Record, single, needs volume for example (7)
I believe the answer is:
epitome
'example' is the definition.
(epitome is a kind of example)
'record single needs volume' is the wordplay.
'record' becomes 'ep'.
'single' becomes 'i' (one).
'needs' says to put letters next to each other.
'volume' becomes 'tome' (I've seen this before).
'ep'+'i'+'tome'='EPITOME'
'for' is the link.
(Other definitions for epitome that I've seen before include "Ideal example" , "Archetype, typical example" , "classic example" , "Essence or embodiment" , "Summary of a written work" .)
