Explanation

  • To try extremely hard to think of something or remember something.

Origin

  • The rack was a medieval torture device used to stretch a person's body, causing extreme pain.
  • The expression uses this imagery metaphorically to describe the mental strain or 'torture' of trying very hard to recall information or solve a difficult problem.
  • It implies intense mental effort, almost to the point of pain or exhaustion.

Alternatives

Slang/Informal:

  • My brain's fried trying to remember.
  • Digging deep (Trying hard to recall)
  • Doing mental gymnastics.

More Formal:

  • I am exerting considerable mental effort to recall...
  • I am endeavoring to remember...

Situational Appropriateness

  • Common in informal and semi-formal situations. The imagery is slightly dramatic, so it might be a bit informal for very serious or formal contexts.

Misunderstanding Warnings

  • The literal imagery is violent, but it's almost always understood metaphorically. Ensure learners know it refers to mental effort, not physical pain.

Examples

  • I've been racking my brain all day trying to remember her name.
  • He racked his brain for a solution, but couldn't think of anything.
  • Let me rack my brain – I know I put that file somewhere.
