The use of Who vs. Whom

Many students of English have a problem with deciding when to use Who or Whom.

However, by applying a simple rule, students will no longer suffer


Rule: Use the he/him method to decide which word is correct.

he = who
him = whom

Examples: Who/Whom bought the car?
He bought the car. Therefore, who is correct.

For who/whom should I call?
Should I call him? Therefore, whom is correct.

We all know who/whom pulled that prank.
This sentence contains two clauses: We all know and who/whom pulled that prank. We are interested in the second clause because it contains the who/whom. He pulled that prank. Therefore, who is correct.

We want to know on who/whom the prank was pulled.
This sentence contains two clauses: We want to know and the prank was pulled on who/whom. Again, we are interested in the second clause because it contains the who/whom. The prank was pulled on him. Therefore, whom is correct.
