Try small drink making small talk (6)
I believe the answer is:
gossip
'small talk' is the definition.
(I know that small talk can be written as gossip)
'try small drink' is the wordplay.
'try' becomes 'go' (both can mean an attempt).
'small' becomes 's' (abbreviation - e.g. clothes size).
'drink' becomes 'sip' (sipping is a kind of drinking).
'go'+'s'+'sip'='GOSSIP'
'making' is the link.
(Other definitions for gossip that I've seen before include "Casual inaccurate talk about others" , "Tittle-tattle" , "Schmooze" , "Scandalous rumour" , "'Rumours, scandal (6)'" .)
