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 are pronounced the same but differ in meaning, derivation, or spelling. Homonyms are words that are both homographs and homophones: words that are spelled and pronounced the same but differ in meaning or derivation. Heteronyms are a type of homograph. They are words that are spelled the same but differ in meaning and pronunciation. All heteronyms are also homographs, but not all homographs are heteronyms. Many heteronyms are similar in meaning (especially a related noun and verb are spelled the same but pronounced differently), while others are wholly unrelated.
