Pronouns Help?

Question

I have a hard time with pronouns. Not the simple ones but Reflexive, Intensive, Demonstrative, and Interrogative.
I get mixed when to put Who in a sentence and when to put Whom.

Thanks in advance
I would love helpful handy tips to remember each of them

Answer 1

If you can replace a word with "he" or "she," then it is the subject of the sentence and you should use "who." If you can replace the word with "him" or "her," it is the object and you should use "whom."
Hope that helps!

it has a very good explanation about the different pronouns' type.
Releted to who and whom:
"Make a simple substitution. In any sentence or clause, substitute he for who, him for whom. Using the masculine forms is advised because they sound so much like who and whom"

Answer 3

Whom is the objective form of who, so you would use it when it's acting as an object (as opposed to a subject). Think of it this way, if it's preceded by a preposition, it's most likely correct to use whom.
e.g. She gave it to whom?
And it works the other way too
Whom did she give it to? (which is more like how people really speak)
But if you're referring to someone who did something (like I just did-hehe), it's who
e.g. Who is coming with me?
So "who" does something; "whom" has something done to it.

It's pretty tricky, but most people won't notice if you mess it up so I wouldn't fret too much about it.

Answer 4

Here is a quick trick.

Rewrite your sentence to use him/her/them or he/she/they. If you use him, her, or them, then you should use whom. If you use he, she, or they, then you should use who.

Another way to think of it is:
Who is a subject pronoun (represents the subject of the verb).
Whom is an object pronoun (represents the object of the verb).
