Not a good look from these vile yeomen (4,3)
I believe the answer is:
evil eye
'not a good look' is the definition.
I can't judge whether this defines the answer.
'from these vile yeomen' is the wordplay.
'from' says the answer is hidden in the clue.
'EVIL-EYE' is hidden in the letters of 'these vile yeomen'.
Can you help me to learn more?
(Other definitions for evil eye that I've seen before include "Look or glance supposed to cause harm" , "Look superstitiously believed to cause harm" , "Depraved optic with superstitious curse" , "Supposedly harmful stare" , "Gaze or stare believed to cause harm" .)
