hex

[heks]

verb (used with object)

to bewitch; practice witchcraft on.

Explanation

Hex “to bewitch” is a borrowing via Pennsylvania Dutch from German hexen, related to the noun Hexe “witch.” Hexe is a cognate of the English word hag “witch, sorceress; ugly old woman,” and the two are shortened from Old High German hagazussa and Old English hégtesse, respectively. Though hex and hag have long had negative connotations in English because of their magical associations, theories about their origin are far less biased; the haga-/hég- element may derive from a root meaning “able, skilled” or could be connected to hawthorn, hay, and hedge, thereby reflecting a historical link between plants and sorcery. The -zussa/-tesse element, in turn, may be related to a variety of words in the Indo-European language family with meanings such as “fairy,” “ghost,” and “demon.” Hex was first recorded in English in the 1820s.

fartlek

[fahrt-lek]

noun

a training technique, used especially among runners, consisting of bursts of intense effort loosely alternating with less strenuous activity.

Explanation

Fartlek “a training technique consisting of bursts of intense effort” is a direct borrowing from Swedish and comprises the elements fart “speed” and lek “play.” Fart is cognate with the English verb fare “to go, travel,” as found in the nouns warfare, wayfarer, and welfare, from a Proto-Indo-European root per- “to pass over.” Other derivatives from this root include port, portable, and portal (via Latin porta “door, gate” and portāre “to carry”) and pore and emporium (via Ancient Greek póros “passage”). Lek may be related to English lark “a carefree adventure; to have fun” but has a far more popular relative: LEGO, the name of a brand of interlocking plastic bricks, from Danish leg godt “to play well.” Fartlek was first recorded in English in the 1950s.

toujours perdrix

[too-zhoor per-dree]

too much of a good thing.

Explanation

Toujours perdrix “too much of a good thing” is a direct borrowing of two French words: toujours “always” and perdrix “partridge.” Toujours derives from an Old French phrase meaning “all days” and is equivalent to Modern French tous jours. Tous (masculine singular tout) comes from Latin tƍtus “whole, entire,” which is also the source of total and the Italian flavor tutti frutti “all fruits,” while jours (singular jour) comes from Latin diurnus “daily, of the day,” derivatives of which include diurnal and journal. The phrase toujours perdrix is allegedly connected to King Henri IV of France, whose spiritual adviser loved to eat partridge but, upon being served partridge for every meal, grew tired, frustrated, and spiteful of the dish. Toujours perdrix was first recorded in English in the early 1800s.

armscye

[ahrm-sahy, -zahy]

noun

the armhole opening in a garment through which the hand, and then the arm, passes, and to which a sleeve may be attached.

Explanation

Armscye “the armhole opening in a garment” is a compound of arm and the Scots term scye “armhole.” Because scye is a borrowing from another dialect and of unknown origin, a common misinterpretation is that armscye derives from a phrase such as “arm’s eye.” This mistake is known as an eggcorn, which is a type of folk etymology that refers to the alteration of a word or phrase that has been misheard or misinterpreted. The word eggcorn itself comes from a mistaken belief that acorn, which is of Old English origin, is a recent compound of Modern English egg and corn. Other eggcorns that may ring a bell include free reign instead of the correct free rein and for all intensive purposes instead of the correct for all intents and purposes. Armscye was first recorded in English in the 1920s.

vespertine

[ves-per-tin, -tahyn]

adjective

of, relating to, or occurring in the evening.

Explanation

Vespertine “of, relating to, or occurring in the evening” derives from Latin vesper “evening,” which comes from a Proto-Indo-European root with the same sense. Through this root, vesper is a cognate of the English term west, with a shift in definition because of the direction of the sunset. As we learned with the recent Word of the Day aureate, which may be related to east and Latin aurƍra “dawn,” there is often an overlap between the cardinal directions and the location of the sun. Another distant relative of vesper is Ancient Greek hĂ©speros “evening,” and its derivative Hesperus “evening star” is a nickname for the planet Venus. Vespertine was first recorded in English at the turn of the 16th century.
