"Fans who attend Double-A games this year will see a couple of new rules…. During the first half of the season, all infielders must have their feet on the dirt when a pitch is thrown, attenuating the major defensive shifts that have become prevalent in baseball in recent years, and in the season's second half, no shifting will be permitted at all." — Ryan Anderson, The Daily Citizen-News (Dalton, Georgia), 15 Apr. 2021

Did You Know?

Attenuate ultimately comes from a combining of the Latin prefix ad-, meaning "to" or "toward," and tenuis, meaning "thin," a pedigree that is in keeping with the English word's current meanings, which all have to do with literal or metaphorical thinning. The word is most common in technical contexts, where it often implies the reduction or weakening of something by physical or chemical means. You can attenuate wire by drawing it through successively smaller holes, for example, or attenuate gold by hammering it into thin sheets. Current evidence dates the term to the 16th century, in which we find many references to bodily humors in need of being attenuated; modern medicine prefers to use the word in reference to procedures that weaken a pathogen or reduce the severity of a disease.

Attenuate 終極來自拉丁語前綴 ad-（意思是“to「向」”或“toward「向」”）和tenuis（意思是“thin「薄」”）的組合，與英語單詞的如今涵義一律，都與字面上或隱喻上的變薄有關(guān)。 這個詞在科武藝語中最稀有，它通常意味著經(jīng)過物理或化學(xué)伎倆變小或減弱某物質(zhì)。 您可以經(jīng)過將金屬絲不休地拉過更小的孔來使金屬絲變細，比如，經(jīng)過錘擊黃金來使它變薄。 現(xiàn)在的證據(jù)可以追溯到 16 世紀(jì)，我們在此中發(fā)覺了很多必要變小的bodily humors的參考材料； 古代醫(yī)學(xué)更喜好使用這個詞來指代減弱病原體或減小疾病嚴(yán)峻度的步驟。
