The story

Borrowed from French calamiteux (‘calamitous’) (see French -eux, English -ous), from Latin calamitōsus (‘destructive, disastrous, ruinous, calamitous’), a contraction of calamitātōsus, from calamitāt- + -ōsus (suffix meaning ‘full of; prone to’ forming adjectives from nouns); calamitāt- is the oblique stem of calamitās (‘disaster, misfortune, calamity; damage, harm; loss’), from *calamis (‘damaged’) (ultimately from Proto-Indo-European *kelh₂- (‘to beat; to break’)) + -tās (suffix forming abstract nouns denoting a condition or state).
