Origins

From Proto-Italic *klāssis, from Proto-Indo-European *klh₁-d⁽ʰ⁾-ti- (“a call”), from *kelh₁- (“to call, shout”). Cognate with Latin calō, clāmō, clārus, concilium, Ancient Greek καλέω (kaléō). De Vaan notes that simplification of the Proto-Italic *-ss- would be expected following long *-ā-. He suggests that, semantically, the term evolved from referring to a “calling out” to a “class of soldiers being called out” to a “social class.”
