1801, "a 'volley of words,' " from Fr. tirade "speech, volley, shot, continuation, drawing out" (16c.), from tirer "draw out, endure, suffer," or the Fr. word is perhaps from cognate It. tirata "a volley," from pp. of tirare "to draw." The whole Romanic word group is of uncertain origin; some think
it is a shortening of the source of O.Fr. martirer "endure martyrdom" (see martyr).
