Emphasise insulting comment about Kitty (9)
I believe the answer is:
spotlight
'emphasise' is the definition.
(I know that spotlight is a more specific form of the action bring out)
'insulting comment about kitty' is the wordplay.
'insulting comment' becomes 'slight' (I am not sure about this - if you are sure you should believe this answer much more).
'about' indicates putting letters inside.
'kitty' becomes 'pot' (both can mean a shared fund).
'slight' enclosing 'pot' is 'SPOTLIGHT'.
Can you help me to learn more?
(Other definitions for spotlight that I've seen before include "Beam directed on small area or on stage performer" , "It illuminates a small area" , "Direct attention to" , "Lit up in public here" , "Focus" .)
