One sketches naked, finally, comparatively bare (6)
I believe the answer is:
drawer
'one sketches' is the definition.
(someone who sketches)
'naked finally comparatively bare' is the wordplay.
I cannot really understand how this works, but
'naked' could be 'raw' (I've seen this in other clues) and 'raw' is located in the answer.
The remaining letters 'der' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for drawer that I've seen before include "Box-like container that slides" , "Sliding storage box" , "One providing cheque" , "One taking out money" , "Reward (anag.)" .)
