A homophone is a word that sounds the same as another word but has a different meaning and/or spelling. âFlowerâ and âflourâ are homophones because they are pronounced the same but you certainly canât bake a cake using daffodils. This word set can be confusing, even for word geeks.
Homophones that are spelled differently are also called heterographs. The term homophone may also apply to units longer or shorter than words, such as phrases, letters or groups of letters that are pronounced the same as another phrase, letter or group of letters. A word or unit with this property is said to be homophonous.
