accelerate c.1525, from L. acceleratus, pp. of accelerare "quicken," from ad- "to" + celerare "hasten," from celer "swift" (see celerity). Accelerator in motor vehicle sense is first recorded 1900. celerity 1483, from M.Fr. c�l�rit�, from L. celeritatem (nom. celeritas), from celer "swift," from PIE base *kel- "to drive, set in swift motion" (cf. Skt. carati "goes," Gk. keles "fast horse or ship," keleuthos "journey, road," Lith. sulys "a gallop," O.H.G. scelo "stallion").
