the largest moon of the planet Jupiter.
Ganymede is named for a teenage boy in Greek mythology whom the gods chose, because of his beauty, to be their cup-bearer. One possibility is that Ganymede comes from the Greek words gánymai, “to be glad,” and mḗdea, “art, counsel, plans.” The second of these elements is also the origin of numerous names of Greek origin that contain med-, such as Archimedes and Medea. Ganymede was first recorded in English in the 1550s. EXAMPLE OF GANYMEDE USED IN A SENTENCE Though Galileo discovered Ganymede, his telescope was far too weak to detect the craters and ice that cover the moon’s surface.
environmental design of residential and park land using various methods for minimizing the need for water use.
Xeriscaping, “environmental design based on minimal water use,” is based on xeric, “of a dry environment,” on the pattern of landscaping. Xeric comes from Ancient Greek xērós, “dry,” which resembles English sere, “dry,” and the Word of the Day rizzar, but this resemblance is purely coincidental. Though landscape comes from the Dutch equivalents of land and -ship, landscaping was falsely analyzed as land compounded with “scaping,” with a sense roughly like “aesthetic improvement of a space,” and combined with xeri- to form today’s word. A similar phenomenon happened with hamburger, which literally means “of Hamburg” but was falsely analyzed as ham compounded with “burger,” with a sense roughly like “patty on a bun,” and combined with cheese to form cheeseburger. Xeriscaping was first recorded in English in the early 1980s. EXAMPLE OF XERISCAPING USED IN A SENTENCE Xeriscaping transformed their rugged yard into an oasis.
to subject to the action of x-rays.
Roentgenize, “to subject to the action of X-rays,” is named for Wilhelm Conrad Röntgen (1845–1923), who discovered X-rays in 1895. As we learned from the Word of the Day foehn, oe is an alternative way of representing ö in German when the umlaut (the horizontal pair of dots, also known as a dieresis) is not readily available. The same applies to German ä and ü, which may be written as ae and ue; compare the Word of the Day gemütlich. The surname Röntgen is, unfortunately for us language detectives, of uncertain origin. Roentgenize was first recorded in English in the late 1890s. EXAMPLE OF ROENTGENIZE USED IN A SENTENCE After Wilhelm Röngten roentgenized the hand of his wife, Anna, she examined her finger bones in the resulting image and chillingly remarked, “I have seen my death.”
mildness; gentleness.
Mansuetude, “mildness, gentleness,” comes from Latin mānsuētūdō, which is equivalent to manus, “hand”; suēscere, “to become accustomed”; and -tūdō, a noun-forming suffix similar to English -hood and -ness. Manus is also the source of manacle, manicure, manual, and the Word of the Day mano a mano. Suēscere, which contains the common element -sc-, “to become” (see the Word of the Day opalesce), is related to Ancient Greek êthos, “custom, habit,” as in ethics. Mansuetude was first recorded in English in the late 14th century. EXAMPLE OF MANSUETUDE USED IN A SENTENCE Every day on the job, teachers have to balance strictness with mansuetude as they lead their students through lessons.
engagement to be married; betrothal.
Trothplight, “engagement to be married,” is a compound of troth, “faithfulness, truth, promise,” and plight, “pledge.” Troth, which is also found in betroth, “to arrange for the marriage of,” shares an origin with truce, true, truth, and trust and comes from a root meaning “firmness,” both literal and figurative. This literal sense is why the root also appears in words relating to wood, such as English tree as well as Ancient Greek déndron, “tree” (as in rhododendron), and drŷs, “tree, oak” (as in dryad). Trothplight was first recorded in English in the early 14th century. EXAMPLE OF TROTHPLIGHT USED IN A SENTENCE After a trothplight of unclear length, Anne Hathaway and William Shakespeare were married in 1582.
