hostis

• ostis (Late Latin, Medieval Latin)
• fostis (rare)
• ost (Medieval Latin, rare)

From Proto-Italic *hostis, from Proto-Indo-European *gʰóstis (“guest, stranger”), whence also Proto-Germanic *gastiz (English guest) and Proto-Slavic *gostь. Varro (de lingua latina 5.4) confirms this: tum eō verbō dīcēbant peregrīnum [...], nunc dīcunt eum quem tum dīcēbant perduellem. ("Back then this word meant a stranger, today it means the same as perduellis - an enemy of the state.").

• (modern Italianate Ecclesiastical) IPA^(key): /ˈos.tis/, [ˈɔst̪is]
