presto (adv.)

1590s, "quickly, immediately," a word used by conjurers, etc., from Italian presto "quick, quickly" in conjuror's patter, from Latin praestus "ready," praesto (adv.) "ready, available," from prae "before" (see pre-) + stare "to stand," from PIE root *sta- "to stand, make or be firm." Compare Latin praesto esse "to be at hand, be ready," source of French prêt "ready," and compare press (v.2). As a musical direction, "in rapid tempo," it is a separate borrowing from Italian, first recorded 1680s (Purcell).
