Click disapprovingly at university skirt (4)
I believe the answer is:
tutu
'skirt' is the definition.
(I know that tutu is a type of skirt)
'click disapprovingly at university' is the wordplay.
'click disapprovingly' becomes 'tut' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'at' means one lot of letters go next to another.
'university' becomes 'u' (abbreviation for university).
'tut'+'u'='TUTU'
Can you help me to learn more?
(Other definitions for tutu that I've seen before include "Ballet dancer's costume" , "Ballet-dancer's skirt" , "very short garment" , "In which dancer may appear" , "Giselle's skirt" .)
