Origin: Formed within English, by derivation. Etymons: accelerate v., -ed suffix¹.

Etymology: < accelerate v. + -ed suffix¹. Compare French accéléré (1611), Spanish acelerado (first half of the 15th cent.), Italian accelerato (1354). Compare earlier accelerate adj.

1. Made faster or more rapid; increased in speed. In Physics: subjected to acceleration; supplied with kinetic energy.
