Forms
exitiōsus (feminine exitiōsa, neuter exitiōsum); first/second-declension adjective[1] It is also spelled exsitiōsus.[2]
Etymology
It is from Latin exitium (“destruction”) + -ōsus.[3][1] exitium comes from exeō (“to go out”), a compound of eō (“to go”),[4] which de Vaan traces to Proto-Italic *ei- (“to go”) and Proto-Indo-European *h₁ei- (“to go”).[5] Isidore explained the word as “that which is destruction to many”.[2]
Earliest recorded meaning
Köbler and Lewis & Short find it first in Cicero, who uses it of the Catilinarian conspiracy.[4][6]
Semantic evolution
It means causing death or destruction, pernicious, deadly.[3][1] Lewis & Short call it rare but classical: Cicero speaks of a ruinous conspiracy and of a slaughter that would have been fatal to the state.[6] An ancient list of synonyms groups it with perīculōsus, pestifer and perniciōsus.[2]
