Pronunciation

  • IPA (Classical): [skiˈɛn.ti.a][1]
  • IPA (Ecclesiastical): [ʃiˈɛn.t͡si.a][1]

Forms

scientia f (genitive scientiae); first declension[1]

Etymology

It is from Latin sciēns (“knowing”) + -ia, from sciō “to know”.[2][1][3] De Vaan takes scio as a back-formation from nesciō, perhaps from a root meaning “to cut, distinguish”, Proto-Italic *skije/o-, Proto-Indo-European *skh₁-i(e/o)-.[3]

Earliest recorded meaning

It is found from Varro onwards,[3][1] who says the physician Hippocrates saved many towns by his knowledge.[2]

Semantic evolution

It meant knowledge of a fact or situation, as in Cicero, expert understanding of an art or science, and learning or erudition.[2][1] In philosophy it rendered Greek ἐπιστήμη, knowledge as opposed to belief.[1]

In Medieval Latin it was a science, an organised branch of knowledge, and in logic knowledge from cause to effect.[1] English science came from it through Old French in the mid-14th century.[4]

Timeline

  • 116–27 BC – Varro uses it of medical knowledge.[2][5]
  • 81–43 BC – Cicero uses it of knowledge and learning.[2][5]
  • mid-14th century – English science is recorded.[4]
