Cake supplied for opening a university? (6)
I believe the answer is:
gateau
'cake' is the definition.
(gateau is a kind of cake)
'opening a university?' is the wordplay.
'opening' becomes 'gate' (a gate is an opening or entrance).
'university?' becomes 'u' (abbreviation for university).
'gate'+'a'+'u'='GATEAU'
'supplied for' is the link.
This may not be correct. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for gateau that I've seen before include "Fancy cake" , "named for Black Forest?" , "Richly decorated cake" , "Something French for 22?" , "Creamy dessert cake" .)
