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]
