In places, twisted part of fourth raw nugget (6)
I believe the answer is:
thrawn
'in places twisted part' is the definition.
I can't judge whether this defines the answer.
'of fourth raw nugget' is the wordplay.
'of' indicates a hidden word.
'THRAWN' can be found hidden inside 'fourth raw nugget'.
Can you help me to learn more?
(Other definitions for thrawn that I've seen before include "crooked up north?" , "perverse for a Scot" , "stubborn" .)
