Kitty has new top (3)
I believe the answer is:
pot
'kitty' is the definition.
(both can mean a shared fund)
'new top' is the wordplay.
'new' indicates anagramming the letters.
'top' anagrammed gives 'POT'.
'has' is the link.
(Other definitions for pot that I've seen before include "Grass" , "Cannabis; sink (snooker)" , "Substance from the sap of trees" , "Slangy cannabis" , "Kitchen utensil or slang cannabis" .)
