Feature that's intellectual in the East End (7)
I believe the answer is:
eyebrow
'feature' is the definition.
(I've seen this before)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for eyebrow that I've seen before include "What's raised in surprise" , "something going up doubtfully" , "this might be raised in surprise" , "Facial hair (that can be raised)" , "facial hair, for instance" .)
