wh-clauses: I can’t remember where I put it. How they did it* is a mystery.* Use statement word order.

whether / if for yes/no ideas: I’m not sure whether* it will work.* Use whether (not if) at the start or after prepositions: *Whether we go depends on the weather. It depends on whether…*

what = the thing(s) that: *What I need is a holiday. I didn’t understand what she meant.*
