Take only what is right? (5)
I believe the answer is:
exact
'take' is the definition.
(exacting is a kind of taking)
'only what is right?' is the wordplay.
I cannot quite understand how this works, but
'right?' could be 'act' (right is a kind of act) and 'act' is present in the answer.
The remaining letters 'ex' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for exact that I've seen before include "Demand, extort" , "Precisely accurate" , "correct in every detail" , "Demand and obtain" , "Not approximate; inflict (revenge) on someone" .)
