unselfishly concerned for or devoted to the welfare of others.
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.
Ethics asks us to critically reflect on our judgments to determine the right thing to do. When Dr. Martin Luther King in his 1963 sermon concluded that to be a good neighbor was to be altruistic, he asked us to be willingly obedient to unenforceable obligations.
surrounding a star.
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.
When stars are still very young (only a few million years old), their circumstellar disks are relatively huge, often with about 1 to 10 percent of the mass of the central star in a typical system. For a star like the sun, that amounts to a disk with roughly 100 times the mass of Jupiter.
In the circumstellar shells, which are shells of gas now surrounding the star, you can have dust particles form because the temperature and density are perfect for making dust. This dust then gets kicked back out into the interstellar medium along with gas and that is what the next generation of stars will form from.
tending to a violet color.
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.
Fashion Week in New York started on Thursday with designer runways shrouded in gray …. Occasional breaks in the overcast tones on the catwalks brought flashes of burgundy and teal, although the go-to color of the day was purple. Violescent dresses, skirts and shirts were paired with black-and-white coordinating pieces by Richard Chai Love. The designer cut lavender damask into dresses, coats and suits. Nicholas K, meanwhile, showed a handful of smoky mauve fashions, including a luscious knitted wrap and a luminescent jacket.
The sudden alternations of warm light and cold shade made him shiver. In front of the Palazzo di Venezia, and in front of the Gesu, it had seemed to him as if all the night of ancient times were falling icily upon his shoulders; but at each fresh square, each broadening of the new thoroughfares, there came a return to light, to the pleasant warmth and gaiety of life. The yellow sunflashes, in falling from the house fronts, sharply outlined the violescent shadows. Strips of sky, very blue and very benign, could be perceived between the roofs.
