Drink of which disapproving cries are heard (5)
I believe the answer is:
'drink of' is the definition.
'booze' can be an answer for 'drink' (synonyms). I'm not sure about the 'of' bit.
'disapproving cries are heard' is the wordplay.
'disapproving' becomes 'b' (I can't explain this - if you can you should believe this answer much more).
'cries' becomes 'oohs' ('ooh' is an exclamation or cry).
'are heard' indicates a 'sounds like' (homophone) clue.
'oohs' is a homophone of 'ooze'.
'which' is the link.
Can you help me to learn more?
(Other definitions for booze that I've seen before include "Alcoholic liquor" , "Consume alcohol" , "Intoxicating liquor" , "intoxicating stuff" , "Drink to excess (colloq.)" .)
