Czardas is a slight alteration of Hungarian csárdás, from csárda “wayside tavern, inn.” Csárdás comes from Persian chārtāk, “four-cornered room,” in which the chār- element, meaning “four,” is a distant relative of English four, Latin quattuor, and Ancient Greek tésseres, as in the Word of the Day tessellate. Czardas was first recorded in English in the late 1850s.
