collocations with brain

The brain is the powerhouse organ of the human body that controls all of its life functions. In English, it can be used as a standard medical term, but it can also be used in many idioms associated with intelligence and thinking. Let’s look at some common collocations using this word!


To spend time, usually with a group of people, spontaneously producing many ideas or solutions to a problem. You could literally think of a “storm” of ideas brewing in one’s brain.

B: I think I’ve heard this brain teaser before.

To receive information by asking someone about a subject they know about better than you do.

Just as you can pick berries from a bush or fruit from a true, you could imagine someone “picking” knowledge from someone else.

This expression is another way of referring to someone who has orchestrated something “behind the scenes.”
