Half-rhyme is a poetic technique where the final consonant sounds of two words are similar, but the vowels do not rhyme. Some synonyms for half-rhyme include slant rhyme, off rhyme, imperfect rhyme, and near rhyme. Slant rhyme is similar to half-rhyme, but generally refers to words where the vowel sounds are similar but not identical, such as "screen" and "green." Off rhyme and imperfect rhyme are also used interchangeably with half-rhyme, referring to words that share similar consonant sounds at the end but not the same vowel sounds. The term "near rhyme" is similar, referring to words that almost rhyme, but are not quite a perfect match.
