Brand, say, having revised income need (10)
I believe the answer is:
comedienne
'brand say' is the definition.
Although both the answer and definition are singular nouns, I can't see how they can define each other.
'revised income need' is the wordplay.
'revised' is an anagram indicator.
'income'+'need'='incomeneed'
'incomeneed' anagrammed gives 'COMEDIENNE'.
'having' is the link.
Can you help me to learn more?
(Other definitions for comedienne that I've seen before include "Female humorist" , "Female comedy actor" , "Rivers perhaps" , "Funny female performer" , "stand-up entertainer?" .)
