What it means...

Completely under someone else's control, with very little freedom.

When you are under someone's thumb, that person dictates what you do and you have little say in your own choices.

It's used with a negative tone, implying the control is unfair or limiting.

Use it when…

  • When a partner controls all financial and social decisions in a relationship
  • When an employee can't act without constant approval from a micromanaging boss
  • When a person's choices are entirely shaped by someone else's expectations

Don’t confuse with...
