One in the chest? (6)
I believe the answer is:
drawer
'chest?' is the definition.
(thesaurus)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for drawer that I've seen before include "Sliding compartment in a chest" , "One providing cheque" , "Reward (anag.)" , "Box in chest - one sketching?" , "Person writing cheque" .)
