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 the same, but have different meanings and sometimes even different spellings, Breen said. Homophones are best understood when read rather than pronounced. The words 'bear' and 'bare' are pronounced the same, but they have very different meanings, he said. Homographs have the same spelling, and might have similar pronunciation. The word 'offensive' can have two different meanings, depending on where the stress is placed on the word, Breen said.
