School briefly allowed to be partnered in immoral activity (9)
I believe the answer is:
complicit
'be partnered in immoral activity' is the definition.
I know nothing about this answer so I can't judge whether it can be defined by this definition.
'school briefly allowed' is the wordplay.
'school briefly' becomes 'comp' (short for comprehensive; 'briefly' indicates an abbreviation).
'allowed' becomes 'licit' (I've seen this in other clues).
'comp'+'licit'='COMPLICIT'
'to' is the link.
Can you help me to learn more?
(Other definitions for complicit that I've seen before include "Conniving" , "Involved with others in law-breaking" , "Nefariously involved (in)" , "Being party to a crime" , "Involved with others in illegality" .)
