Pronunciation

Forms

catēchizō (present infinitive catēchizāre, perfect active catēchizāvī, supine catēchizātum); first conjugation[1]

Etymology

It is borrowed from Ancient Greek κατηχίζω (katēkhízō), a Hellenistic variant of κατηχέω (katēkhéō, “to instruct orally; to instruct in religion”), which is made of κατά (katá, “down”) and ἠχή (ēkhḗ, “sound, noise”).[1][2]

Earliest recorded meaning

The TLL finds it from the Itala and Tertullian on, and never in the poets.[3] Tertullian asks whether someone who teaches about idols commits idolatry.[3][2]

Semantic evolution

In Christian Latin it meant to instruct, especially in the faith, and to teach by question and answer.[2][4] Augustine uses it of candidates being instructed before baptism, and Jerome, commenting on Galatians, distinguishes the one who is taught from the one who teaches.[3] Medieval writers used it for preparing someone for baptism and for instructing in the Christian faith.[5] The manuscripts spell it in many ways (-thec-, -tec-, -thez-, -tez-).[3]

English catechize comes from this Church Latin verb.[6]

Timeline

  • c. 160–220 AD – Tertullian uses it of teaching, in his treatise on idolatry and against Marcion.[3][2][7]
  • after 220 AD – The Itala, the Old Latin Bible, has it.[3][7]
  • 354–430 AD – Augustine uses it of instructing candidates for baptism.[3][7]
  • early 15th century – English borrows it as catechize.[6]
