festinus
From Proto-Italic *fristis (“haste”) + -nus, with *fristis only finding secure cognates in Celtic such as Welsh brys.[1]
festīnus (feminine festīna, neuter festīnum); first/second-declension adjective
According to Döderlein, celer and citus mean "swift, fast, quick" in terms of quick motion (in general) with tardus as their antonym. More specifically, citus refers to a lively motion, whereas celer refers to an eager or impetuous motion.
On the other hand, pernīx and vēlōx as "quick" denote a level of athletic nimbleness in terms of bodily activity, with lentus as their antonym. More specifically, pernīx involves a level of dexterity and quickness in an eclectic range of actions (such as climbing, hurdling, jumping, vaulting, etc.); whereas vēlōx is especially used for running, swimming and flying (moving in a direction)
Thirdly, festīnus and properus as "quick" refer specifically to one's speed in terms of the shortest time to reach a destination, with sēgnis as their antonym. More specifically, festīnus intimates a certain level of impatience, whereas properus simply indicates a haste from energy simply.
First/second-declension adjective.
