It's much taller, said Spooner, getting confused (7)
I believe the answer is:
haywire
'confused' is the definition.
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for haywire that I've seen before include "nuts" , "Disorganised" , "Not working properly" , "Chaotic" , "Erratic, out of control" .)
