Gossip with Jean-Paul Sartre’s feline friend? (4)
I believe the answer is:
chat
I believe this clue is a double definition.
'gossip' is the first definition.
(I know that gossip can be written as chat)
'jean-paul sartre's feline friend?' is the second definition.
('cat' in French - Jean-Paul Sartre was French)
'with' acts as a link.
(Other definitions for chat that I've seen before include "Talk informally; bird" , "flier" , "tittle-tattle" , "Talking" , "Talk familiarly" .)
