Neatly dressed agent with stuff sent up (6)
I believe the answer is:
dapper
'neatly dressed' is the definition.
The answer and definition are different parts of speech. However, past participle verbs and adjectives can sometimes mean the same thing.
'agent with stuff sent up' is the wordplay.
'agent' becomes 'rep' (short for representative).
'with' is a charade indicator (letters next to each other).
'stuff' becomes 'pad' (pad is a kind of stuff).
'sent up' says the letters should be written in reverse.
'rep'+'pad'='reppad'
'reppad' written backwards gives 'DAPPER'.
Can you help me to learn more?
(Other definitions for dapper that I've seen before include "Neat and trim in dress" , "Neat and well-dressed" , "angler letting bait bob on water?" , "Smart; jaunty" , "Rakish" .)
