Pronunciation

  • Classical: [ĩː.sʊˈɫaː.rɪs][1]
  • Ecclesiastical: [in.suˈlaː.ris][1]

Forms

īnsulāris (neuter īnsulāre); third-declension two-termination adjective[1]

Etymology

It is formed from Latin īnsula (“island”) + -āris.[1][2]

Earliest recorded meaning

The oldest instance is in Justin's epitome, which Köbler dates with a query to the 3rd century AD,[3] where the plural noun insulares is used of the keepers and inhabitants of a temple according to Lewis & Short and Gaffiot,[4][5] and of the occupants of a block of rented flats according to Georges.[6]

Semantic evolution

As an adjective, “of an island”, it is late: Lewis & Short label it post-classical,[4] and the TLL notes that Ammianus Marcellinus was fond of it.[2] Ammianus speaks of an island solitude and of the circuit of an island, as of the river that encloses the fort of the Parisii,[2][7] and with poena or supplicium of the punishment of banishment to an island: insulari poena multavit “he punished him with exile to an island”.[4][6][5]

Medieval writers in Britain used it for islands and their peoples, and as a noun for islanders, as the Scottish records do of the men of the Isles.[8] English took insular from it in the 17th century.[9]

Timeline

  • 3rd century AD – Justin uses the plural insulares for the keepers or inhabitants of a building (Köbler dates him with a query).[3][4][6]
  • c. 390 AD – Ammianus Marcellinus uses it as an adjective, “of an island”, and for banishment to an island.[3][4][2]
  • 1173 – Peter of Blois writes of all the island peoples (the DMLBS queries the date).[8]
  • 1310 – The Scottish rolls use insulares as a noun for islanders.[8]
  • 1610s – English borrows it as insular.[9]
