight is the concept that syllables pattern together according to the number and/or duration of segments in the rime. In classical poetry, both Greek and Latin, distinctions of syllable weight were fundamental to the meter of the line....

 in Old English scipu and wordu.

Just as the rime branches into the nucleus and coda, the nucleus and coda may each branch into multiple phoneme

 include a medial contrast between /i/ and /j/, where the /i/ functions phonologically as a glide rather than as part of the nucleus. In addition, many reconstructions of both Old and Middle Chinese include complex medials such as /rj/, /ji/, /jw/ and /jwi/. The medial groups phonologically with the rime rather than the onset, and the combination of medial and rime is collectively known as the final.

Some linguists, especially when discussing the modern Chinese varieties, use the terms "final" and "rime/rhyme" interchangeably. In historical Chinese phonology
Historical Chinese phonology
Historical Chinese phonology deals with reconstructing the sounds of Chinese from the past. As Chinese is written with logographic characters, not alphabetic or syllabary, the methods employed in Historical Chinese phonology differ considerably from those employed in, for example, Indo-European...

, however, the distinction between "final" (including the medial) and "rime" (not including the medial) is important in understanding the rime dictionaries
