"rectangular groove or channel cut out of the edge of a board or piece of stone so that it will join by overlapping with the next piece, similarly cut," late 14c., rabet, from Old French rabat "a recess in a wall, a lower section," literally "a beating down or back," a back-formation from rabattre "to beat down, beat back" (see rebate (v.); the noun is a doublet of this word).
The verb, meaning "to groove or fit (boards, etc.) by cutting rabbets" is attested from mid-15c. (implied in rabatted, rabetynge); Middle English also had rabet "joiner's plane, rabbet-plane" (mid-15c., from Old French rabot).
"Jewish doctor of religious law," early 14c. (in late Old English in biblical context only, as a form of address); in Middle English as a title prefixed to personal names, also "a spiritual master" generally; from Late Latin rabbi, from Greek rhabbi, from Mishnaic Hebrew rabbi "my master."
This is formed from -i, first person singular pronominal suffix, + rabh "master, great one," title of respect for Jewish doctors of law. This is from the Semitic root r-b-b "to be great or numerous" (compare robh "multitude;" Aramaic rabh "great; chief, master, teacher;" Arabic rabba "was great," rabb "master").
"pertaining to rabbis or their language, learning, or opinions," 1620s, earlier rabbinic (1610s); see rabbi + -ical. The -n- is perhaps via rabbin "rabbi" (1520s), an alternative form, from French rabbin or directly from Medieval Latin rabbinus (also source of Italian rabbino, Spanish and Portuguese rabino), perhaps from a presumed Semitic plural in -n, or from Aramaic rabban "our teacher," "distinguishing title given to patriarchs and the presidents of the Sanhedrin since the time of Gamaliel the Elder" [Klein], from Aramaic plural of noun use of rabh "great."
common burrowing mammal, identified as a rodent, noted for prolific breeding, late 14c., rabet, "young of the coney," suspected to be from Walloon robète or a similar northern French dialect word, a diminutive of Flemish or Middle Dutch robbe "rabbit," which are of unknown origin. "A Germanic noun with a French suffix" [Liberman]. The adult was a coney (q.v.) until 18c.
Zoologically speaking, there are no native rabbits in the United States; they are all hares. But the early colonists, for some unknown reason, dropped the word hare out of their vocabulary, and it is rarely heard in American speech to this day. When it appears it is almost always applied to the so-called Belgian hare, which, curiously enough, is not a hare at all, but a true rabbit. [Mencken, "The American Language"]
Rabbit punch "chop on the back of the neck" (1915) is so called from resemblance to a gamekeeper's method of dispatching an injured rabbit. Pulling rabbits from a hat as a conjurer's trick recorded by 1843. Rabbit's foot "good luck charm" is attested by 1879 in U.S. Southern black culture. Earlier references are to its use as a tool to apply cosmetic powders.
[N]ear one of them was the dressing-room of the principal danseuse of the establishment, who was at the time of the rising of the curtain consulting a mirror in regard to the effect produced by the application of a rouge-laden rabbit's foot to her cheeks, and whose toilet we must remark, passim, was not entirely completed. [New York Musical Review and Gazette, Nov. 29, 1856]
Rabbit-hole is by 1705. Rabbit ears "dipole television antenna" is from 1950. Grose's 1785 "Dictionary of the Vulgar Tongue" has "RABBIT CATCHER. A midwife."
c. 1300, "pack of animals" (a sense now obsolete), of uncertain origin, but possibly related to Middle English rablen "to gabble, speak in a rapid, confused manner" (mid-14c.), which is probably imitative of hurry, noise, and confusion (compare Middle Dutch rabbelen, Low German rabbeln "to chatter").
The meaning "tumultuous crowd of vulgar, noisy people" is from late 14c., probably a back-formation from the Middle English verb. It was applied contemptuously to the common or low part of any populace, regardless of tumult, by 1550s.
"iron bar, bent at right angles at one end, for stirring molten metal," 1864, from French râble, from Old French roable, from Latin rutabulum "rake, fire shovel" (in Medieval Latin also rotabulum), from ruere "to churn or plow up, dig out," (from PIE *reuo-, source also of Sanskrit ravisam, ravat "to wound, hurt;" Lithuanian ráuti "to tear out, pull," ravėti "to weed;" Russian ryt'i, roju "to dig," Old Church Slavonic rylo "spade," Old Norse ryja "to tear out wool," German roden "to root out").
