Crude burrow close to spinney (6)
I believe the answer is:
earthy
'crude' is the definition.
(both can mean vulgar)
'burrow close to spinney' is the wordplay.
'burrow' becomes 'earth' (I've seen this before).
'close to' says to take the final letters (the 'close' to the word).
The final letter of 'spinney' is 'y'.
'earth'+'y'='EARTHY'
(Other definitions for earthy that I've seen before include "Suggestive of soil" , "Hearty and lusty" , "Natural" , "Resembling soil" , "where we live" .)
