Repartee from ten, drunk in pub (6)
I believe the answer is:
banter
'repartee' is the definition.
(I know that banter is a type of repartee)
'ten drunk in pub' is the wordplay.
'drunk' is an anagram indicator.
'in' means one lot of letters goes inside another.
'pub' becomes 'bar' (both are drinking establishments).
'ten' anagrammed gives 'nte'.
'nte' inserted inside 'bar' is 'BANTER'.
'from' is the link.
(Other definitions for banter that I've seen before include "Light-hearted chaff or teasing" , "Friendly teasing talk" , "Teasing remarks of good-humoured kind" , "Light teasing repartee" , "(Witty?) chat" .)
