Nova Scotia hip according to this nut (9)
I believe the answer is:
pistachio
'this nut' is the definition.
(pistachio is a kind of nut)
'nova scotia hip according' is the wordplay.
'scotia hip' anagrams to 'PISTACHIO'.
Though, I am unsure how this is indicated.
'to' is the link.
Can you help me to learn more?
(Other definitions for pistachio that I've seen before include "nut-bearing tree" , "Yellowish-green" , "Green nut" , "Small sweet-tasting nut" , "Nut tree" .)
