Artist with his own piece of land in outer Surrey (6)
I believe the answer is:
sisley
'artist with his own piece' is the definition.
I know nothing about this answer so I cannot tell whether it can be defined by this definition.
'land in outer surrey' is the wordplay.
'land' becomes 'isle' (isle is a kind of land).
'in' is an insertion indicator.
'outer' says to hollow out the word (remove centre letters).
'surrey' with its centre taken out is 'sy'.
'isle' put within 'sy' is 'SISLEY'.
'of' acts as a link.
Can you help me to learn more?
(Other definitions for sisley that I've seen before include "French Impressionist painter of English descent, d. 1899" , "Impressionist painter of British nationality, d. 1899" .)
