A personal assistant for each daily (5)
I believe the answer is:
paper
'daily' is the definition.
(newspaper)
'a personal assistant for each' is the wordplay.
'a personal assistant' becomes 'PA' (abbreviation).
'for each' becomes 'per' (per person).
'pa'+'per'='PAPER'
(Other definitions for paper that I've seen before include "Journal" , "Writing sheet(s)?" , "News publication" , "Set of written exam questions" , "conference presentation" .)
