Person who pretends to be another painter (13)
I believe the answer is:
impressionist
This could be a double definition.
'person who pretends to be another' is the first definition.
'impressionist' can be an answer for 'person' (impressionist is a kind of person). I'm unsure of the rest of the definition.
'painter' is the second definition.
(I know that impressionist is a type of painter)
Can you help me to learn more?
(Other definitions for impressionist that I've seen before include "Is he taking off" , "one good at doing copies?" , "One who takes off others" , "Mimic" , "artist?" .)
