Who vs Whom | Ask Linda! | English Grammar
Who and whom are another two words that often cause confusion. There is a simple trick to deciding which one to use in a sentence. Who is used to refer to the subject of a sentence and whom is used to refer to the object. The usage of these two words is the same as he and him. He is the subject and him is the object. If you are confused about which one you should use, look at the sentences and check whether he or him should be used. If it’s he, then you should use who. If it’s him, then whom should be used.
