Sod taking some from Uncle Arthur (5)
I believe the answer is:
earth
'sod' is the definition.
(thesaurus)
'some from uncle arthur' is the wordplay.
'some from' says the answer is hidden in the clue.
'EARTH' is hidden in the letters of 'uncle arthur'.
'taking' is the link.
(Other definitions for earth that I've seen before include "costs so much?" , "Connection between an electrical device and conductor" , "dirt" , "Terra firma" , "Badger or fox burrow" .)
