In Paris, who may get into performance free? (6)
I believe the answer is:
acquit
'free?' is the definition.
(to free from legal charges)
'in paris who may get into performance' is the wordplay.
I cannot quite understand how this works, but
'paris who' could be 'qui' ('who' in French) and 'qui' is found within the answer.
'performance' could be 'act' (act is a kind of performance) and 'act' is present in the leftover letters.
This accounts for all the letters.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for acquit that I've seen before include "Pronounce innocent" , "Declare (someone) not guilty of a crime" , "Free - act" , "Exonerate" , "Discharge from court as innocent" .)
