Approach bankruptcy, abandoning one at university? (3-2)
I believe the answer is:
run-up
'approach' is the definition.
(I've seen this before)
'bankruptcy abandoning one at university?' is the wordplay.
'bankruptcy' becomes 'ruin' (I've seen this in another clue).
'abandoning' indicates named letters should be taken away.
'one' becomes 'i' (Roman numeral).
'at university?' becomes 'up' (slang term meaning at university).
'ruin' with 'i' taken out is 'run'.
'run'+'up'='RUN-UP'
(Other definitions for run-up that I've seen before include "Bowler's approach?" , "Cricketing approach?" , "Preliminary period" , "Approach - preliminaries" .)
