Which or what?
Which or what? We use both which and what to ask questions. We use which when there is a restricted range of answers. We use what more commonly when the range of answers is not restricted: Which is the capital of Liberia? Monrovia or Greenville? What’s the capital of Liberia?
What is a wh word?
Which is a wh -word. We use which to ask questions and to introduce relative clauses. We use which in questions as a determiner and interrogative pronoun to ask for specific information: ‘Which car are we going in?’ he asked Alexander. Which museums did you visit? Which do you prefer? Lemon cake or carrot cake?
