Which is used when it you are using a non-essential modifier. A non-essential modifier is a modifier that is not vital to the meaning of the sentence. For example:

"John went to the red house, which was recently renovated, to campaign for the Senator."

In that sentence, the phrase "which was recently renovated" could be removed and the sentence would still make logical sense.

The thing with in which confused me as well. You have to realize that "in" is a preposition. So with the statement "in which" which is the obeject of the preposition. The key is to just make sure that whether you use "which" or "in which" that those phrases are next to the words they are meant to modify

"where" can only be used to modify an actual physical location. "when" can only be used to modify time. "That" and "which" can only modify things, and never people. "Who" and "whom" can only modify people. "Whose" can modify people or things. Hope this helps.

Nice one indeed! Thanks!

which is general and that is restrictive.

"I'm in the third room that has a red door knob"
"I'm in the third room, which has a red door knob"

In the first sentence we're not necessarily referring to the third room, but the third room among the rooms with red door knobs.

In the second sentence we're referring to the third room, which just happened to have the red door knob.

hope it helps

Please elaborate the example explanations a l'l more!

Analyst has done nothing but differentiated between "which" and "that"
Check out this one : https://www.beatthegmat.com/that-vs-which-t12537.html

hope that suffice.

ok perhaps i didn't elaborate enough on my thought process ..

Another way to look at it is you use 'that' whenever there is varieties of the subject you're referring to and you want to restrict your description to just that particular subject in context that you want to refer to.

and 'which' whenever the subject you refer to is general.

It's the same thing as essential vs. nonessential somebody else used somewhere on the thread. Just diff thought process I guess..

another example,

The Big Bang Theory that [blah blah]
The Big Bang Theory, which [blah blah]

we know there is only one theory of big bang, so using 'that' would imply there are multiple theories of big bang. but that's not the case, so you use 'which'.

maybe i'm just bad at explaining my thought..but using the thought process that I described, i do answer correctly any 'that' vs 'which ' questions. so it works for me, at least. lol.
