Release American gin around November (7)
I believe the answer is:
unstrap
'release' is the definition.
(to release from straps)
'american gin around november' is the wordplay.
'american' becomes 'US' (abbreviation for United States).
'gin' becomes 'trap' (I've seen this before).
'around' indicates putting letters inside.
'november' becomes 'N' (phonetic alphabet: alpha, bravo, charlie etc.).
'us'+'trap'='ustrap'
'ustrap' enclosing 'n' is 'UNSTRAP'.
(Other definitions for unstrap that I've seen before include "Loosen tie" , "Release" , "Remove fastenings from" , "loose" .)
