Word of the Day

Cantrip, “a magic spell,” may not be related to the English verbs can and trip, but that doesn’t mean that its origin is any clearer. One possibility is that cantrip is a variant of Old English calcatrippe, “caltrop,” with the shift from l to n resulting from dissimilation, as we learned about from ensorcell. Calcatrippe is equivalent to Latin calx, “spur, heel” (as in calcaneus, a bone of the heel), plus Old English træppe, “step” (compare modern English trap). Another possibility is that the can- element comes from Latin cantāre, “to sing,” (as in enchant, incantation, and past Word of the Day descant), while -trip element is related not to trap but rather to rope because ropelike objects are a common element in sorcery. Cantrip was first recorded in English in the 1710s.

Ensorcell, “to bewitch,” comes from Middle French ensorceler, of the same meaning, which is a dissimilated variant of ensorcerer. Dissimilation refers to when one of two identical sounds in a word happens to change, such as how colonel is pronounced “kur-nl” in US English and February often becomes “feb-yoo-er-ee”; without dissimilation, the two l’s in colonel and the two r’s in February would be preserved in speech.

Ensorcerer ultimately derives from Latin sors (stem sort-), “lot, fate.” Another descendant of sors today is French sortir, “to exit,” which comes via Latin sortīrī, “to cast lots,” perhaps with the influence of surgere (stem surrēct-), “to spring up, arise, stand up.” Ensorcell was first recorded in English circa 1540.

Selcouth, “strange, uncommon,” comes from Old English seldcūth, which is equivalent to seldan, “seldom,” and cūth, “couth, known, acquainted with.” Seldan has a number of relatives in other Germanic languages, including Dutch zelden, German selten, and Norwegian sjelden, but no known cognates outside the Germanic branch of the Indo-European language family. Cūth was the original past participle of can (Old English cunnan) before it evolved into Middle English coud, gained an l by analogy with should and would, and became could. Selcouth, as a word of Old English origin, was first recorded in English before 900 CE.

Tawpie, “a foolish young person,” comprises tawp-, an element of Scandinavian origin, and -ie, a diminutive suffix also found in dearie and sweetie. Tawp- is likely related to Danish tåbe, Norwegian tåpe, and Swedish tåp, all meaning “simpleton, fool,” from Old Norse. Because of the Vikings’ colonization of Scotland a millennium ago, numerous words of Norse origin became entrenched in the languages and dialects of Scotland. One such borrowing is kilt, which may be related to Norwegian kilte, “to bind, fasten up.” Tawpie was first recorded in English in the 1720s.

White hole is named by analogy after black hole. White is related to German weiß and Swedish vit, while the words for “white” in many Romance languages (including French blanc, Italian bianco, Portuguese branco, and Spanish blanco) are related to English blank. Russian astrophysicist Igor Novikov first presented his theory about white holes in the mid-1960s. EXAMPLE OF WHITE HOLE USED IN A SENTENCE While black holes are known for swallowing all energy and matter nearby, white holes are essentially their Bizarro World counterparts and do the opposite. FUN FACT ABOUT WHITE HOLE White holes are theorized to be the exit point of a wormhole—matter would enter a black hole at one point in the universe, move through a tunnel, and exit at a completely different point in the universe through a white hole.
