Hello everybody.

I have a question concerning the relative pronoun, 'whom'.

When I combine the following two sentences,

1. These are the people.
2. I went to school with them

1st question: These are the people whom I went to school with. This is correct, isn't it?

2nd question: I can't replace 'whiom' with 'who', can I?

3rd question: Can I omit 'whom'?

4th question: I'm going to make a slight change to the sentence 2

sentence 2: We went to school together.

Now, can I combine the sentence 1 and 2?

5th question: Who did you speak to?
Whom did you speak to?
I guess both of them are correct. But strictly speaking,
'who' isn't correct, is it?
