First attested in the 1520s. Either from Latin accelerātus, perfect passive participle of accelerō (“to accelerate, hasten”) (see -ate (verb-forming suffix) and -ate (adjective-forming suffix)), formed from ad + celerō (“to hasten”), which is from celer (“quick”) (see celerity), or back-formation from acceleration.
