When to use which vs what?

16
"Which" is more formal when asking a question thatrequires a choice between a number of items. You can use"What" if you want, though. Generally speaking, you canreplace the usage of "which" with "what" and be OKgrammatically. It doesn't always work the other way around,however.


Similarly, you may ask, what is the rule for using that or which?

When referring to objects, though, the rule forusing “that” and “which” correctly issimple: THAT should be used to introduce a restrictiveclause.

who vs which vs that? The main difference between who and that or whichis that you should only use who to refer to a personor people – who is never used to refer to things. Thisrule also applies to organizations, but it's a common mistake touse whoin such contexts: √ Firefighters had to help a man whowas trapped in the car.

Accordingly, what is difference between which and that?

To start with, we use “that” when we referto people, animals, and things. We use “which” when werefer to animals and things. However, the main differencebetween both depends on the clause. If the clause isrestrictive, you need to use the relative pronoun that, without it,the meaning would be unclear.

Which is why meaning?

In that is why, that is a demonstrative pronoun. Inwhich is why, which is a relative pronoun. That in that is why isusually the subject of a sentence or a clause that can stand alone:I want to be involved in town government, and that is why I'mrunning for mayor.

Who or that for a person?

Specifically, I would say that it is fine to use either"that" or "who", but "who" can only be used to refer topeople, while "that" refers to things and people. Oneshould favour the word "who", if they want to clarify that it is aperson, and not a thing, that they are talkingabout.
