1530s, "reversal of what is expected" (especially a fatal turning point in a drama, the winding up of the plot), from Latin catastropha, from Greek katastrophē "an overturning; a sudden end," from katastrephein "to overturn, turn down, trample on; to come to an end," from kata "down" (see cata-) + strephein "turn" (from PIE root *streb(h)- "to wind, turn"). The extension to "sudden disaster" is attested from 1748.
By CATASTROPHISM I mean any form of geological speculation which, in order to account for the phenomena of geology, supposes the operation of forces different in their nature, or immeasurably different in power, from those which we at present see in action in the universe. [Huxley, "Address" to the Geological Society of London, Feb. 19, 1869]
Proto-Indo-European root meaning "to wind, turn."
It forms all or part of: anastrophe; antistrophe; apostrophe (n.1); apostrophe (n.2); boustrophedon; catastrophe; epistrophe; strabismus; strap; strep; strepto-; streptococcus; streptomycin; strobe; strobic; stroboscope; strop; strophe; strophic.
It is the hypothetical source of/evidence for its existence is provided by: Greek strophe "stanza," originally "a turning," strephein "to turn," strophaligs "whirl, whirlwind," streblos "twisted," stremma "that which is twisted."
mid-13c., "sacrifice by fire, burnt offering," from Old French holocauste (12c.), or directly from Late Latin holocaustum, from Greek holokauston "a thing wholly burnt," neuter of holokaustos "burned whole," from holos "whole" (from PIE root *sol- "whole, well-kept") + kaustos, verbal adjective of kaiein "to burn" (see caustic).
Originally a Bible word for "burnt offerings," given wider figurative sense of "massacre, destruction of a large number of persons" from 1670s. The Holocaust "Nazi genocide of European Jews in World War II," first recorded 1957, earlier known in Hebrew as Shoah "catastrophe." The word itself was used in English in reference to Hitler's Jewish policies from 1942, but not as a proper name for them.
English chronicler Richard of Devizes in his contemporary account of the coronation of Richard I in 1189 used the word holocaust when he described the mass murder of the Jews of London, although he meant it as "a sacrificial offering."
1590s, "close study or thought;" 1610s, "a product of such study or thought, literary work showing signs of too-careful elaboration," from Latin lucubrationem (nominative lucubratio) "nocturnal study, night work," noun of action from past-participle stem of lucubrare, literally "to work by artificial light," from stem of lucere "to shine," from suffixed (iterative) form of PIE root *leuk- "light, brightness."

The current story in antiquity was that Aeschylus had been killed near Gela in Sicily by a tortoise dropt on his head by an eagle, which mistook the bald shiny pate of the venerable poet for a stone, and hoped to smash the tortoise on it. See Biographi Graeci, ed. Westermann, p. 120 ; Aelian Nat. Anim. vii. 16 ; Suidas, s.v. Αίσχύλοσ ; Valerius Maximus, ix. 12. Ext. 2. This important topic has produced the usual crop of learned dissertations. The late Professor F. G. Welcker gravely discussed it by the help of ornithological information derived from Aesop's fables, notes of travel made by the professor himself on the supposed scene of the catastrophe, and statistics as to the number of bald-headed men in antiquity. The interesting inquiry has since been prosecuted by other scholars with equal judgment and learning. The reader who desires to peruse these ponderous lucubrations should consult Rheinisches Museum, N.F. 7 (1850), pp. 139-144, 285 sq ; id., 9 (1854), pp. 148-155, 160* ; id., 37 (1882), pp. 308-312 ; Fleckeisen's Jahrbücher, 26 (1880), pp. 22-24 ; Welcker, Antike Denkmäler, 2. pp. 337-346. [J.G. Frazer, notes to Pausanias's "Description of Greece," 1898]
late 12c., "olive oil," from Anglo-French and Old North French olie, from Old French oile, uile "oil" (12c., Modern French huile), from Latin oleum "oil, olive oil" (source of Spanish, Italian olio), from Greek elaion "olive tree," from elaia (see olive).
Nearly all the European languages' words for "oil" (Croatian ulje, Polish olej, Hungarian olaj, Albanian uli, Lithuanian alejus, etc.) are from the Greek word; the Germanic (except Gothic) and Celtic one coming from Greek via Latin: Old English æle, Dutch olie, German Öl, Welsh olew, Gaelic uill, etc.
In English it meant "olive oil" exclusively till c. 1300, when the word began to be extended to any fatty, greasy liquid substance (usually flammable and insoluble in water). Often especially "oil as burned in a lamp to afford light" (as in midnight oil, symbolizing late work). Use for "petroleum" is recorded from 1520s but not common until 19c.
The artist's oils (1660s), short for oil-color (1530s), are paints made by grinding pigment in oil; oil-painting "art or craft of painting in oils" is by 1690s. The ocean-going oil-tanker is from 1900; oil-spill in the environmental catastrophe sense is by 1924. As a condiment, oil and vinegar is attested from 1620s. The figurative expression pour oil upon the waters "appease strife or disturbance" is by 1840, from an ancient trick of sailors.
Another historical illustration which involves monolayers, was when sailors poured oil on the sea in order to calm 'troubled waters' and so protect their ship. This worked by wave damping or, more precisely, by preventing small ripples from forming in the first place so that the wind could have no effect on them. [J. Lyklema, "Fundamentals of Interface and Colloid Science," Academic Press, 2000]
The phenomenon depends on what are called Marangoni effects; Benjamin Franklin experimented with it in 1765.
