Consumers make loud noises when imbibing half of beer (6)
I believe the answer is:
diners
'consumers' is the definition.
(diner is a kind of consumer)
'noises when imbibing half of beer' is the wordplay.
'noises when' becomes 'dins' (din is a kind of noise. I am not sure about the 'when' bit.).
'imbibing' is an insertion indicator (imbibe can mean to drink or absorb).
'half of' means to take half the letters.
'beer' cut in half is 'er'.
'dins' placed around 'er' is 'DINERS'.
'make loud' is the link.
This may not be right. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for diners that I've seen before include "Eaters of a meal" , "Restaurants" .)
