Person putting clothes on cabinet (7)
I believe the answer is:
dresser
'cabinet' is the definition.
(I know that dresser is a type of cabinet)
'person putting clothes on' is the wordplay.
'person putting' becomes 'er' (I can't explain this - if you can you should give a lot more credence to this answer).
'clothes' becomes 'dress' (dress is a kind of clothes).
'on' is a charade indicator (letters next to each other).
'er' put after 'dress' is 'DRESSER'.
Can you help me to learn more?
(Other definitions for dresser that I've seen before include "Lady's maid" , "Theatre worker back-stage" , "One chiding" , "helps actor get ready" , "Chest of drawers" .)
