We nappers work daily (9)
I believe the answer is:
newspaper
'daily' is the definition.
(I've seen this before)
'we nappers work' is the wordplay.
'work' indicates anagramming the letters.
'we'+'nappers'='wenappers'
'wenappers' with letters rearranged gives 'NEWSPAPER'.
(Other definitions for newspaper that I've seen before include "It's (mainly) black and white, and read all over!" , "Broadsheet, e.g." , "Daily or weekly publication, keeps us abreast" , "printed edition" , "Journal" .)
