Word History

Etymology

Noun (1)

borrowed from Middle French roquete, borrowed from Italian (15th-century) ruchetta, rochetta, from ruca "arugula" (going back to Latin ērūca "arugula, caterpillar," of uncertain origin) + -etta, diminutive suffix, going back to Latin -itta

Note: The sense "caterpillar" of Latin ērūca has been taken as the original one, with the plant so called from the resemblance of its hairy stems to a caterpillar. If this is the case, ērūca could be a derivative of *ēr "hedgehog" (see urchin); the suffix may be the same as in festūca "stalk, straw," lactūca "lettuce," and verrūca "wart."

Noun (2)

Italian rocchetta, literally, small distaff, from diminutive of rocca distaff, of Germanic origin; akin to Old High German rocko distaff
