calamitous

Etymology

It is borrowed from Middle French calamiteux,^{[2][3][4][5][6]} from Latin calamitōsus (“causing loss, destructive; liable to damage”),^[5][2][4] a contraction of *calamitātōsus,^[2][6] from calamitās (“damage, loss, disaster, adversity”), the source of calamity.^[5][2][4] The Shorter Oxford allows either French or Latin as the immediate source,^[7] and Dictionary.com takes it as calamity with -ous.^[8] According to the OED, the contracted ending gave a model for similar words in French and English in -itous.^[4] The origin of the Latin noun is obscure.^[5] Roman writers linked it with calamus (“straw, corn-stalk”), thinking of damage to crops, but the OED finds the suffix hard to fit and Etymonline calls this folk etymology.^[4][5] It may be related instead to incolumis (“uninjured”) and come from Proto-Indo-European *kel- (“to strike, cut”).^[5][2][6]

Earliest recorded meaning

Bringing or full of disaster and misery: 1545, in G. Joye's Exposicion of Daniel.^[4][2][3]

Semantic evolution

The word has kept its first meaning, of events and circumstances, with little change.^[4][3] For about a century it could also describe people struck by misfortune: the OED records this from 1668 to 1752,^[4] and Johnson (1755) gave it first, "miserable; involved in distress", before the sense of external things, which he illustrated from Milton's "calamitous constraint".^[9] Merriam-Webster quotes Johnson himself for this use, now obsolete: "thou hast seen me happy and calamitous".^[3] The noun calamitousness dates from the mid 17th century, and the adverb calamitously from the late 18th.^[7]
