In which By Which

[hon123456]

Dear all,

I want to know more about the grammar of "In which" and "by
which", could you please
give me some link on it? By the way, what is the grammar jargon for
"in which" and "by which"?
I want to use the grammar jargon to search for the above mentioned.
Thanks

I don't think I ever learned a special grammatical term for "in which"
or "by which". Each of them is a prepositional phrase with a relative
pronoun as the object of the preposition. There is a Wikipedia
article, in this list:

"adpositional complement". You might try searching for that, but it's
not a term I know, and a brief search that I made didn't seem very
productive.

It's easier to talk about a whole sentence than to explain a short
phrase. In "This is the house in which I live," the relative pronoun
"which" is used to connect two statements: "This is the house," and "I
live in the house."

The relative pronoun in the second statement stands for "the house"
(you could think of it as an abbreviation for "the house"), and is
also the object of the preposition "in" in the second statement, so
that the two statements become a single sentence.
