late 14c., "act of plundering" (especially in war), from Old French pilage (14c.) "plunder," from pillier "to plunder, loot, ill-treat," possibly from Vulgar Latin *piliare "to plunder," probably from a figurative use of Latin pilare "to strip of hair," perhaps also meaning "to skin" (compare figurative extension of verbs pluck, fleece), from pilus "a hair" (see pile (n.3)).
Pillage and spoil especially suggest the great loss to the owner, completely stripping or despoiling them of their property ; plunder suggests the quantity and value of that which is taken : as, loaded with plunder; booty is primarily the spoils of war, but also of a raid or combined action, as of pirates, brigands, or burglars ....

"to plunder, despoil, strip of money or goods by open violence," 1590s, from pillage (n.). Related: Pillaged; pillaging; pillager. The earlier form of the verb in English was simply pill (late Old English pilian), which probably is from Medieval Latin pillare.
"plunderer," mid-14c., pilour, from obsolete verb pill "to plunder, to pillage" (see pillage (v.)). Related: Pillery "robbery, plunder" (mid-15c.).
"larva of a butterfly or moth," mid-15c., catyrpel, probably altered (by association with Middle English piller "plunderer;" see pillage (n.)) from Old North French caterpilose "caterpillar" (Old French chatepelose), literally "shaggy cat" (probably in reference to the "wooly-bear" variety), from Late Latin catta pilosa, from catta "cat" (see cat (n.)) + pilosus "hairy, shaggy, covered with hair," from pilus "hair" (see pile (n.3)).
Compare also French chenille "caterpillar," literally "little dog." A Swiss German name for it is teufelskatz "devil's cat." "The caterpillar has in many idioms received the name of other animals" [Kitchin, who cites also Milanese cagnon "little dog," Italian dialectal gattola "little cat," Kentish hop-dog, hop-cat, Portuguese lagarta "lizard."] Compare also American English wooly-bear for the hairy variety. An Old English name for it was cawelworm "cole-worm." Caterpillar tractor, one which travels on endless steel belts, is from 1908, so called from its way of moving.

Its sense of "to kill and devour" (an animal) is attested in English from mid-14c. Related: Preyed; preyer; preying.
