Forms

κόσμος (kósmos) m (genitive κόσμου); second declension[1]

Etymology

It is inherited from Proto-Hellenic *kónsmos,[1] inherited from Proto-Indo-European *ḱónsmos, a noun in -μος from the root *ḱens- (“to announce, put in order”).[1][2] Beekes considers *ḱoNs-mo- the most probable reconstruction; it makes the word a relative of Latin cēnseō (“to assess, estimate”) and Sanskrit शंसति (śaṃsati, “to praise”), and the original meaning would have been “to put in order by speaking”, with “to adorn” a later development within Greek.[2][1] Within Greek it may be related to κέκασμαι (kékasmai, “to excel”).[3][2]

Frisk found none of the many proposals satisfactory: others had connected it with κεδνός (kednós, “careful, trusty”), with Latin corpus or with κομψός (kompsós, “refined”).[4][5]

Earliest recorded meaning

Homer uses it for order and for ornament: κατὰ κόσμον means “duly, properly”, and οὐ κατὰ κόσμον “in an unseemly way”.[6][7] It is also an ornament for a horse and a woman's dress, and in the Odyssey the “making” of the wooden horse.[6][8]

Semantic evolution

In Classical Greek it is order of every kind: the order of troops (fleeing “in no order”), good behaviour and discipline, and the order of a state, its constitution or government, as the Spartan constitution in Herodotus or the oligarchy in Thucydides.[7][8] The sense “ornament” continued, of dress, of equipment, and in rhetoric of the ornaments of speech in Isocrates and Aristotle.[7][8] It could also mean honour or credit: in Sophocles, “silence is a woman's ornament”.[7] In Crete the chief magistrates were called κόσμοι.[7][2]

In philosophy it became the ordered world, the universe, first with Pythagoras or Parmenides.[7][2] Heraclitus says that “this cosmos” was made by no god or man, but always was, is and will be fire.[7] Xenophon still speaks of “what the sophists call the cosmos”, but in Plato and Aristotle it is the normal term, and Epicurus speaks of many worlds.[7]

In Koine it came to mean the world of men: the Septuagint uses it for the universe, the earth, mankind and ornament,[9] and the New Testament for adornment, for the inhabited earth, for the way of the world, and for people estranged from God, as in “what does it profit a man to gain the whole world?”[10][11][5]

Medieval vernacular Greek used it for an ornament, the universe, the earth or a country, mankind, and a crowd of people.[12] Modern Greek κόσμος (kósmos) is the universe, the world and also people, society; some senses follow French monde.[13][5] English cosmos is recorded c. 1200, but became popular only after 1848, as the equivalent of Humboldt's Kosmos.[14]
