ferrule

[fer-uhl, -ool]

noun

a ring or cap, usually of metal, put around the end of a post, cane, or the like, to prevent splitting.

Explanation

To the casual observer, ferrule “a ring or cap put around the end of something” looks like it is a compound of Latin ferrum “iron” (compare the chemical symbol Fe and Spanish hierro) and the suffix -ule “small, little,” but looks can be deceiving. In fact, ferrule is an alteration of English forms such as verrel or virl, with a spelling change based simply on an association with Latin ferrum. Verrel and virl derive from Latin viriola “small bracelet,” from viria “bracelet,” a word of Gaulish (continental Celtic) origin. As we learned from the recent Word of the Day cathartic, it is rather common to see folk etymology—spelling and pronunciation changes based on associations with unrelated words—at work in many languages. In English, folk etymology explains the spelling changes in words such as ferrule as well as author (by influence of authentic), gridiron (by influence of iron), and rosemary (by influence of rose and the name Mary). Ferrule was first recorded circa 1610.

cenote

[suh-noh-tee]

noun

a deep natural well or sinkhole, especially in Central America, formed by the collapse of surface limestone that exposes groundwater underneath.

Explanation

Cenote “a deep natural well or sinkhole” is a loanword from Mexican Spanish and derives from the word tz’onot in the Yucatec Mayan language. A common misconception is that Mayan is a single language, but it is in fact a language family comprising at least 20 languages that are spoken primarily in Belize, Guatemala, and southeastern Mexico. Yucatec Mayan is one of the best-known Mayan languages and has hundreds of thousands of speakers today in the YucatĂĄn Peninsula of Mexico, while QuichĂ© (also K’iche’) is the most spoken Mayan tongue, with more than 1 million speakers in Guatemala. Though the Mayan languages share numerous grammatical features with other language families found in Mesoamerica, these similarities are most likely the result of language contact rather than a shared origin. Cenote was first recorded in English circa 1840.

démodé

[dey-maw-dey]

adjective

no longer in fashion; out of date; outmoded.

Explanation

DĂ©modĂ© “no longer in fashion” is a borrowing of the past participle of the French verb dĂ©moder “to put out of fashion.” DĂ©moder is based on the noun mode “fashion,” which also appears in the expression Ă  la mode, which in English often means “served with a scoop of ice cream” but literally translates as “in the fashion.” French mode derives from Latin modus, a word with a wide range of meanings, such as “manner,” “measure,” “limit,” and even “rhythm.” To see the “manner” sense in action, compare the Latin-origin phrases modus operandi (or M.O.) “one’s usual way of doing something” and modus vivendi “lifestyle.” DĂ©modĂ© was first recorded in the late 19th century.

tour de force

[toor duh -fawrs]

noun

a feat requiring unusual strength, skill, or ingenuity.

Explanation

Tour de force “a feat requiring unusual strength, skill, or ingenuity” is a borrowing from French, in which the phrase literally means “turn of strength.” French tour has two separate derivations: the noun tour “a turn” in tour de force is related to the verb tourner “to turn” (from Latin tornāre), and this tour is not to be confused with tour “tower” (from Latin turris). This distinction is why the Tour de France refers to a long, winding bicycle race while the tour Eiffel is the original French name for the Eiffel Tower. Other derivatives of Latin tornāre “to turn” include return, tourniquet, tourist, and tornado. Tour de force was first recorded in English circa the year 1800.

azimuth

[az-uh-muhth]

noun

the arc of the horizon measured clockwise from the south point, in astronomy, or from the north point, in navigation, to the point where a vertical circle through a given heavenly body intersects the horizon.

Explanation

Azimuth “the arc of the horizon measured clockwise” derives by way of Middle French azimut from Arabic as-sumĆ«t “the ways,” an assimilated plural form of al-samt “the way.” As we learned from the recent Word of the Day acequia, the prefix al- “the” assimilates to match the first sound in the word that follows—but only when that sound is pronounced with the tip of the tongue. Azimuth shares an origin with zenith “the point on the celestial sphere vertically above a given position,” but while azimuth closely resembles its Arabic source, zenith arose when Arabic samt was borrowed into Old Spanish as zemt and was subsequently misread as zenit. We never know when a small scribal error can end up creating a new word! Azimuth was first recorded in English in the late 14th century.
