hostīlis

1. Adversarius is the generic term for every opposer, in the field, in politics, in a court of judicature, like ἀντιστάτης. Hostis (from ἔχθω) is ‘the enemy’ in the field, and war, opp. to pacatus. Cic. Rep. ii. 3. Sen. Q. N. vi. 7. like πολέμιος; inimicus, ‘an enemy’ in heart, opp. to amicus, like ἐχθρός. Cic. Man. 10. Pompeius sæpius cum hoste conflixit, quam quisquam cum inimico concertavit. Phil. xi. 1. Verr. i. 15. Curt. vii. 10. Liv. xxii. 39. Nescio an infestior hic adversarius, quam ille hostis maneat. 2. Hostilis and inimicus denote states of hatred become habitual qualities; infestus and infensus only as temporary states; infestus (ἀνασπαστός?) applies to a quiescent state of aversion, like disaffected, unkind, and thus it is applied to inanimate things that threaten hostility; infensus (from πένθος) denotes a passionate state of mind, like enraged, and is therefore applicable to persons only. Tac. Ann. xv. 28. Non infensum, nedum hostili odio Corbulonis nomen habebatur. Cic. Verr. iii. 24. Sall. Cat. 19. Sen. N. Q. iii. pr. Animus luxuriæ non adversus tantum, sed et infestus. Liv. ii. 20. Tarquinium infesto spiculo petit; Tarquinius infenso cessit hosti. (iv. 393.)
