Puzzle, being crazy to get into a popular drink (8)
I believe the answer is:
bewilder
'puzzle' is the definition.
(I know that puzzle can be written as bewilder)
'crazy to get into a popular drink' is the wordplay.
'crazy' becomes 'wild' (I've seen this in another clue).
'to get into' is an insertion indicator.
'a popular drink' becomes 'beer' (beer is a kind of drink. I am not sure about the 'popular' bit.).
'wild' inserted inside 'beer' is 'BEWILDER'.
'being' is the link.
Can you help me to learn more?
(Other definitions for bewilder that I've seen before include "Confuse - perplex" , "fox" , "Perplex the wild beer" , "Wild beer tending to confuse" , "Confuse utterly" .)
