Etymology

It is borrowed from Ancient Greek κοσμικός (kosmikós, “of the world or universe”),[2][3][4][5] from κόσμος (kósmos, “order; the world”), the source of cosmos.[2][4][6] Etymonline takes it from a Latinized form of the Greek word.[3] The modern sense was borrowed in the 19th century from cosmique,[7] and the Shorter Oxford explains the word as formed on cosmos and -ic after the French.[8] The longer cosmical is older, from 1583.[7][3]

Earliest recorded meaning

Of this world, worldly: 1649, in John Ellistone's translation of Jakob Böhme's Epistles; this sense is obsolete.[2][3][7] Merriam-Webster dates the word to 1685.[6]

Semantic evolution

The modern sense, belonging to the universe as an ordered whole, appears in 1846 in George Grote's History of Greece;[2][7][3] from it came "universal, immense".[2][8] John Tyndall used cosmic in 1876 for what belongs to outer space as distinct from the earth, as in cosmic dust, and in 1879 for the vast scale of the universe.[2] Thomas Carlyle used it in 1858 for "orderly", the opposite of chaotic, a rare sense.[2] Cosmic rays is recorded from 1925, first in a paper by Robert Millikan in Nature.[2][7] In the slang of the psychedelic era, from 1967, cosmic meant excellent or overwhelming.[9]
