Ill-bred university lecturer embraces endless twisted debauchery (7)
I believe the answer is:
uncivil
'ill-bred' is the definition.
(thesaurus)
'university lecturer embraces endless twisted debauchery' is the wordplay.
'university' becomes 'uni' (informal abbreviation).
'lecturer' becomes 'l' (abbreviation for lecturer).
'embraces' is an insertion indicator.
'endless twisted debauchery' becomes 'civ' (I can't justify this - if you can you should give a lot more credence to this answer).
'uni'+'l'='unil'
'unil' going around 'civ' is 'UNCIVIL'.
Can you help me to learn more?
(Other definitions for uncivil that I've seen before include "Not polite or mannered" , "Curt" , "Impolite" , "Not polite, discourteous" , "Not polite or obliging" .)
