Artist making visit, hugging old woman (7)
I believe the answer is:
chagall
'artist' is the definition.
(painter Marc Chagall)
'visit hugging old woman' is the wordplay.
'visit' becomes 'call' (synonyms).
'hugging' means one lot of letters goes inside another.
'old woman' becomes 'hag' (hag is a kind of old woman).
'call' placed around 'hag' is 'CHAGALL'.
'making' is the link.
(Other definitions for chagall that I've seen before include "Marc --, Russian-French artist" , "Marc -, twentieth century Russian-born French artist" , "He painted" , "Marc --, Russian artist" , "Russian-born painter" .)
