what is a homonym for the word group ?
Generally, the term homonym refers both to homophones (words that are pronounced the same but have different meanings, such as pair and pear) and to homographs (words that are spelled the same but have different meanings, such as bow your head and tied in a bow).
A homophone is a word that is pronounced the same as another word but differs in meaning, and may differ in spelling. The words may be spelled the same, such as rose (flower) and rose (past tense of rise), or differently, such as carat, caret, and carrot, or to, two, and too.
