Pronunciation

Forms

intrīnsecus (not comparable)[1]

Etymology

It is an adverb formed from ⟨*intrim⟩, a form of inter (“between, among”), and secus2 (“alongside”), on the model of extrinsecus (“from outside”).[2][3][4] Georges and Lewis and Short give its first part as intrā (“within”),[5][6] and Wiktionary as ⟨inter⟩.[1] The grammarian Priscian already derived it from ⟨intrā⟩.[3]

Earliest recorded meaning

It is found first in Cato's De agricultura, meaning “on the inside”.[4][7][5]

Semantic evolution

Its main sense is “on the inside, internally”, as in Lucretius' throats black within, and Celsus' liver that is hollow inside and rounded outside.[6][5][4] Lewis and Short call it mostly ante-classical and post-Augustan.[6] It also meant “from within”, as in the Bellum Africum, where a commander attacks part of the enemy from the inside with his cavalry,[2][5] and “inwards”, as in Columella's vine shoots bent towards the inside.[2][4]

In Late Latin an adjective ⟨intrinsecus⟩ “inward” appears, first in Cassiodorus,[6][7] and in medieval Latin the adjective meant “internal, interior”, with its neuter used as a noun for the furniture of a house.[8] From the medieval adjective came English intrinsic, through Old French.[9]

  • c. 485–c. 580 AD – Cassiodorus uses the adjective intrinsecus “inward”.[6][7]
  • late 15th century – English takes intrinsic from the medieval adjective, through French.[9]
