Rhyme is a repetition of similar sounds in the final stressed syllables and any following syllables of two or more words. For example, "sight" and "flight" rhyme because they have the same final stressed vowel and all following sounds are identical. There are different types of rhymes, including perfect rhymes, which are the most common kind, and near rhymes, which are words that almost rhyme but not quite. If youre looking for words that rhyme with "what," you can find them using online rhyming dictionaries like RhymeZone or RapPad.
