Many a timbered chamber is a convenient place for hats and coats (9)
I believe the answer is:
cloakroom
'many a timbered chamber is a convenient' is the definition.
I can't judge whether this defines the answer.
'place for hats and coats' is the wordplay.
I cannot really see how this works, but
'place' could be 'room' (I've seen this before) and 'room' is present in the answer.
The remaining letters 'cloak' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for cloakroom that I've seen before include "Euphemism for lavatory" , "Place to leave hats and coats" , "Room for outer garments" , "In which coats are left, temporarily" .)
