In French, starboard and port are "tribord" (same etymology as "starboard", through Dutch) and "bâbord" ("back (of the oarman) board").
On stage, they are "côté cour" and "côté jardin" because the "Comédie-Française" theatre during the 1770 was in the Tuileries palace, and the stage was oriented with the Louvre courtyard on its right, and the Tuileries garden on its left.
