tektite: a glassy body of probably meteoritic origin and of rounded but indefinite shape. “Most geologists have long thought the tektites were terrestrial material thrown into the sky when a comet or asteroid struck earth and streamlined by their flight through the atmosphere while still molten.” — Nov. 28, 1989

wirrah: an Australian spotted food fish. “If you’re heading down near the reefs you might catch wirrah, but folks call it ‘old boot’ because it tastes about that.”

sirtaki: a Greek circle dance similar to a hora. “Senator Henry M. Jackson danced the sirtaki at a Greek‐American gathering in Newton, Mass., after addressing the crowd.” — Jan. 25, 1976

impayable: priceless, invaluable. “The credit card commercials always ended with a sort of punchline where they would list prices and then say something at the end was impayable.”

Micawber: someone who is poor but optimistic. “In ‘David Copperfield,’ the poor, prolix and tragicomically positive Wilkins Micawber is uplifted by a humble gin punch.” — Dec. 9, 2016

escharotic: producing an eschar (a scab formed especially after a burn). “Under the agonies of the ague, the typhus, or the gout — through the wearisome days and nights of consumption — under the knife or the escharotic, under all assaults of the Imperial Destroyer — we confidingly look to him for recovery or relief.” — Oct. 18, 1860

bourgade: a village of scattered dwellings, an unfortified town. “Despite the problems caused by dragons, winter monsters and irresponsible feuding lords, the people of Westeros rebuilt one bourgade after another without much of a plan for defense.”

chatoyance: the state of being chatoyant (having a changeable luster or color with an undulating narrow band of white light). “What I am asserting is that Brigid Brophy’s fey mannerisms betray her message and her message sinks her showy technique; what should be all restless chatoyancy becomes a fixed light blinking code.” — July, 16, 1978

bebung: a tremolo effect similar to a violin vibrato and produced on a clavichord by sustaining a varying pressure on the key. “Funnily enough, the score repeatedly notates an ornament that simply can’t be achieved on a modern piano: a bebung, which is a form of vibrato.” — Jan. 18, 2022

obstropolous: a dialectical variant of obstreperous (being unruly or resistant to control). “Long’s field mouse scolds, ‘Nonsense!’ when Thumbelina objects to spending her life underground with the pompous blind mole. Alderson’s snaps, ‘Now don’t be obstropolous.’” — April 11, 2010

noctivagant: going about in the night; night-wandering. “The couple believed their cat was a sleepy, cuddly companion, when in fact she was simply resting at day to dart away in the dark, a noctivagant terror to mice, pigeons and the downstairs neighbor, who shut his window tight once the sun slipped out of sight.”
