Where does cosmos come from?
From Middle English cossmos (“the universe; the world”), borrowed from Ancient Greek κόσμος (kósmos, “order; universe; the earth, the world; decoration, ornament”), ultimately from Proto-Indo-European *ḱens- (“to announce, proclaim; to put in order”). The plural form cosmoi is a learned borrowing from Ancient Greek κόσμοι (kósmoi).
