Makes small talk finally interesting with very large drinks (7)
I believe the answer is:
gossips
'makes small talk' is the definition.
Although both the answer and definition are verbs in their -s form, I cannot see how they can define each other.
'finally interesting with very large drinks' is the wordplay.
'finally' indicates one should take the final letters.
'with' says to put letters next to each other.
'very large' becomes 'os' (abbreviation for oversize).
'drinks' becomes 'sips' (sipping is a kind of drinking).
The final letter of 'interesting' is 'g'.
'g'+'os'+'sips'='GOSSIPS'
Can you help me to learn more?
(Other definitions for gossips that I've seen before include "They like talking about people's private lives" , "They love to talk about people's private lives" , "Tongue-waggers" .)
