The words whos and whose are antonyms context clues homonyms synonyms?

Answer 1

"whos" is not a word.

"who's" and "whose" are homophones -- they sound identical. they are not homonyms, synonym, nor antonyms.

"who's" is a contraction for "who is" or sometimes "who has" as in the examples "who's at my door?" and "who's eaten my cake?"

"whose" is a possessive form of "who" -- "it was mark whose dog got into our garbage" or "whose dog is this in my garbage?"

"who's" works similarly to "what's" in most sentences, one refering to people and the other to things.

"whose" is the possessive of "who," just like "my" is the possessive of "i/me" and "your" is the possessive of "you."
