Pronunciation

  • Classical: [ka.ɫa.mɪˈtoː.sʊs][1]
  • Ecclesiastical: [ka.la.miˈtɔː.s̬us][1]

Forms

calamitōsus (feminine calamitōsa, neuter calamitōsum, comparative calamitōsior, superlative calamitōsissimus); first/second-declension adjective[1]

Etymology

It is from Latin calamitās (“loss, disaster”) + -ōsus.[2][1][3] De Vaan lists it among the derivatives of ⟨calamitās⟩, which he takes from an adjective Proto-Italic *kalamo- (“damaged”), perhaps Proto-Indo-European *kl̥h₂-em-o- (“beaten, damaged”); the same adjective, negated, is in incolumis (“unharmed, safe”).[4]

Earliest recorded meaning

De Vaan dates it from Cato,[4][5] who uses it of land and of people exposed to damage: a farm should have a good climate “so that it is not liable to disaster”, and the trader, though energetic, is said to lead a risky life “liable to ruin”.[2]

Semantic evolution

In Cicero it is mostly “stricken by disaster, wretched”, as in “miserable and ruined men”, and as a noun “the unfortunate”, whom an advocate defends.[2] The active sense “ruinous, calamitous” is also Ciceronian: he says Verres swept through every part of the province like a destructive storm and plague.[2][6] With a more passive sense Cicero says that it is a calamity to be stripped of one's goods, and a worse one with disgrace.[2]

Church Latin glosses it “calamitous”,[7] and Köbler records it in a medieval Life of Bruno of Cologne (967–969).[5] English took calamitous from French calamiteux, from this word, in the 1540s.[8]
