Who or whom? Who becomes whom when it is the object of a sentence. Who is speaking? To whom is she speaking? An easy way to tell the difference is to switch around the words in the sentence and replace who with another pronoun. For example: Who is she speaking to? » She is speaking to (who/whom)? » She is speaking to we. - OR - She is speaking to them.

"She is speaking to them" is correct. Them is an objective pronoun. Therefore, whom is correct. "Whom is she speaking to?" Aided by this knowledge, write the following sentences correctly using who or whom. Click here to print this worksheet. For more of our free grammar and punctuation worksheets, click here.
