microcosm

Etymology and origin of the English word microcosm

History

Pronunciation

  • IPA: /ˈmaɪ.kɹə(ʊ)ˌkɒz.əm/ (UK); /ˈmaɪ.kɹəˌkɑz.əm/ (US)[1]

Etymology

It is inherited from Middle English microcosme,[2][3] borrowed from Middle French microcosme,[2][3] from Medieval Latin microcosmus,[2][3][4][5] from Ancient Greek μικρὸς κόσμος (mikròs kósmos, “little world”) (see micro- and cosmos).[2][3][4][5][6] An earlier Middle English form, microcosmos, was borrowed directly from Medieval Latin about 1200.[3][4][7]

Earliest recorded meaning

Human nature, man viewed as an epitome of the great world or universe (c. 1200 in the OED; late 12th century in Etymonline, in the Ormulum as mycrocossmos).[7][4][3]

Semantic evolution

Philosophers applied the “little world” metaphorically to the human frame, and it became a favourite medieval word for “man”.[4][6] The Ormulum (c. 1175) explains that in English it means “the little world”, and Old English glossaries render it læsse middangeard.[4] The modern form dates from the early 15th century.[4][3] From 1562 the word was applied to a community or other complex unity regarded as an epitome of the world,[7][4] and later to anything regarded as a world in miniature.[8][6] In alchemy it once meant the philosopher's stone (1477).[7] Its opposite is macrocosm.[6][1]
