The story
- Old Occitan · derived fromchuadit
- English todayShuadit
Coined by Zosa Szajkowski, who believed it to be derived from Hebrew יְהוּדִית (y'hudít, “Jewish [language]”), although this has shown to be spurious. The word that he based it on was in fact from Old Occitan chuadit, a manuscript variant of chuadi in a poem written by a non-Jew, and is of unclear meaning.
