Cheek, and other facial feature (3)
I believe the answer is:
lip
This might be a double definition.
'cheek' is the first definition.
(lip is a kind of cheek)
'facial feature' is the second definition.
'and other' is the link.
This may not be correct. Some or all of it may belong to one of the definitions.
(Other definitions for lip that I've seen before include "sauciness" , "Part of mouth or cheek" , "Insolence (slang)" , "Brink" , "giving such insincere service" .)
