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.
These sets of words are called homophones (or sometimes homonyms), and they can cause a lot of trouble for spellers. What Are Homophones? Homophones are two or more words that sound alike but that are spelled differently and have different meanings. Here are a few homophone pairs: deer and dear, billed and build, and sew, so, and sow. Homophones occur in English because there are multiple ways to spell the same sound. For example: The sound of /n/ can be spelled with the letter N or the letter combination KN, resulting in the homophones night and knight. The sound of /Ä/ can be spelled A-consonant-E or AY (among other possible spellings), giving us daze and days.
