Passes English, with minor mistakes? (7)
I believe the answer is:
elapses
'passes' is the definition.
('elapse' can be a synonym of 'pass')
'english with minor mistakes?' is the wordplay.
'english' becomes 'e' (abbreviation).
'with' means one lot of letters go next to another.
'minor mistakes?' becomes 'lapses' (lapse can mean a mistake or error).
'e'+'lapses'='ELAPSES'
(Other definitions for elapses that I've seen before include "Passes (in time)" , "Slips away" .)
