Definition fast

Etymology 1

From Middle English fast, from Old English f�st (�fast, fixed, firm, secure; constant, steadfast; stiff, heavy, dense; obstinate, bound, costive; enclosed, closed, watertight; strong, fortified�), from Proto-Germanic *fastaz, *fastijaz, *fastuz (�fast, firm, secure�); see it for cognates and further etymology.

The development of �rapid� from an original sense of �secure� apparently happened first in the adverb and then transferred to the adjective; compare hard in expressions like �to run hard�. The original sense of �secure, firm� is now slightly archaic, but retained in the related fasten (�make secure�).
