zoo-
word-forming element meaning "animal, living being," from Greek zoion "an animal," literally "a living being," from PIE root *gwei- "to live" (source also of Greek bios "life").
zek (n.)
"Russian condemned person in a prison or labor camp," 1968, from Russian zek, probably representing a vocalization of z/k, abbreviation of zaklyuchennyi "prisoner."
Zend (n.)
1715, "Parsee sacred book" (in full, Zend-Avesta, 1620s), from Old Persian zend, from Pahlavi zand "commentary," from Avestan zainti- "knowledge," from PIE root *gno- "to know." First used 1771 in reference to the language of the Zend-Avesta by French scholar Abraham Hyacinthe Anquetil-Duperron (1731-1805).
zenith (n.)
"point of the heavens directly overhead at any place," late 14c., from Old French cenith (Modern French zénith), from Medieval Latin cenit, senit, bungled scribal transliterations of Arabic samt "road, path," abbreviation of samt ar-ras, literally "the way over the head." Letter -m- misread as -ni-. The Medieval Latin word could as well be influenced by the rough agreement of the Arabic term with classical Latin semita "sidetrack, side path" (notion of "thing going off to the side"), from se- "apart" + *mi-ta-, a suffixed form of PIE root *mei- (1) "to change, go, move." Figurative sense of "highest point or state" is from c. 1600.
zeugma (n.)
1580s, "a single word (usually a verb or adjective) made to refer to two or more nouns in a sentence" (but properly applying to only one of them), from Greek zeugma, "a zeugma; that which is used for joining; boat bridge," literally "a yoking," from zeugnynai "to yoke" (from PIE root *yeug- "to join").
Zeus
supreme god of the ancient Greeks and master of the others, 1706, from Greek, from PIE *dewos- "god" (source also of Latin deus "god," Old Persian daiva- "demon, evil god," Old Church Slavonic deivai, Sanskrit deva-), from root *dyeu- "to shine," in derivatives "sky, heaven, god." The god-sense is originally "shining," but "whether as originally sun-god or as lightener" is not now clear.
zloty (n.)
monetary unit of Poland, 1842, from Polish złoty, literally "of gold," from złoto "gold," related to Russian zoloto, Czech zlato "gold," from suffixed form of PIE root *ghel- (2) "to shine," with derivatives denoting gold (the "bright" metal); see gold.
zoanthropy (n.)
form of insanity in which a man imagines himself to be another type of beast, 1845, from French zoanthrope or directly from Modern Latin zoanthropia, from Greek zoion "animal" (from PIE root *gwei- "to live") + anthropos "man" (see anthropo-).
zodiac (n.)
late 14c., from Old French zodiaque, from Latin zodiacus "zodiac," from Greek zodiakos (kyklos) "zodiac (circle)," literally "circle of little animals," from zodiaion, diminutive of zoion "animal" (from PIE root *gwei- "to live"). Libra is not an animal, but it was not a zodiac constellation to the Greeks, who reckoned 11 but counted Scorpio and its claws (including what is now Libra) as a "double constellation." Libra was figured back in by the Romans. In Old English the zodiac was twelf tacna "the twelve signs," and in Middle English also Our Ladye's Waye and the Girdle of the Sky.

The 10c. Anglo-Saxon treatise on astronomy translates Latin quinque zonas as fyf gyrdlas.
