("Rossum's Universal Robots"), by Karel Capek (1890-1938), from Czech robotnik "slave," from robota "forced labor, compulsory service, drudgery," from robotiti "to work, drudge," from an Old Czech source akin to Old Church Slavonic rabota "servitude," from rabu "slave," from Old Slavic *orbu-, from PIE *orbh- "pass from one status to another" (see orphan). The Slavic word thus is a cousin to German Arbeit "work" (Old High German arabeit). According to Rawson the word was popularized by Karel Capek's play, "but was coined by his brother Josef (the two often collaborated), who used it initially in a short story."

Breton roch).
In Middle English it seems to have been used principally for rock formations as opposed to individual stones. Meaning "precious stone, especially a diamond," is 1908, U.S. slang. Meaning "crystallized cocaine" is attested from 1973, in West Coast U.S. slang. Figurative use for "sure foundation" (especially with reference to Christ) is from 1520s; but also from 1520s as "source of danger or destruction," in reference to shipwrecks (e.g. on the rocks). Also used attributively in names of animals that frequent rocky habitats, e.g. rock lobster (1843). Between a rock and a hard place first attested 1921:

The rock-scissors-paper game is attested by that name from 1976; from 1968 as paper-stone-scissors.

- rocket (n.2)
- type of self-propelling projectile, 1610s, from Italian rocchetto "a rocket," literally "a bobbin," diminutive of rocca "a distaff," so called because of cylindrical shape.

Rocket science in the figurative sense of "difficult, complex process or topic" is attested by 1985. Rocket scientist is from 1952.
That such a feat is considered within the range of possibility is evidenced by the activities of scientists in Europe as well as in America.

The Rocky Mountains so called by 1802, translating French Montagnes Rocheuses, first applied to the Canadian Rockies. "The name is not directly self-descriptive but is an approximate translation of the name of the former Native American people here known as the Assiniboin .... The mountains are in fact not noticeably rocky" [Room]. Bright notes that "These Indians were called /assiniipwaan/, lit. 'stone Sioux', by their Cree (Algonkian) neighbors".
- rococo (adj.)
- 1836, "old-fashioned," from French rococo (19c.), apparently a humorous alteration of rocaille "shellwork, pebble-work" from Middle French roche "rock," from Vulgar Latin *rocca "stone." Specifically of furniture or architecture of the time of Louis Quatorze and Louis Quinze, from 1841. If this is correct, the reference is to the excessive use of shell designs in this lavish style. For differentiation, see baroque. The general sense of "tastelessly florid or ornate" is from 1844.
Much of the painting, engraving, porcelain-work, etc., of the time has ... a real decorative charm, though not of a very high order in art. Hence rococo is used attributively in contempt to note anything feebly pretentious and tasteless in art or literature. [Century Dictionary, 1902]

As a generic name for "a person," attested from 1630s. Slang meaning "penis" was popular c.1650-c.1870; hence the slang verb sense of "to copulate with (a woman)," attested from 1711.
The use of the word in radio communication to mean "yes, I understand" is attested from 1941, from the U.S. military phonetic alphabet word for the letter -R-, in this case an abbreviation for "received." Said to have been used by the R.A.F. since 1938. The Jolly Roger pirate flag is first attested 1723, of unknown origin; jolly here has its otherwise obsolete Middle English sense "high-hearted, gallant."
