So he knows a fair number of languages thoroughly in the films, and it's said he can speak 27 in the YIJC--which given his fluency in languages in the Ford films does seem believable, though he may have gotten rusty with some over time.
Dont forget, he also could speak German, When he was posing as a butler in LC on the Zeppelin.
