Are there and their homonyms or homophones?
They’re (teehee) homophones!
Homophones are words that are pronounced the same but written differently. Another example is this pair: compliment and complement. (He complimented me on my outfit because of its complementing colors.)
Between Homophones and Homonyms are Homographs, or words that are written the same way but pronounced differently. Think “wind” like Gone With The Wind, and “wind” in “Wind that up!”
Homonyms are words that are spelled and pronounced the same way, like “might” (verbal auxiliary) and “might” (noun). These seem like the scariest of the three, but they’re actually the least confusing–if you meant “might,” but you typed “might,” you’re no worse off. Phew!
