Pronunciation

  • IPA (Classical): [ˈrɛ.ɡi.oː][1]
  • IPA (Ecclesiastical): [ˈrɛː.d͡ʒi.o][1]

Forms

regiō f (genitive regiōnis); third declension[1]

Etymology

It is from Latin regō (“to direct, guide”) + -iō.[2][3] The verb is inherited from Proto-Italic *reg-e/o-, inherited from Proto-Indo-European *h₃reǵ-e/o- (“to stretch, direct”).[4]

Earliest recorded meaning

De Vaan dates it from Plautus,[4] who asks in what district a son bought a house.[2] Köbler dates Plautus c. 250–184 BC.[5]

Semantic evolution

Its basic sense was a direction or line, as in rēctā regiōne “in a straight line” and ē regiōne “opposite”.[2][6][1] It also meant relative position, geographical situation and a boundary line, especially the lines marking out the sky in augury.[2] From this it came to mean a part of a larger area, a district or region, a region of the sky or of the body, and figuratively a field of thought or activity.[2] Döderlein contrasts regiō, a space seen as a circle, with locus, a single point, and tractus, a line.[7]

Isidore derived it from rēctōrēs, governors.[3] In medieval Latin it was a kingdom, the district of a city, a county and a principality.[8] It survives in Italian rione (“district of a city”), and was borrowed as French région; English region is recorded about 1300.[1][9]
