Number of ladies drink (4)
I believe the answer is:
bevy
This clue could be a double definition.
'number of' is the first definition.
'bevy' can be an answer for 'number' (thesaurus). I am not sure about the 'of' bit.
'drink' is the second definition.
(short for beverage)
'ladies' acts as a link.
Can you help me to learn more?
(Other definitions for bevy that I've seen before include "Flock of larks; group of beautiful women" , "many girls" , "Gaggle" , "Pack" , "Many women" .)
