Sweetheart hypothetically, in part, crude (6)

I believe the answer is:

earthy

'crude' is the definition.
(thesaurus)

'sweetheart hypothetically in part' is the wordplay.
'in part' indicates a hidden word.
'EARTHY' can be found hidden inside 'sweetheart hypothetically'.

(Other definitions for earthy that I've seen before include "Dirty" , "Vulgar, of the soil" , "Natural" , "Head covering" , "Lusty, coarse" .)

I've seen this clue in The Times.
