He's on record as providing service (4)
I believe the answer is:
'service' is the definition.
(I know that service can be written as help)
'he's on record as' is the wordplay.
'on' says to put letters next to each other.
'record as' becomes 'lp' (abbreviation for long play record. I am not sure about the 'as' bit.).
'providing' acts as a link.
Can you help me to learn more?
(Other definitions for help that I've seen before include "Serve" , "Guide" , "SOS, mayday" , "Contribute to the success of" , "Assist, aid" .)
