Describes one pulling heavy load that might have come down the chimney (7)
I believe the answer is:
draught
'pulling heavy load that might have come down the chimney' is the definition.
'draught' can be an answer for 'pulling' (draught is a kind of pulling). I'm unsure of the rest of the definition.
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for draught that I've seen before include "air moving" , "Dragging or pulling - man on board!" , "man that may be crowned" , "Dose of medicine" , "Too much air - not bottled" .)
