Where students learn about where they can get cheap drinks? (5)
I believe the answer is:
union
'where they can get cheap drinks?' is the definition.
The answer is a location as well as being a singular noun. This is suggested by the definition.
'where students learn about' is the wordplay.
I cannot really understand how this works, but
'about' could be 'on' (as in a book 'on' a certain topic) and 'on' is present in the answer.
The remaining letters 'uni' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for union that I've seen before include "Workers' federation" , "mating" , "Association - guild" , "Equity, perhaps" , "Result of joining" .)
