It's another way to sit in an artist's studio (3)
I believe the answer is:
tis
'sit in an artist's studio' is the definition.
I can't tell whether this defines the answer.
'it's another way' is the wordplay.
'another' indicates an anagram.
'way' becomes 's' (Compass direction - South).
'it' with letters rearranged gives 'ti'.
'ti'+'s'='TIS'
'to' is the link.
Can you help me to learn more?
(Other definitions for tis that I've seen before include "I confirm the identity of" , "Contraction of it is" , "McCourt work" , "For poet, that's" , "... the season to be jolly" .)
