Rhyme is the repetition of identical or similar terminal sound combination of words. Rhyming words are generally placed at a regular distance from each other. In verse they are usually placed at the end of the corresponding lines.
Identity and similarity of sound combinations may be relative. For instance, we distinguish between full rhymes and incomplete rhymes. The full rhyme presupposes identity of the vowel sound and the following consonant sounds in a stressed syllable, including the initial consonant of the second syllable (in polysyllabic words), we have exact or identical rhymes.
Incomplete rhymes present a greater variety They can be divided into two main groups: vowel rhymes and consonant rhymes. In vowel-rhymes the vowels of the syllables in corresponding words are identical, but the consonants may be different as in flesh - fresh -press. Consonant rhymes, on the contrary, show concordance in consonants and disparity in vowels, as in worth - forth, tale - tool -treble - trouble; flung - long.
