We use "which" as a determiner to ask a question about a specific group of people or things:

Which restaurant did you go to?
Which countries in South America have you visited?

When we are asking a general question we use "what" as a determiner:

What films do you like?
What university did you go to?



Hi Team.
Help me with this, please..
Which ones of these interrogative sentences is correct?
1. Why isn't there "to" after verb "want" in the sentence?
2. Why after verb "want" there's no "to" in the sentence?
Would you like to explain, please?
Thank you.

Hello Nizam,

1 is almost correct -- instead I'd say 'Why isn't there a 'to' after the verb 'want' in the sentence?'. 2 is almost correct, also -- instead I'd recommend 'Why is there no 'to' after the verb 'want' in the sentence?'.

If we are asking for the definition of a term, what should we use----what or who? For example, which of the following sentences is right?
What is a zookeeper?
Who is a zookeeper?


Hi naghmairam,

To ask for a definition you should use 'what'. If you ask 'who' then you will be told the name of the person who has this job.

Dear Sir,

Which one is correct.
1. Sara can play _a_ guitar.


Sara can play _the_ guitar.

Hello Gobin Sonowal,

Both 'a' and 'the' are possible here - which one is correct depends on the context. Please see our English Grammar section on Articles and our Quick Grammar page on Articles for explanations of the differences between them.

hello sir
the statement : what films do you like?
it can't be understood that its also a question about (type) of films you prefer ?
thank you

Hello dentist iraq,

You are correct: this can be a question about specific films of kinds of film, depending on the context. A more likely question would be 'What kind(s) of films do you like?' if the context did not make it clear that we were talking about types.

Hello. Who can explaine me, what differeсе between "Which restaurant did you go to?" and "What university did you go to?" Why in first example "Wich" and "what" in second? Fore several reasons I think there are two spesific groups, aren`n they?

Hello Xiryrgus,

I explained this a bit more in my response to andrew international below. Please take a look at that and then if you still have a question after that, don't hesitate to ask.
