Viewers' vowels annunciated (4)
I believe the answer is:
eyes
'viewers'' is the definition.
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for eyes that I've seen before include "private detectives" , "Spots on a peacock's tail" , "Poetically, they're the windows of the soul" , "Paradoxical title of 1999 Kubrick film" , "They see and" .)
