Glad minion is gathering paperwork, in short (5)
I believe the answer is:
admin
'paperwork in short' is the definition.
'admin' can be an answer for 'paperwork' (administrative work). I am not sure about the 'in short' bit.
'glad minion is gathering' is the wordplay.
'is gathering' says the answer is hidden in the clue (parts of the clue hold or gather the answer).
'ADMIN' is hidden in the letters of 'glad minion'.
Can you help me to learn more?
(Other definitions for admin that I've seen before include "Business organisation" , "Paperwork (abbr)" , "Management function" , "Process of running an organisation (abbr)" , "Management (abbr.)" .)
