Jewish artist needs tea and chutzpah (7)
I believe the answer is:
chagall
'jewish artist' is the definition.
(Marc Chagall)
'tea and chutzpah' is the wordplay.
'tea' becomes 'cha' (cha is a type of tea).
'and' says to put letters next to each other.
'chutzpah' becomes 'gall'.
'cha'+'gall'='CHAGALL'
'needs' acts as a link.
(Other definitions for chagall that I've seen before include "Marc --, Russian-French artist" , "Russian-born painter" , "He painted" , "Marc --, Russian artist" , "Marc -, twentieth century Russian-born French artist" .)
