[Anonymous]

When can I used the word Whom instead of who in a sentence?

When can I used the word Whom instead of who in a sentence?

Use whom as an object and who as a subject:

OBJECT:
They know him
They know whom?
Question formation: Whom do they know?

SUBJECT:
They know him.
Who knows him?

SUBJECT AND OBJECT:
They know him.
Who knows whom?
Question formation: Whom does who know?
