G. Whom is possible instead of who when it is the objective of the verb in the relative clause. (e.g. This is Peter, whom you met at our house last year.)
a. do not often use whom in spoken English, we often keep the preposition after the verb, and normally use who or that, or nothing (not whom) for people. (e.g. This is Peter’s brother, who I went to school with.)
b. can also use whom with a preposition (to whom/ from whom/ with whom etc.) (e.g. The people with whom I work are very nice. ( I work with them))
c. When whom or which have a preposition, the preposition can come at the beginning of the clause. (e.g. I had an uncle in Germany, from who/ whom I inherited a bit of money.) or at the end of the clause. (e.g. I had an uncle in Germany who/ whom I inherited a bit of money from.)
d. can use a preposition before whom (for people) and which (for things) -> to whom/ with whom/ about which/ without which etc. (e.g. Mr. Mike, to whom I spoke at the meeting, is very interested in our proposal.)
e. We often use quantifiers and numbers with Relative Pronouns (many of whom, most of whom, one of which, none of whom, some of which, lots of whom, two of which, etc.) We can use them as subject, object or object of a preposition. (e.g. She has three brothers two of whom are in the army.)
f. All of/ most of etc. + whom/ which: Bob has three brothers. All of them are married. (2 sentences) -> Bob has three brothers, all of whom are married. (1 sentence)
G1. none of/ neither of/ any of/ either of, some of/ many of/ much of/ (a) few of, both of/ half of/ each of/ one of/ two of etc. + whom (people), + which (things)
a. can also say the cause of which/ the name of which etc. (e.g. The building was destroyed in a fire, the cause of which was never discovered.)
b. We can say: the day/ the year/ the time etc. 'something happens' or 'that something happens'. (e.g. Do you remember the day (that) we went to the zoo?)
c. We can say: the reason 'something happens' or 'that/ why something happens'. (e.g. The reason I'm phoning you is to ask your advice. (or The reason that I'm phoning/ The reason why I'm phoning))
