Who vs Whom: What’s the Difference?
At its core, the difference comes down to subject vs object in a sentence.

- Whom = object (the one receiving the action)
Simple Breakdown
- Use who when the person is performing the action
- Use whom when the person is affected by the action

When to Use Who vs Whom (With Examples)
Understanding when to use who vs whom becomes easier with real examples.
Using “Who” (Subject)
Use who when the person is doing the action:

In all these sentences, who performs the action.
Using “Whom” (Object)
Use whom when the person receives the action:
- Whom did you invite?

Here, whom is on the receiving end.
