noun
the lowest point; point of greatest adversity or despair.
Nadir comes via Middle French and Late Latin nadir “point opposite the sun, point opposite the zenith” from Arabic naẓīr (as-samt) “opposite (the zenith).” Arabic samt is the source of zenith. Nadir (and zenith) entered English in the late 14th century.
At the nadir of the global stock market crash in March 2009, the kronor hit a low of 8.48 euro cents per kronor ….
… [the] fragment was hurled from what had seemed the nadir of horror to black, clutching pits of a horror still more profound.
noun
the transposition of letters, syllables, or sounds in a word, as in the pronunciation aks for ask.
In linguistics, metathesis is the transposition of two consecutive letters or sounds of a word, as in the now nonstandard pronunciation aks for ask (Old English has the verbs áscian and axian, and Middle English has asken and axen). Every well-disciplined schoolboy knows that in Greek quantitative metathesis is the change of long vowel + short vowel, e.g., ēo, to short vowel + long vowel, eō. Metathesis comes via Late Latin metathesis “transposition of the letters of a word,” from Greek metáthesis “change, change of position, transposition,” a compound formed of the common Greek preposition and prefix metá, meta– “with, in the middle of, among” (metá is related to German mit and Old English mid “with,” as in the first syllable of midwife). Thésis “placing, location, setting” is a derivative of the verb tithénai “to put, place,” from the very common Proto-Indo-European root dhē– “to place, put,” and the source of Latin facere “to do” and English do. Metathesis entered English in the 16th century.
”NOO-kyuh-luhr”-sayers, who number in the many millions, in fact, move the l in nuclear to the final syllable and thus avoid the unusual pattern. (Linguists refer to this sound-switching process as metathesis.)
Remember this when the next time you hear someone complaining about aks for ask or nucular for nuclear, or even perscription. It’s called metathesis, and it’s a very common, perfectly natural process.
adjective
British Slang.
exhausted; very tired: He is really knackered after work.
The verb knacker originally meant “to tire, kill, castrate,” a verb derived either from the noun knacker “a tradesman who buys animal carcasses or slaughters useless livestock” or from the plural noun knackers, a slang word for “testicles, courage.” Knackered in the sense “exhausted” entered English in 19th century.
She was completely knackered. All she wanted was a shower and twelve hours of sleep.
When they’re knackered like that they start crying.
