Farms can't change for artisan (9)
I believe the answer is:
craftsman
'artisan' is the definition.
(synonyms)
'farms can't change' is the wordplay.
'change' indicates an anagram.
'farms'+'cant'='farmscant'
'farmscant' anagrammed gives 'CRAFTSMAN'.
'for' acts as a link.
(Other definitions for craftsman that I've seen before include "Artisan" , "Expert" , "Skilled worker" , "Carpenter, say" .)
