Free love repeatedly found in university (5)
I believe the answer is:
loose
'free' is the definition.
(I know that free can be written as loose)
'love repeatedly found in university' is the wordplay.
'love' becomes 'o' (love means zero in tennis).
'repeatedly' indicates the doubling of some letters.
'found in' indicates putting letters inside.
'university' becomes 'lse' (London School of Economics).
'o' doubled is 'oo'.
'oo' put within 'lse' is 'LOOSE'.
(Other definitions for loose that I've seen before include "Untie; dissolute" , "Not tightly fixed" , "Unrestrained" , "Imprecise" , "Slack or immoral" .)
