Indulgence? European in communist city forgetting it (8)
I believe the answer is:
leniency
'indulgence?' is the definition.
(thesaurus)
'european in communist city forgetting it' is the wordplay.
'european' becomes 'e' (abbreviation e.g. EU).
'in' is an insertion indicator.
'communist' becomes 'lenin' (Lenin is an example**).
'forgetting' suggests deleting specific letters.
'city' with 'it' taken out is 'cy'.
'e' inserted into 'lenin' is 'lenien'.
'lenien'+'cy'='LENIENCY'
(Other definitions for leniency that I've seen before include "Mildness and tolerance" , "Clemency, tolerance" , "Opposite of severity - state of mildness" , "Forbearance" , "The quality of mercy" .)
