Use French when no translation
Fragment of a discussion from Portal talk:Oc/LiquidThreads
No way. For linguistical closeness reasons, Catalan is a much better choice.
Written Catalan is much closer to written Occitan than for instance Czech to Slovak or Upper Sorbian to Lower Sorbian. Until 1934 most Catalan scholars considered Catalan as a dialect of Occitan.
Right, but ideally we'd have some intelligibility study as the very accurate one we used for Czech and Slovak. Anyway, I've opened a separate discussion for this option: Thread:Portal talk:Ca/Joining forces with Occitan.
