Crude, primitive art, hyped somewhat (6)
I believe the answer is:
earthy
'crude' is the definition.
(both can mean vulgar)
'primitive art hyped somewhat' is the wordplay.
'somewhat' indicates the answer is hidden within the clue.
'EARTHY' can be found hidden inside 'primitive art hyped'.
(Other definitions for earthy that I've seen before include "where we live" , "Unenthusiastic" , "Consisting of soil" , "Resembling soil" , "Coarse like the soil" .)
