Pronunciation

  • Classical: [tʰeˈoː.ri.a][1]
  • Ecclesiastical: [teˈɔː.ri.a][1]

Forms

theōria f (genitive theōriae); first declension[1]

Etymology

It is borrowed from Ancient Greek θεωρία (theōría, “a looking at, contemplation, speculation”).[1][2][3][4] Köbler connects the Greek noun with θεωρός (theōrós, “spectator, witness”) and θέα (théa, “a looking at”).[2]

Earliest recorded meaning

Cicero still wrote the word in Greek letters in a letter to Atticus.[4] As a Latin word it appears in Jerome's commentary on Ezekiel, meaning philosophical speculation or theory.[4][3][2]

Semantic evolution

In Late Latin it named philosophical speculation and inquiry, in Jerome, Ambrose, Augustine and Cassian.[5][6][7] The glossaries explain it with cōnsīderātiō and contemplātiō.[8]

In Medieval Latin it became above all a word for religious contemplation and meditation, especially of God,[9][10] and for a vision and the contemplative life;[9][2] a saint's life describes someone moving from the active life towards theoria.[11] English took theory in the 1590s from the Late Latin word.[12]
