A simple model? (6)
I believe the answer is:
sitter
This might be a double definition.
'a simple' is the first definition.
The definition and answer can be both people as well as being singular nouns.
Maybe there's a link between them I don't understand?
'model?' is the second definition.
(I've seen this before)
Can you help me to learn more?
(Other definitions for sitter that I've seen before include "One posing for artist" , "Artist's model - an easy catch" , "A poser" , "one can't stand?" , "Model - childminder" .)
