Record one article: time for a descriptive word (7)
I believe the answer is:
epithet
'a descriptive word' is the definition.
(I've seen this before)
'record one article time' is the wordplay.
'record' becomes 'ep'.
'one' becomes 'i' (Roman numeral).
'article' becomes 'the' (the 'definite article' part of speech).
'time' becomes 't'.
'ep'+'i'+'the'+'t'='EPITHET'
'for' acts as a link.
(Other definitions for epithet that I've seen before include "Tag" , "Phrase expressing some quality of a person or thing" , "Descriptive term used to express a real quality" , "Sobriquet" , "qualifier" .)
