Pronunciation

  • Classical: [hɔsˈtiː.lɪs][1]
  • Ecclesiastical: [osˈtiː.lis][1]

Forms

hostīlis (neuter hostīle, adverb hostīliter); third-declension two-termination adjective[1]

Etymology

It is formed from Latin hostis (“enemy”) + -īlis, like cīvīlis from cīvis.[2][3][1] De Vaan traces hostis to Proto-Italic *χosti- and Proto-Indo-European *gʰosti- (“stranger, guest”), cognate with Gothic 𐌲𐌰𐍃𐍄𐍃 (gasts, “guest”) and Old Church Slavonic гость (gostĭ, “guest”); the root of the noun is disputed.[4]

Earliest recorded meaning

De Vaan dates it from Plautus, who has īnsidiīs hostīlibus, “by an enemy's ambush” (Pseudolus).[4][2] Ennius has a death ordered “by an enemy hand” (hostīlī manū).[2]

Semantic evolution

It means belonging to an enemy (an enemy land, enemy ships) or done by an enemy, and in augury the part of a victim's entrails that concerned the enemy.[2][5] It then describes behaviour typical of an enemy, as in Cicero's hostīlī odiō et crūdēlitāte, “with an enemy's hatred and cruelty”, and an attitude of hostility, as Ovid's eyes burning with hostility.[2]

In medieval Latin an expedītiō hostīlis or iter hostīle was a military expedition (the host), and hostīlia were the dues owed for it.[6] English hostile dates from the late 15th century.[7]
