stock (n.1)

Old English stocc "stump, post, stake, tree trunk, log," also "pillory" (usually plural, stocks), from Proto-Germanic *stauk- "tree trunk" (source also of Old Norse stokkr "block of wood, trunk of a tree," Old Saxon, Old Frisian stok, Middle Dutch stoc "tree trunk, stump," Dutch stok "stick, cane," Old High German stoc "tree trunk, stick," German Stock "stick, cane;" also Dutch stuk, German Stück "piece"), from an extended form of PIE root *(s)teu- (1) "to push, stick, knock, beat" (see steep (adj.)).

Meaning "ancestry, family" (late 14c.) is a figurative use of the "tree trunk" sense (as in family tree). This is also the root of the meaning "heavy part of a tool," and "part of a rifle held against the shoulder" (1540s). Meaning "person as dull and senseless as a block or log" is from c. 1300; hence "a dull recipient of action or notice" (1540s).

Meaning "framework on which a boat was constructed" (early 15c.) led to figurative phrase on stocks "planned and commenced" (1660s). Taking stock "making an inventory" is attested from 1736. Stock, lock, and barrel "the whole of a thing" is recorded from 1817. Stock-still (late 15c.) is literally "as still as a tree trunk."

plate (n.)

mid-13c., "flat sheet of gold or silver," also "flat, round coin," from Old French plate "thin piece of metal" (late 12c.), from Medieval Latin plata "plate, piece of metal," perhaps via Vulgar Latin *plattus, formed on model of Greek platys "flat, broad" (from PIE root *plat- "to spread"). The cognate in Spanish (plata) and Portuguese (prata) has become the usual word for "silver," superseding argento via a shortening of *plata d'argento "plate of silver, coin."

From 14c. as "armor made of sheets of metal." Meaning "table utensils" (originally of silver or gold only) is from Middle English. Meaning "shallow dish on which food is served at table," now usually of china or earthenware, originally of metal or wood, is from mid-15c. Meaning "articles which have been covered with a plating of precious metal" is from 1540s.

In photography, "common rectangular piece of glass used to receive the picture," by 1840. The baseball sense "home base" is from 1857. Geological sense "nearly rigid part of the earth's lithosphere" is attested from 1904; plate tectonics is attested from 1967. Plate-glass for a superior kind of thick glass used for mirrors, shop-windows, etc., is recorded from 1729.

noctilucent (adj.)

"shining by night," as the eyes of a cat, glow-worms, decaying wood, or certain high clouds seen in northern latitudes, 1812, from Latin noct-, stem of nox "night" (see noct-) + lucentem (nominative lucens), present participle of lucere "to shine, glow, be bright," from PIE root *leuk- "light, brightness." The word was originally used of tiny sea creatures, by contemporary observers reported to be nereids, but that identification is now considered doubtful.

These are the animals that illuminate the sea, like glow-worms, but with brighter splendor. I have at night, in rowing, seen the whole element as if on fire round me; every oar spangled with them; and the water burnt with more than ordinary brightness. I have taken up some of the water in a bucket, seen them for a short space illuminate it; but when I came to search for them their extreme smallness eluded my examination. [Thomas Pennant, "British Zoology," London, 1812]

Also noctilucous (1774). Noctilucid is rarely used, but could be valuable if it meant "only making sense at night." Related: Noctilucence.

bucket (n.)

"pail or open vessel for drawing and carrying water and other liquids," mid-13c., from Anglo-French buquet "bucket, pail," from Old French buquet "bucket," which is from Frankish or some other Germanic source, or a diminutive of cognate Old English buc "pitcher, bulging vessel," originally "belly" (buckets were formerly of leather as well as wood), both from West Germanic *buh- (source also of Dutch buik, Old High German buh, German Bauch "belly"), possibly from a variant of PIE root *beu-, *bheu- "to grow, swell" (see bull (n.2)).

To kick the bucket "die" (1785) perhaps is from an unrelated bucket "beam on which something may be hung or carried" (1570s), from French buquet "balance," a beam from which slaughtered animals were hung (by the heels or hooves). This was perhaps reinforced by the notion of suicide by hanging after standing on an upturned bucket; but Farmer calls attention to bucket "a Norfolk term for a pulley." Bucket list "list of experiences or achievements one hopes to have or accomplish during one's remaining life," is by 2007, probably based on kicking the bucket as "dying," but the phrase was used earlier in algorithm sorting.

rod (n.)

Middle English rod, rodde, "a stick of wood," especially a straight cutting from a woody plant, stripped of twigs, and having a particular purpose" (walking stick, wand of office, instrument of punishment), from Old English rodd "a rod, pole," which is probably cognate with Old Norse rudda "club," from Proto-Germanic *rudd- "stick, club," from PIE *reudh- "to clear land." Other sources formerly consider it to correspond to the continental words under rood.

As a long, tapering elastic pole for fishing, from mid-15c. Figurative sense of "offshoot" (mid-15c.) led to Biblical meaning "scion, tribe." As an instrument of punishment, attested from mid-12c.; also used figuratively for "any sort of correction or punishment" (14c.). In mechanics, "any bar slender in proportion to its length" (1728).

As a unit of linear measure (5½ yards or 16½ feet, also called perch or pole) attested from late 14c., from the pole used to mark it off. As a measure of land area, "a square perch," from late 14c., the usual measure in brickwork. Meaning "light-sensitive cell in a retina" is by 1837, so-called for their shape. Slang meaning "penis" is recorded from 1902; that of "handgun, pistol, revolver" is by 1903.

rune (n.)

a modern book-form to represent Old English run, rune "secret, mystery, dark mysterious statement, (secret) council," also "a runic letter" (runstæf), from Proto-Germanic *runo (source also of Old Norse run "a secret, magic sign, runic character," Old High German runa "a secret conversation, whisper," Gothic runa), from PIE *ru-no-, source of technical terms of magic in Germanic and Celtic (source also of Gaelic run "a secret, mystery, craft, deceit, purpose, intention, desire," Welsh rhin "a secret, charm, virtue"). Also see Runnymede.

The word entered Middle English as roun and by normal evolution would have become Modern English *rown, but it died out mid-15c. when the use of runes did. The modern usage is from late 17c., from German philologists who had reintroduced the word in their writings from a Scandinavian source (such as Danish rune, from Old Norse run).

The presumption often is that the magical sense was the original one in the word and the use of runes as letters was secondary to ancient Germanic peoples, but this is questioned by some linguists. The runic alphabet itself is believed to have developed by 2c. C.E. from contact with Greek writing, with the letters modified to be more easily cut into wood or stone. Related: Runed; runecraft.

phalanx (n.)

1550s, "line of battle in close ranks," from Latin phalanx "compact body of heavily armed men in battle array," or directly from Greek phalanx (genitive phalangos) "line of battle, battle array," also "finger or toe bone," originally "round piece of wood, trunk, log," a word of unknown origin. Perhaps from PIE root *bhelg- "plank, beam" (source of Old English balca "balk;" see balk (n.)).

In anatomy, originally the whole row of finger joints, which fit together like infantry in close order. Figurative sense of "number of persons banded together in a common cause" is attested from 1600 (compare Spanish Falangist, member of a fascist organization founded in 1933).

The celebrated Macedonian phalanx was normally drawn up sixteen ranks deep, the men being clad in armor, bearing shields, and armed with swords and with spears from 21 to 24 feet long. In array the shields formed a continuous bulwark, and the ranks were placed at such intervals that five spears which were borne pointed forward and upward protected every man in the front rank. The phalanx on smooth ground, and with its flanks and rear adequately protected, was practically invincible; but it was cumbrous and slow in movement, and if once broken could only with great difficulty be reformed.

separate (adj.)

"detached, kept apart, divided from the rest," c. 1600, from separate (v.) or from Latin separatus. Separate also was used as a past-participle adjective in Middle English, "cut off from the main body," also, of a spouse, "estranged." The meaning "individual, particular" is from 1670s, on the notion of "withdrawn or divided from something else," hence "peculiar to one but not others."

Separate but equal in reference to U.S. segregation policies on railroads, etc. is attested by 1890 (Henry W. Grady); it was used in 1870s of medical courses for women at universities. Separate development, official name of apartheid in South Africa, is from 1955. Related: Separately (1550s); separateness.

Frequently the colored coach is little better than a cattle car. Generally one half the smoking car is reserved for the colored car. Often only a cloth curtain or partition run half way up separates this so-called colored car from the smoke, obscene language, and foul air of the smokers' half of the car. All classes and conditions of colored humanity, from the most cultured and refined to the most degraded and filthy, without regard to sex, good breeding or ability to pay for better accommodation, are crowded into this separate, but equal (?) half car. [Rev. Norman B. Wood, "The White Side of a Black Subject," 1897]

axe (n.)

"edged instrument for hewing timber and chopping wood," also a battle weapon, Old English ces (Northumbrian acas) "axe, pickaxe, hatchet," later x, from Proto-Germanic *akusjo (source also of Old Saxon accus, Old Norse ex, Old Frisian axe, German Axt, Gothic aqizi), from PIE *agw(e)si- "axe" (source also of Greek axine, Latin ascia).

The spelling ax is better on every ground, of etymology, phonology, and analogy, than axe, which became prevalent during the 19th century; but it is now disused in Britain. [OED]
The spelling ax, though "better on every ground, of etymology, phonology, & analogy" (OED), is so strange to 20th-c. eyes that it suggests pedantry & is unlikely to be restored. [Fowler] 

Meaning "musical instrument" is 1955, originally jazz slang for the saxophone; rock slang for "guitar" dates to 1967. To have an axe to grind is from a Sept. 7, 1810, essay in the Luzerne (Pennsylvania) "Gleaner" by U.S. editor and politician Charles Miner (1780-1865) in which a man flatters a boy and gets him to do the chore of axe-grinding for him, then leaves without offering thanks or recompense. It was published in a collection in 1815 titled "Essays From the Desk of Poor Robert the Scribe." The story ("Who'll Turn the Grindstone?") has been misattributed since late 19c. to Benjamin Franklin, a mistake continued in Weekley, OED print edition, "Century Dictionary," and many other sources (Bartlett's "Familiar Quotations" has gotten it right since 1870).
