Trendy universities working together (2,6)
I believe the answer is:
in unison
'together' is the definition.
(I've seen this before)
'trendy universities working' is the wordplay.
'trendy' becomes 'in' ('in' can mean fashionable).
'universities working' becomes 'unison' (I can't explain this - if you can you should give a lot more credence to this answer).
'in'+'unison'='IN UNISON'
Can you help me to learn more?
(Other definitions for in unison that I've seen before include "All together at the same pitch" , "All speaking or singing as one" , "All speaking or singing at the same time" , "All singing the same notes" , "Simultaneously" .)
