Pronunciation

  • Classical: [akˈkɛ.ɫɛ.roː][1]
  • Ecclesiastical: [atˈt͡ʃɛː.le.ro][1]

Forms

accelerō (present infinitive accelerāre, perfect active accelerāvī, supine accelerātum); first conjugation[1] Also spelt adcelerō.[2][3]

Etymology

It is from Latin ad- + celerō (“to hasten”),[2][4] from celer (“swift”),[5][6] which de Vaan traces to Proto-Indo-European *kel-i- (“speeding”).[5]

Earliest recorded meaning

It is first found in Accius,[5] in a tragedy, of quickening one's pace (gressum adcelerasse).[2][3]

Semantic evolution

Transitively it meant quickening one's step, making something travel faster and speeding up an action, as reading in Quintilian;[2][3] it was also used for hastening an event, such as death in Lucretius, a march in Caesar or someone's consulship in Tacitus.[2][3] Intransitively it meant to hurry, in Cicero and Silius Italicus,[2][4] and Ecclesiastical Latin kept the sense “make haste”.[7] English accelerate was formed from its past participle.[6]
