I believe the answer is:

duress

I'm a little stuck... Click here to teach me more about this clue!

'pressure' is the definition.
(I've seen this before)

I don't understand the remainder of the clue.

(Other definitions for duress that I've seen before include "Constraint, force" , "Force, coercion" , "Coercion, compulsion" , "Excessive pressure" , "Coercion, pressure" .)

I've seen this clue in The Hindu.
