Artist can rent dry studio at last (10)
I believe the answer is:
tintoretto
'artist' is the definition.
(I've seen this before)
'can rent dry studio at last' is the wordplay.
'can' becomes 'tin' ('tin' can be a synonym of 'can').
'rent' becomes 'tore' ('rend' and 'tear' both mean to rip something).
'dry' becomes 'tt' (abbreviation for teetotal).
'at last' suggests the final letters.
The final letter of 'studio' is 'o'.
'tin'+'tore'+'tt'+'o'='TINTORETTO'
(Other definitions for tintoretto that I've seen before include "16th century Italian painter" , "Italian painter, d. 1594" , "Artist" .)
