Charge for fifty per cent of coffee (3)
I believe the answer is:
fee
'charge for' is the definition.
(I've seen this in other clues)
'fifty per cent of coffee' is the wordplay.
'FEE' is hidden within the letters.
But, I'm unsure how the hidden word is indicated.
Can you help me to learn more?
(Other definitions for fee that I've seen before include "Amount paid for job" , "Sum payable to professional person for services" , "Charge for professional services" , "Payment to a professional for services" , "Cost" .)
