Swedes are thus fixed to the spot (6)
I believe the answer is:
rooted
'fixed to the spot' is the definition.
(I've seen this before)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for rooted that I've seen before include "Fixed to the spot like a plant" , "Stuck in one place, like plant" , "Firmly attached as plants are to ground" , "Stuck to the spot" , "Firmly established in a plantlike way" .)
