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.
If they are pronounced differently then they are also heteronyms â for example, bow (the front of a ship) and bow (a ranged weapon). Homophones (literally same sound) are usually defined as words that share the same pronunciation, regardless of how they are spelled. If they are spelled the same then they are also homographs (and homonyms); if they are spelled differently then they are also heterographs (literally different writing).
