bewilder

I'm a little stuck... Click here to teach me more about this clue!

'to confuse' is the definition.
(I know that bewilder is a more specific form of the action bedevil)

I don't understand the remainder of the clue.

Can you help me to learn more?

(Other definitions for bewilder that I've seen before include "Confuse utterly" , "Confuse totally" , "Perplex the wild beer" , "Nonplus" , "Wild beer tending to confuse" .)

I've seen this clue in The Daily Express.
