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.
Today we have an exercise on homophones, which, as you have probably guessed from the title of the lesson, means words that are spelled differently but sound the same (They are sometimes called heterographs, but it's not important to get that technical).
