Awkward part of record not ending (5)
I believe the answer is:
inept
'awkward' is the definition.
(I know that awkward can be written as inept)
'part of record not ending' is the wordplay.
'part of' becomes 'in' (being in something means being part of it).
'record' becomes 'EP' (abbreviation for extended play record).
'ending' indicates one should take the final letters (the ending of the word).
The final letter of 'not' is 't'.
'in'+'ep'+'t'='INEPT'
(Other definitions for inept that I've seen before include "Hopelessly incapable" , "Awkward, clumsy" , "Showing a lack of competence" , "Lousy" , "Foolish" .)
