ELI5: When to use 'who' and when to use 'whom'?

Note: using the words 'objective' and 'subjective' won't help at all like every google-searched answer I have ever seen (I'm 26 not 5 and I still don't know what they mean.)

Which to us depends on the sentence construction. The best explanation is this: if you are using *him*, *her*, or *them*, use *whom*; if you are using *he*, *she*, or *they*, use *who*.

Examples:

> "To whom did you give it?"

> "To him, over there."

> ---------------------------------------

> "Who did it?"

> "He did."
