+definition cosmo
Cosmos. In the general sense, a cosmos is an orderly or harmonious system. The word derives from the Greek term ÎºÏÏÎ¼Î¿Ï, literally meaning order or ornament and metaphorically world, and is antithetical to the concept of chaos. Today, the word is generally used as a synonym of the Latin loanword Universe. The word cosmetics originates from the same root.
