Cap is manufactured thus for artist (7)
I believe the answer is:
'for artist' is the definition.
(Picasso is an example)
'cap is manufactured thus' is the wordplay.
'manufactured' indicates anagramming the letters.
'thus' becomes 'so' (synonyms).
'capis' anagrammed gives 'picas'.
(Other definitions for picasso that I've seen before include "Cubist artist" , "Pablo -, Spanish painter/sculptor" , "As cop is a Spanish painter" , "Spanish artist who emigrated to France, d. 1973" , "So aspic is out for the Spanish artist" .)
