Pronunciation

  • Classical: [a.pɔ.ɫɔˈɡeː.tɪ.kʊs][1]
  • Ecclesiastical: [a.po.loˈd͡ʒɛː.ti.kus][1]

Forms

apologēticus (feminine apologētica, neuter apologēticum); first/second-declension adjective[1]

Etymology

It is borrowed from Ancient Greek ἀπολογητικός (apologētikós, “suitable for a defence”).[1][2][3][4] Conte classes it as a Late Latin word.[5]

Earliest recorded meaning

The word first appears as the title of Tertullian's defence of Christianity, the Apologeticum (or Apologeticus, understood as liber, “book”).[2][5][6] Lactantius refers to the book “to which the name Apologeticum is given”.[7]

Semantic evolution

As an adjective it meant serving to defend or justify, and Rufinus already uses it so.[5][3] Isidore of Seville defines an apologeticum as an excuse, the kind of text in which one answers one's accusers.[7]

Medieval writers used the adjective of words and letters written in someone's defence, and the noun for a written defence or apology, especially of the orthodox faith.[3][4] Aldhelm speaks of the defending truth of words, and Alcuin of letters containing a defence.[4] An Old English gloss renders it beladung.[4] Humanists such as Manetti and Petrarch still used it, Manetti as the title of his defence against his detractors.[8] English took it over in the 1640s, through French.[9]
