What are homophones? words that are spelled incorrectly several times in one paper
words that are spelled exactly as they sound
words that have different meanings depending on how they are used
words that have the same sound but different spellings and meaning

A homophone is a word that is pronounced the same (to varying extent) as another word but differs in meaning. A homophone may also differ in spelling. The two words may be spelled the same, as in rose (flower) and rose (past tense of rise), or differently, as in rain, reign, and rein.

I hope its help for you

have a great day
