Vertigo surprises (8)
I believe the answer is:
staggers
'vertigo surprises' is the definition.
The answer and definition can be both acts as well as being plural nouns.
Perhaps they are linked in a way I don't understand?
This is all the clue.
Can you help me to learn more?
(Other definitions for staggers that I've seen before include "Reels about like gagsters" , "astounds" , "Reels from side to side" , "Disease affecting farmyard animals" , "causes amazement" .)
