Maybe train as a skilled worker (7)
I believe the answer is:
artisan
'a skilled worker' is the definition.
(artisan is a kind of skilled worker)
'maybe train as' is the wordplay.
'maybe' indicates an anagram.
'train'+'as'='trainas'
'trainas' anagrammed gives 'ARTISAN'.
(Other definitions for artisan that I've seen before include "one in command of craft?" , "Skilled workman" , "Skilled manual 17" , "Skilled craftsperson" , "crafty person?" .)
