Inciter of revels sins terribly, with you on date (8)
I believe the answer is:
dionysus
'inciter of revels' is the definition.
The definition and answer can be both people as well as being singular nouns.
Perhaps there's an association between them I don't understand?
'sins terribly with you on date' is the wordplay.
'terribly with' indicates anagramming the letters.
'on' is a charade indicator (letters next to each other).
'date' becomes 'd' (common abbreviation eg in DOB, date of birth).
'sins' mixed up with 'you' gives 'ionysus'.
'ionysus' put after 'd' is 'DIONYSUS'.
Can you help me to learn more?
(Other definitions for dionysus that I've seen before include "Greek god of wine and good times" , "Wine-god" , "Greek god (Bacchus is his Roman equivalent)" , "Greek god of wine and fertility, also known as Bacchus" , "Sins you'd associate with Greek god of wine and fertility" .)
