Tolerant communist accepting English on time (7)
I believe the answer is:
lenient
'tolerant' is the definition.
(synonyms)
'communist accepting english on time' is the wordplay.
'communist' becomes 'lenin' (Lenin is an example).
'accepting' means one lot of letters goes inside another.
'english' becomes 'e' (abbreviation).
'on' is a charade indicator (letters next to each other).
'time' becomes 't' (abbreviation).
'lenin' placed around 'e' is 'lenien'.
'lenien'+'t'='LENIENT'
(Other definitions for lenient that I've seen before include "Compassionate" , "Forbearing" , "Forgiving, gentle" , "Tolerant, rather than strict" , "Easy, soft" .)
