Moue (7)
I believe the answer is:
grimace
'moue' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for grimace that I've seen before include "unpleasant expression" , "Contortion of face expressing pain" , "Glower" , "Facial expression showing disgust, wry humour etc" , "Disgusted expression" .)
