Word seen at the end of many Jean-Luc Godard movies (3)

I believe the answer is:

fin

(Other definitions for fin that I've seen before include "Thin projection for fish to steer itself" , "Fish propeller; end (Fr.)" , "Fishy appendage" , "Piscine appendage" , "Paddle-like organ" .)

I've seen this clue in The New York Times.
