Slant rhymes have the advantage of being novel, different or unexpected. This can be used to avoid rhyming clichés (e.g. rhyming “love” with “dove”) or obvious rhymes, (“me” and “see” and “be”) and gives the writer greater freedom and flexibility in forming lines of verse. Additionally, many words have no perfect rhyme in English, necessitating the use of slant rhyme.
The use of half rhyme may also enable the construction of longer multisyllabic rhymes than otherwise possible, for instance in rap, free verse or prose poetry.
