Assist male over record (4)
I believe the answer is:
help
'assist' is the definition.
('help' can be a synonym of 'assist')
'male over record' is the wordplay.
'male' becomes 'he'.
'over' means one lot of letters go next to another.
'record' becomes 'lp' (LP is an example).
'he'+'lp'='HELP'
(Other definitions for help that I've seen before include "Hit from Band" , "SOS, mayday" , "Beatles' album; assist" , "Support" , "Beatles single" .)
