plateau

'flat' is the definition.
(thesaurus)

'ground serving a university' is the wordplay.
'ground serving' becomes 'plate' (I am not sure about the 'ground' bit.).
'university' becomes 'u' (abbreviation for university).
'plate'+'a'+'u'='PLATEAU'

Can you help me to learn more?

(Other definitions for plateau that I've seen before include "Tract of tableland" , "Reach a level" , "Elevated flatland" , "High tableland" , "somewhere flatter?" .)
