You're right, but what does it say about Germans when they have to borrow the word "small talk"?
You'd have me convinced, except that I have it on the assurances of a fine former US president that the French, in fact, have no word for entrepreneur.
It's a class thing.
Never mind that there are quite a few words for small talk, too. As if that's the only word in English for it... It's just that it got quite popular due to its poignancy. Just like "Zeitgeist" the other way 'round.
