The English adjective frugivorous “fruit-eating” is used mostly in biology to describe animals that eat fruit. The first element, frugi-, is a combining form of Latin frux “fruit, crops, produce” related to the verb fruī “to enjoy the fruits or products or results of.” From the form frūg- English has frugal and frugivorous. From fructus, the past participle of fruī (from an assumed frūguī), English has fruit (from Old French, from Latin frūctus) and fructify (from Old French fructifier, from Latin frūctificāre). The second element, -vorous, ultimately comes from Latin vorāre “to swallow ravenously,” whence English has devour (from Middle French devourer, from Latin dēvorāre “to swallow down,” and voracious (from Latin vorāc-, the stem of vorax “ravenous, insatiable.” Frugivorous entered English in the 18th century.

English velitation comes from Latin vēlitātiōn- (stem of vēlitātiō) “skirmish,” ultimately a derivation of vēles (stem vēlit-) “light-armed foot soldier wearing little armor, skirmisher,” which is a derivative from the adjective vēlox (stem vēlōc-) “quick, rapid, speedy” (and the source of English velocity). The vēlitēs, a specialized unit of soldiers in the ancient Roman army, were armed with swords, javelins, and small round shields and were stationed in front of the legionary lines. Before the main action began, these skirmishers threw their javelins at the enemy lines to break up their formation and then rapidly withdrew to the rear of the legionary lines. Vēlitēs as a type of soldier or unit in the Roman army were relatively brief: they are first mentioned about 211 b.c. in the dark, dark days (for Rome) of the Second Punic War (218–201 b.c.). The vēlitēs were probably formed owing to lowered property qualifications for military service in 214 b.c. and were drawn from the lowest, youngest, and poorest citizens. Vēlitēs are last mentioned in the Jugurthine War of 112-106 b.c.; presumably they were subsumed into the centuries (a company consisting of approximately 100 men) in a later reorganization of the Roman army. Velitation entered English in the 17th century.
