Is she less than an eyeful? (4)
I believe the answer is:
iris
'is she' is the definition.
(I've seen this before)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for iris that I've seen before include "Fleur-de-lis" , "Film about writer _______ Murdoch" , "--- Murdoch, author" , "Flowers in the eye?" , "Lily" .)
