disaster: [16] The word disaster has astrological connotations. It comes, perhaps via French désastre, from Italian disastro; this was a backformation from disastrato, literally ‘ill-starred’, a compound adjective formed from the pejorative prefix dis- and astro ‘star’, a descendant of Latin astrum ‘star’. This in turn came from Greek astron ‘star’, source of English astronomy and related to English star. So the underlying meaning of the word is ‘malevolent astral influence’. Provençal has the parallel malastre ‘misfortune’.
