Drag Harry around university (4)
I believe the answer is:
haul
'drag' is the definition.
(I know that drag can be written as haul)
'harry around university' is the wordplay.
'harry' becomes 'hal' (Hal can be a nickname for Harry or Henry).
'around' means one lot of letters goes inside another.
'university' becomes 'U' (abbreviation for university).
'hal' placed around 'u' is 'HAUL'.
(Other definitions for haul that I've seen before include "Spoils" , "Drag, with effort" , "Pull forcibly; catch" , "Drag (something heavy)" , "Pull with effort" .)
