Closely examine watch at dinner-dance (7)
I believe the answer is:
eyeball
'closely examine' is the definition.
(I've seen this before)
'watch at dinner-dance' is the wordplay.
I cannot really see how this works, but
'watch' could be 'eye' (eye can mean to watch or look at) and 'eye' is located in the answer.
'dance' could be 'ball' (ball is a kind of dance) and 'ball' is present in the answer.
No letters remain.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for eyeball that I've seen before include "Confront (_____ to _____)" , "It was cut in Un Chien Andalou" , "pupil found here" , "Look confrontationally" , "Ocular orb" .)
