perfect rhyme

Perfect rhyme — also called full rhyme, exact rhyme, or true rhyme — is a form of rhyme between two words or phrases, satisfying the following conditions:

• The stressed vowel sound in both words must be identical, as well as any subsequent sounds. For example, "sky" and "high"; "skylight" and "highlight".
• The articulation that precedes the vowel in the words must differ. For example, "bean" and "green" is a perfect rhyme, while "leave" and "believe" is not.
