Pay to get something off one's chest? (5,2)
I believe the answer is:
cough up
'pay' is the definition.
(to cough up can mean to pay money)
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for cough up that I've seen before include "Pay out under duress" , "Clear throat and pay what you owe" , "(Reluctantly) contribute" , "Clear throat to part with money" , "Pay money with some reluctance - clear throat" .)
