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 are words that sound alike, but have different meanings and spellings. They are the sets of words that you probably learned in elementary school, though your teacher may have used the broader category of homonyms.
