A clause beginning with what can refer to a thing or things without naming them first.
The idea
What combines the meaning of the thing or things and a relative link. The whole clause can be a subject or an object; inside it, what can also be a subject or an object.
Examples
- What you said surprised me.
- Mina found what she needed in the cupboard.
- What matters most is a safe journey.
- We shared what we grew in the garden.
- Please write down what the guide recommends.
- What fell from the shelf was an empty box.

Watch out
Do not put what after a noun already naming the thing: say the book that I borrowed, not the book what I borrowed.
