Slim movie director (4)
I believe the answer is:
lean
This might be a double definition.
'slim' is the first definition.
(similar in meaning)
'movie director' is the second definition.
Although both the answer and definition are singular nouns, I don't understand how one could define the other.
Can you help me to learn more?
(Other definitions for lean that I've seen before include "What Jack Sprat's wife couldn't eat" , "bank" , "Meagre" , "David ..., director of Ryan's Daughter" , "Thin; rest (against)" .)
