More about nugatory
Nugatory 鈥渙f no force or effect鈥� comes from Latin 苍奴驳腻迟艒谤颈耻蝉 鈥渨orthless, useless,鈥� from the verb 苍奴驳腻谤墨 鈥渢o trifle.鈥� 狈奴驳腻谤墨, in turn, derives from the plural noun 苍奴驳补别 鈥渢rifles, idle talk, frivolities,鈥� which is also the source of nugacious, a synonym of nugatory, and nugacity, a noun that means 鈥渋nsignificance.鈥� While it may seem odd that Latin features nouns such as 苍奴驳补别 that always appear in the plural, English is no stranger to nouns that usually or exclusively appear in plural form. Many objects that contain two component parts, such as pants, trousers, scissors, and shears, are typically limited to the plural, as are certain location-related words, such as headquarters and surroundings. Nugatory was first recorded in English at the turn of the 17th century.

I am sending you herewith photo and description of our pressure testing machine. It is our belief that the method and construction employed entirely avoid errors from the following sources: (1) Variation in wind velocity; (2) Variations in temperature and density of the atmosphere; (3) Travel of center of pressure; (4) Variation in angle of incidence owing to movements of the mounting arms, The first two causes gave Mr. Langley trouble; while the third and fourth vitiate somewhat the natural wind experiments of Lilienthal. Gravity and centrifugal force are also rendered nugatory.
While outdated theory may not render one’s interpretations nugatory, they may seem quaint to those who work within the field from which the ideas came, and intramural strife, if it remains unobserved, can not then serve to provide occasions for fruitful comparison, since intellectual battles in one arena often have interesting parallels and previously unimagined consequences within another.

circadian
adjective
noting or pertaining to rhythmic biological cycles recurring at approximately 24-hour intervals.
More about circadian
Circadian 鈥減ertaining to 24-hour biological cycles鈥� is a coinage based on two Latin terms: the preposition 肠颈谤肠腻 鈥渁bout, around鈥� and 诲颈脓蝉 鈥渄ay.鈥� English has also adapted 肠颈谤肠腻 directly (as circa) when providing estimates of dates. If you were wondering why 肠颈谤肠腻 resembled circle and circus, it is because all three words descend from Ancient Greek 办铆谤办辞蝉 鈥渞ing, circle.鈥� Latin 诲颈脓蝉 is also the source of day-related words such as diary, diet, and meridian; the term also has an adjective form, diurnus 鈥渄aily,鈥� which is the source of words such as diurnal and journal, as we learned about in the etymology for the recent 51吃瓜 of the Day selection toujours perdrix. Circadian was first recorded in English in the late 1950s.

Think of every cell and system in your body as having a tiny clock. And each of these tiny clocks is on approximately a 24-hour cycle, so a master clock in your brain coordinates and makes sure those tiny clocks work together. This 鈥�circadian system鈥� essentially signals to your body what time of day it is and what time of year it is and helps match your behavior with your environment.
Sleep seems to remove us from the general tyranny of the advancing clock. When you wake, 20 minutes could have passed as easily as three hours. But sleep defines time, dividing day and night. Humans discover circadian rhythm through the urge to sleep. That urge is, of course, cyclic, endless: always more sleep to be had.

avgolemono
noun
a soup or sauce made with beaten eggs, lemon juice, and usually chicken broth.
More about avgolemono
Avgolemono 鈥渁 soup made with beaten eggs, lemon juice, and chicken broth鈥� is a loanword from Modern Greek 补耻驳辞濒茅尘辞苍辞, literally meaning 鈥渆gg lemon.鈥� Through a series of regular yet dramatic sound changes, Modern Greek 补耻驳贸 derives from classical Greek 艒颈贸苍 鈥渆gg,鈥� which is the source of the combining form oo- (as in oocyte 鈥渋mmature egg cell鈥�) and is distantly related to English egg and Latin ovum (as in ovary and, via Spanish, in huevos rancheros). Modern Greek 濒别尘贸苍颈, bucking the common trend of Greek words exported to the Italian peninsula, is a borrowing from Italian limone and ultimately derives from Persian 濒墨尘奴; from here, the word may have traveled through India and originated in Southeast Asia, perhaps in the Austronesian language family. Avgolemono was first recorded in English in the early 1960s.
how is avgolemono used?
Avgolemono is the most famous Greek sauce, named for its indispensable ingredients, avgo (egg) and lemoni (lemon). Light in color and of the prized lemony flavor, it is prepared with or without a roux base. But egg, lemon juice, and hot stock or broth from the dish for which it is being prepared are necessities .鈥� Some Greek villagers, when adding the avgolemono to soup or dish, make a kissing sound, a magical trick to keep the egg from curdling.
“How do you like the avgolemono?” Mrs. Redbone asks Wakefield. “They say it was first served at the table of Aristophanes after he wrote a play about the meeting of a chicken and a lemon.” “That’s lovely,” interjects Persephone. “I thought it was first served at the Greek diner on Twenty-third Street where I first had it.” Avgolemono is a lovely soup, light, pale as the crest of a wave, filled with sun, the rice like grains of sand on the beach at Kios. I must be getting soft, thinks Wakefield: I’m making soup metaphors. I’ve got to toughen up.
