Dancing around, aren’t I a bit of a looker? (6)
I believe the answer is:
retina
'a bit of a looker?' is the definition.
(part of an eye, something which looks)
'dancing around aren't i' is the wordplay.
'aren't i' anagrams to 'RETINA'.
However, I am unsure how the anagram is indicated.
Can you help me to learn more?
(Other definitions for retina that I've seen before include "What's behind the humour" , "part of the water pump" , "Light-sensitive eye layer" , "Sensitive part of eye" , "Part of the eyeball" .)
