Demand and get payment absolutely right (5)
I believe the answer is:
exact
'absolutely right' is the definition.
(I've seen this before)
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for exact that I've seen before include "Strict" , "Demand, extort" , "Specific" , "Spot on, precise" , "19 [WREST]" .)
