Move restlessly around the capital of Norway, causing spite (5)
I believe the answer is:
venom
'spite' is the definition.
(I know this)
'move restlessly around the capital of norway' is the wordplay.
'restlessly' indicates an anagram (I've seen this in other clues).
'around' indicates putting letters inside.
'the capital of' suggests taking the first letters.
The initial letter of 'norway' is 'n'.
'move' with letters rearranged gives 'veom'.
'veom' placed around 'n' is 'VENOM'.
'causing' acts as a link.
(Other definitions for venom that I've seen before include "Poisonous liquid of snakes" , "Bitter malice" , "acrimony" , "Virulence" , "Virulent feeling" .)
