University student rushes around outside being profane (7)
I believe the answer is:
secular
'being profane' is the definition.
('secular' can be similar in meaning to 'profane')
'university student rushes around outside' is the wordplay.
'university' becomes 'U' (abbreviation for university).
'student' becomes 'l' (as in L-plates for learner drivers).
'rushes' becomes 'races' ('race' can be a synonym of 'rush').
'around' is a reversal indicator.
'outside' indicates putting letters inside.
'races' in reverse letter order is 'secar'.
'u'+'l'='ul'
'ul' going within 'secar' is 'SECULAR'.
(Other definitions for secular that I've seen before include "Profane" , "Ignoring God" , "without religion" , "Not involving religion,worldly" , "associated with those who are 21 [LAYMEN]" .)
