Why is the ninth month called September?
c.1600, "act of carrying off," from Middle French rapture, from Medieval Latin raptura "seizure, rape, kidnapping," from Latin raptus "a carrying off, abduction, snatching away; rape" (see rapt). Earliest attested use in English is of women and in 17c. it sometimes meant rape (v.), which word is a cognate of this. Sense of "spiritual ecstasy, state of mental transport" first recorded c.1600 (raptures).
1630s, from rapture (n.). Related: Raptured; rapturing.
