tilt (v.1): Old English *tyltan "to be unsteady," from tealt "unsteady," from Proto-Germanic *taltaz (source also of Old Norse tyllast "to trip," Swedish tulta "to waddle," Norwegian tylta "to walk on tip-toe," Middle Dutch touteren "to swing"). Meaning "to cause to lean, tip, slope" (1590s) is from sense of "push or fall over." Intransitive sense "to lean, tip" first recorded 1620s. Related: Tilted; tilting.
timbre (n.): "characteristic quality of a musical sound," 1849, from French timbre "quality of a sound," earlier "sound of a bell," from Old French, "bell without a clapper," originally "small drum," probably via Medieval Greek *timbanon, from Greek tympanon "kettledrum" (see tympanum). Timbre was used in Old French (13c.) and Middle English (14c.) to render Latin tympanum in Ps. 150.
titmouse (n.): small, active bird, early 14c., titmose, from tit (n.2), expressing something small, + Old English mase "titmouse," from Proto-Germanic *maison (source also of Dutch mees, German meise), from adj. *maisa- "little, tiny." Spelling influenced 16c. by unrelated mouse, "when mose had long been obsolete as an independent word" [OED]. The proper plural is titmouses.
anaconda (n.): 1768, a name first used in English to name a Ceylonese python, it was applied erroneously to a large South American boa, called in Brazil sucuriuba. The word is of uncertain origin, and no snake name like it now is found in Sinhalese or Tamil. One suggestion is that it is a Latinization of Sinhalese henacandaya "whip snake," literally "lightning-stem" [Barnhart]. Another suggestion is that it represents Tamil anaikkonda "having killed an elephant" [OED].
anacrusis (n.): "unstressed syllable at the beginning of a verse," 1833, Latinized from Greek anakrousis "a pushing back," of a ship, "backing water," from anakrouein "to push back, stop short, check," from ana- "back" (see ana-) + krouein "to strike," from PIE *kreue- (2) "to push, strike" (source also of Russian krusit, Lithuanian krusu "to smash, shatter," Old Church Slavonic kruchu "piece, bit of food," Old English hreowian "feel pain or sorrow," Old Norse hryggja "make sad").
analemma (n.): 1650s, from Latin analemma "the pedestal of a sundial," hence the sundial itself, from Greek analemma "prop, support," from analambanein "to receive, take up, restore," from ana- "up" (see ana-) + lambanein "to take," from PIE root *(s)lagw- "to seize, take" (source also of Sanskrit labhate, rabhate "seizes;" Old English læccan "to seize, grasp;" Greek lazomai "I take, grasp;" Old Church Slavonic leca "to catch, snare;" Lithuanian lobis "possession, riches").
anchor (n.): Old English ancor, borrowed 9c. from Latin ancora "anchor," from or cognate with Greek ankyra "anchor, hook" (see ankle). A very early borrowing and said to be the only Latin nautical term used in the Germanic languages. The -ch- form emerged late 16c., a pedantic imitation of a corrupt spelling of the Latin word. The figurative sense of "that which gives stability or security" is from late 14c. Meaning "host or presenter of a TV or radio program" is from 1965, short for anchorman.
anchorite (n.): mid-15c., "hermit (especially those of the Eastern deserts), recluse, one who withdraws from the world for religious reasons," from Medieval Latin anchorita, from Greek anakhoretes, literally "one who has retired," agent noun from anakhorein "to retreat, go back, retire," from ana- "back" (see ana-) + khorein "withdraw, give place," from khoros "place, space, free space, room."

Phrase and how as an exclamation of emphatic agreement dates from early 1900s.
Andrew: masc. proper name, from Old French Andreu (Modern French André), from Latin Andreas, from Greek Andreas, from andreios "manly," from aner (genitive andros) "man" (see anthropo-). Andrew Millar (1590s) for some forgotten reason became English naval slang for "government authority," and especially "the Royal Navy." St. Andrew (feast day Nov. 30) has long been regarded as patron saint of Scotland. The Andrew's cross (c. 1400) supposedly resembles the one St. Andrew was crucified on.
android (n.): "automaton resembling a human being," 1837, in early use often in reference to automated chess players, from Modern Latin androides (itself attested as a Latin word in English from 1727), from Greek andro- "male" (see andro-) + -eides "form, shape" (see -oid). Greek androdes meant "like a man, manly;" compare also Greek andrias "image of a man, statue." Listed as "rare" in OED 1st edition (1879), popularized from c. 1951 by science fiction writers.
Angevin: 1650s, "pertaining to the French province of Anjou," from French Angevin, from Medieval Latin Andegavinus, from Andegavum "Angers," city in France, capital of Anjou (Latin Andegavia, from Andecavi, Roman name of the Gaulish people who lived here, which is of unknown origin).

blight (n.): 1610s, origin obscure; according to OED it emerged into literary speech from the talk of gardeners and farmers, perhaps ultimately from Old English blæce, blæcðu, a scrofulous skin condition and/or from Old Norse blikna "become pale." Used in a general way of agricultural diseases, sometimes with suggestion of "invisible baleful influence;" hence figurative sense of "anything which withers hopes or prospects or checks prosperity" (1828). Compare slang blighter. Urban blight attested by 1935.
blindfold (v.): 1520s, alteration, by similarity to fold, of blindfelled (early 14c.), past participle of blindfellan "blindfold, cover the eyes (with a bandage, etc.)," also "to strike blind" (c. 1200), from Old English (ge)blindfellian "to strike blind," from blind (adj.) + Anglian gefeollan "to strike down," as in to fell a tree (see fell (v.)). Related: Blindfolded; blindfolding.
blooper (n.): "blunder," 1943, apparently first in theater, from American English baseball slang meaning "a fly ball in a high arc missed by the fielder" (1937) or else from the earlier sense "radio receiver that interferes with nearby sets" when a careless operator throws it into oscillation (1926), in which case it imitates the resulting sound.

This word is the source of the blown in full-blown.
blue blood (adj.): 1809 in reference to the blood that flows in the veins of the old and aristocratic families of Spain, translating Spanish sangre azul, claimed by certain families of Castile as uncontaminated by Moorish or Jewish admixture; the term is probably from the notion of the visible veins of people of fair complexion. In reference to English families by 1827. As a noun, "member of an old and aristocratic family," by 1877.
bluff (v.): 1839, American English, poker term, perhaps from Dutch bluffen "to brag, boast," or verbluffen "to baffle, mislead." An identical word meant "blindfold, hoodwink" in 1670s, but the sense evolution and connection are unclear; OED calls it "one of the numerous cant terms ... which arose between the Restoration and the reign of Queen Anne." Extended or figurative sense by 1854. Related: Bluffed; bluffing.

The broad flan penny established by Offa remained the principal denomination, with only minor changes, until the fourteenth century.
