Pronunciation

  • Classical: [ka.teːˈkʰɪs.mʊs][1]
  • Ecclesiastical: [ka.teˈkiz.mus][1]

Forms

catēchismus m (genitive catēchismī); second declension[1] Medieval spellings include cathecismus, catezismus and catecismus.[2][3]

Etymology

It is borrowed from Ancient Greek κατηχισμός (katēkhismós, “instruction in the faith”),[4][3][2] a noun made from κατηχίζω (katēkhízō, “to catechize”), itself an extended form of κατηχέω (katēkhéō, “to instruct by word of mouth”).[1][3] Wiktionary marks the Greek noun as unattested.[1]

Earliest recorded meaning

Augustine uses it in De fide et operibus for elementary instruction in the Christian faith,[5][6][3] which Lewis & Short render as a catechism.[4]

Semantic evolution

In medieval Latin it was above all the preparation of candidates for baptism, by teaching and by rites,[2][7] and it was given even to newborn children before they were baptised.[8][2] From this it came to mean the basic teachings of the faith and a short compendium of them.[2][7] Ecclesiastical Latin uses it for a catechism.[9][10]

English catechism (c. 1500) comes from French catéchisme and directly from this Latin word.[11]

Timeline

  • 354–430 AD – Augustine uses it of elementary instruction in the faith.[4][5][3]
  • 1279 – An English synodal statute, spelling it cathacismus, uses it of what children receive between birth and full baptism.[7]
  • 1280 – The statutes of Bishop Auger II of Couserans use it for the instruction of newborn children before baptism.[8]
  • c. 1500 – English borrows it as catechism.[11]
  • 1549 – An English text defines it as a short instruction in common doctrine.[7]
