A university put in new chairs, causing ill-feeling? (10)
I believe the answer is:
nauseating
'causing ill-feeling?' is the definition.
(as in causing someone to feel ill)
'a university put in new chairs' is the wordplay.
'university' becomes 'u'.
'put in' is an insertion indicator.
'new' becomes 'n'.
'chairs' becomes 'seating' (I've seen this before).
'a'+'u'='au'
'n'+'seating'='nseating'
'au' placed inside 'nseating' is 'NAUSEATING'.
(Other definitions for nauseating that I've seen before include "being hard to keep down" , "arousing unpleasant feeling" , "Stomach-turning" , "Loathsome" , "Revolting" .)
