Lecturer, jolly, repeated character coming to the fore being lewdness (7)
I believe the answer is:
lechery
'lewdness' is the definition.
(thesaurus)
'lecturer jolly repeated character coming to the fore' is the wordplay.
'lecturer' becomes 'l' (abbreviation for lecturer).
'jolly repeated' becomes 'chery' (I am not sure about this - if you are sure you should believe this answer much more).
'character' becomes 'e'.
'coming to the fore' says to put letters next to each other.
'chery' put after 'e' is 'echery'.
'l'+'echery'='LECHERY'
'being' acts as a link.
Can you help me to learn more?
(Other definitions for lechery that I've seen before include "Excessive sexual desire" , "Unrestrained sexual desire" , "lustfulness" .)
