Ideal university head, above Scotsman (7)
I believe the answer is:
utopian
'ideal' is the definition.
('utopian' can be similar in meaning to 'ideal')
'university head above scotsman' is the wordplay.
'university' becomes 'u'.
'head' becomes 'top' ('top' can be a synonym of 'head'**).
'above' is a charade indicator (letters next to each other).
'scotsman' becomes 'ian'.
'u'+'top'+'ian'='UTOPIAN'
(Other definitions for utopian that I've seen before include "Idealistic but usually impractical" , "Really ideal in perfect fictional country" , "Ideal; imaginary" , "Too perfect for this world" , "in a dreamy state" .)
