Mae West's sheepish part in film is seen (6)
I believe the answer is:
viewed
'is seen' is the definition.
(I've seen this in another clue)
'mae west's sheepish part in film' is the wordplay.
I cannot quite understand how this works, but
'part' could be 'view' (view is a kind of part) and 'view' is found within the answer.
The remaining letters 'ed' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for viewed that I've seen before include "Looked at, inspected" , "Saw" , "Observed" , "Considered or deemed to be" , "Considered or looked at" .)
