Answer - pep varies daily (9)
I believe the answer is:
newspaper
'daily' is the definition.
(I've seen this before)
'answer pep varies' is the wordplay.
'varies' is an anagram indicator.
'answer'+'pep'='answerpep'
'answerpep' anagrammed gives 'NEWSPAPER'.
(Other definitions for newspaper that I've seen before include "Broadsheet, e.g." , "Journal" , "part of the media" , "Eg, The Times" , "Daily or weekly publication, keeps us abreast" .)
