We hear expressions of disapproval for alcohol (5)

I believe the answer is:

booze

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

'alcohol' is the definition.
(I know that alcohol can be written as booze)

I don't understand how the rest of the clue works.

Can you help me to learn more?

(Other definitions for booze that I've seen before include "Alcoholic drinks (colloq.)" , "Consume alcohol" , "plonk?" , "Intoxicating liquor" , "Drink to excess (colloq.)" .)

I've seen this clue in The Globe and Mail.
