Word of the Day

Epicurean “fond of or adapted to luxury or indulgence in sensual pleasures” derives via Middle English from Latin Epicūrēus “of Epicurus.” Epicurus (in the original Ancient Greek, Epíkouros) was a philosopher of Athenian origin who flourished in the late 4th and early 3rd centuries BC, and his school of thought, Epicureanism, had as its foundation the belief that pleasure was most important. The name Epicurus comes from the Ancient Greek adjective epíkouros “assisting,” which also functions as a noun meaning “ally, helper.” Epicurean was first recorded in English in the late 1300s.

Firth “a long, narrow indentation of the seacoast” is a Middle English adaptation of the Old Norse term fjǫrthr (stem firth-), which became Norwegian fjord and was later borrowed into modern English. In this way, firth and fjord are doublets, which are pairs or groups of words in a language that are derived from the same source but through different routes. Other doublets in English include plant and clan (both from Latin planta “scion, plant,” but the latter via Irish Gaelic) as well as apothecary, bodega, and boutique (all from Ancient Greek apothḗkē “shop”). Recent Word of the Day gramarye, for example, is a doublet of both glamour and grammar; all three words come from Old French gramaire “grammar” but through different routes. Firth was first recorded in English in the early 1400s.

Altruistic “unselfishly concerned for or devoted to the welfare of others” is formed from the altru- element in the term altruism plus the adjectival suffix -istic. Altruism, based on literary French autrui “others,” ultimately comes from Latin alter “(of two) the other,” which is also the source of English words such as alteration, altercation, and alternation, all of which involve a change into or an exchange with another entity, version, or individual. Altruistic behaviors, such as helping those in need, are often contrasted with egoistic behaviors, which prioritize a person’s own desires over the needs of others. While egoism, also known as egotism, is selfishness, altruism is selflessness. Altruistic was first recorded in English in the early 1850s.

Circumstellar “surrounding a star” is a compound of the element circum- “around” and the adjective stellar “of or relating to the stars.” Circum- comes from Latin circus “circle,” which is the source of English terms such as circa, circle, circular, circumference, circus, and the recent Word of the Day circadian. Latin has two words meaning “star”—sīdus (stem sīder-) and stella. Sīdus largely died out except in technical terms such as sidereal “determined by the stars,” while stella is the source of stellar, constellation, interstellar, and modern Romance words for “star,” such as French étoile and Spanish estrella. Circumstellar was first recorded in English in the early 1950s.

Violescent “tending to a violet color” derives from the Latin noun viola “violet” and the inchoative suffix -escent “becoming, starting to be,” as we learned about from the recent Word of the Day evanesce. Viola is of uncertain origin but appears to have a cognate in Ancient Greek: íon “violet.” Ancient Greek once had a letter called wau or digamma, which made the “w” sound and looked like the Roman letter F, but eventually lost the letter entirely; this is how earlier wíon became íon while the “w” was preserved as “v” in Latin viola. A similar phenomenon happened with Ancient Greek oînos (earlier woînos) and Latin vīnum “wine” as well as Ancient Greek elaíā (earlier elaíwā) and Latin olīva “olive.” Violescent was first recorded in English in the 1840s.
