Director of 'Argo'? (6)
I believe the answer is:
tiller
'director' is the definition.
Although both the answer and definition are singular nouns, I don't see how one could define the other.
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for tiller that I've seen before include "Boat steerer" , "Worker on the land found on board" , "Farmer" , "Steering lever" , "Handle for turning rudder" .)
