Wicked home with time for witty conversation (8)
I believe the answer is:
badinage
'witty conversation' is the definition.
(I've seen this before)
'wicked home with time for' is the wordplay.
'wicked' becomes 'bad' ('bad' can be similar in meaning to 'wicked').
'home' becomes 'in' ('he's home' can mean 'he's in').
'with' says to put letters next to each other.
'time for' becomes 'age' (I've seen this in other clues).
'bad'+'in'+'age'='BADINAGE'
(Other definitions for badinage that I've seen before include "Frivolous repartee" , "bit of playful repartee" , "Good-natured banter or teasing" , "Drollery" , "Teasing talk, banter" .)
