Question words before to-infinitives

Remember!

  • We use a question word such as who, what, where, when, or how before a to-infinitive to express an indirect question about what we should do.
  • We often use a verb such as ask, wonder, (not) decide, (not) tell, or (not) know before the question word + to-infinitive.

Examples

  • We don't know what to do to help the community.
  • She asked how to get to the nearest shopping mall.
