spud
c.1440 "small or poor knife," of uncertain origin probably related to Dan. spyd, O.N. spjot "spear," Ger. Spiess "spear, lance"). Meaning "spade" is from 1667; sense of "short or stumpy person or thing" is from 1687; that of "potato" is first recorded 1845 in New Zealand English.
rocket
"projectile," 1611, from It. rocchetto "a rocket," lit. "a bobbin," dim. of rocca "a distaff," so called because of cylindrical shape. The It. word probably is from a Gmc. source (cf. O.H.G. rocko "distaff," O.N. rokkr), from P.Gmc. *rukka-, from PIE base *rug- "to spin." Originally "fireworks rocket," meaning "device propelled by a rocket engine" first recorded 1919; rocket-ship first attested 1927. The verb meaning "to spring like a rocket" is from 1883.
