deva (n.)

"god, divinity, good spirit" in Hindu religion, 1819, from Sanskrit deva "a god" (as opposed to asuras "wicked spirits"), etymologically "a shining one," from *div- "to shine," thus cognate with Greek dios "divine" and Zeus, and Latin deus "god" (Old Latin deivos), from PIE root *dyeu- "to shine," in derivatives "sky, heaven, god."

Fem. form devi is used for "goddess," also (with capital D-) for the mother goddess in Hinduism. Hence, also, devadasi "temple dancing girl," literally "female servant of a god," from dasi "slave girl." Also Devanagari, the formal alphabet of Sanskrit writings (1781), which is literally "divine city (script)," from nagara "city," but which is perhaps short for nagari lipi "town writing."

divination (n.)

late 14c., divinacioun, "act of foretelling by supernatural or magical means the future, or discovering what is hidden or obscure," from Old French divination (13c.), from Latin divinationem (nominative divinatio) "the power of foreseeing, prediction," noun of action from past-participle stem of divinare, literally "to be inspired by a god," from divinus "of a god," from divus "a god," related to deus "god, deity" (from PIE root *dyeu- "to shine," in derivatives "sky, heaven, god"). Related: Divinatory.

Divination hath been anciently and fitly divided into artificial and natural; whereof artificial is when the mind maketh a prediction by argument, concluding upon signs and tokens: natural is when the mind hath a presention by an internal power, without the inducement of a sign. [Francis Bacon, "The Advancement of Learning," 1605]

divine (v.)

late 14c., divinen, "learn or make out by or as if by divination, foretell" future events (trans.), also intransitive, "use or practice divination;" from Old French deviner, from Vulgar Latin *devinare, a dissimilation of Latin divinare "foresee, foretell, predict," from divinus "of a god," from divus "of or belonging to a god, inspired, prophetic," which is related to deus "god, deity" (from PIE root *dyeu- "to shine," in derivatives "sky, heaven, god").

Latin divinus also meant, as a noun, "soothsayer." English divine (v.) is also attested from late 14c. in the sense of "make out by observations or otherwise; make a guess or conjecture" without reference to supernatural insight. The earliest English sense is "to contrive, plot" (mid-14c.). Related: Divined; divining. Divining rod (or wand) is attested from 1650s.

The general sense of "straight line about which parts are arranged" is from 1660s.

orient (n.)

late 14c., "the direction east; the part of the horizon where the sun first appears," also (now with capital O-) "the eastern regions of the world, eastern countries" (originally vaguely meaning the region east and south of Europe, what is now called the Middle East but also sometimes Egypt and India), from Old French orient "east" (11c.), from Latin orientem (nominative oriens) "the rising sun, the east, part of the sky where the sun rises," originally "rising" (adj.), present participle of oriri "to rise" (see origin).

Meaning "a pearl of the first water" is by 1831, short for pearl of the Orient (late 14c.) originally meaning one from the Indian seas. Hence also the meaning "a delicate iridescence, the peculiar luster of a fine pearl" (1755). The Orient Express was a train that ran from Paris to Istanbul via Vienna 1883-1961, from the start it was associated with espionage and intrigue.

No apparent connections outside Germanic. "English alone has retained the word in a general sense, for which the other languages use forms corresponding to OE. þæc thatch" [OED].

lurid (adj.)

1650s, "pale, wan," from Latin luridus "pale yellow, ghastly, the color of bruises," a word of uncertain origin and etymology, perhaps cognate with Greek khlōros "pale green, greenish-yellow" (see Chloe), or connected to Latin lividus (see livid).

It has more to do with the interplay of light and darkness than it does with color. It suggests a combination of light and gloom; "Said, e.g. of the sickly pallor of the skin in disease, or of the aspect of things when the sky is overcast" [OED]; "having the character of a light which does not show the colors of objects" [Century Dictionary]. Meaning "glowing in the darkness" is from 1727 ("of the color or appearance of dull smoky flames" - Century Dictionary]. In scientific use (1767) "of a dingy brown or yellowish-brown color" [OED]. The figurative sense of "sensational" is first attested 1850, via the notion of "ominous" (if from the flames sense) or "ghastly" (if from the older sense). Related: Luridly.

Arctic Circle 

1550s in astronomy, in reference to a celestial circle, a line around the sky which, in any location, bounds the stars which are ever-visible from that latitude (in the Northern Hemisphere its center point is the celestial north pole); the concept goes back to the ancient Greeks, for whom this set of constellations included most prominently the two bears (arktoi), hence the name for the circle (see arctic). In Middle English it was the north cercle (late 14c.).

In geography, from 1620s as "the circle roughly 66 degrees 32 minutes north of the equator" (based on obliquity of the ecliptic of 23 degrees 28 minutes), marking the southern extremity of the polar day, when the sun at least theoretically passes the north point without setting on at least one summer day and does not rise on at least one winter one.

-ic 

Middle English -ik, -ick, word-forming element making adjectives, "having to do with, having the nature of, being, made of, caused by, similar to," from French -ique and directly from Latin -icus or from cognate Greek -ikos "in the manner of; pertaining to." From PIE adjective suffix *-(i)ko, which also yielded Slavic -isku, adjectival suffix indicating origin, the source of the -sky (Russian -skii) in many surnames. In chemistry, indicating a higher valence than names in -ous (first in benzoic, 1791).

In Middle English and after often spelled -ick, -ike, -ique. Variant forms in -ick (critick, ethick) were common in early Modern English and survived in English dictionaries into early 19c. This spelling was supported by Johnson but opposed by Webster, who prevailed.
