List of options for fellows at university (4)
I believe the answer is:
menu
'list of options' is the definition.
(I've seen this in another clue)
'fellows at university' is the wordplay.
'fellows' becomes 'men' (fellow can mean a man).
'at' means one lot of letters go next to another.
'university' becomes 'u' (abbreviation for university).
'men'+'u'='MENU'
'for' acts as a link.
(Other definitions for menu that I've seen before include "Options available" , "List of available food and drink" , "that can appear on computer screen" , "List of options" , "Tariff" .)
