Useful male record, almost complete (7)
I believe the answer is:
helpful
'useful' is the definition.
(similar in meaning)
'male record almost complete' is the wordplay.
'male' becomes 'he' (he refers to a man).
'record' becomes 'L-P' (abbreviation for long play record).
'almost' means to remove the last letter (almost the whole word is kept).
'complete' becomes 'full' (synonyms).
'full' with its final letter taken away is 'ful'.
'he'+'lp'+'ful'='HELPFUL'
(Other definitions for helpful that I've seen before include "Of practical assistance, doing something for another" , "Willing to be of assistance" , "Ready to assist" , "Co-operative" , "Accommodating" .)
