floccinaucinihilipilification (n.)youdaoicibaDictYouDict
"action or habit of estimating as worthless," in popular smarty-pants use from c. 1963; attested 1741 (in a letter by William Shenstone, published 1769), a combination of four Latin words (flocci, nauci, nihili, pilifi) all signifying "at a small price" or "for nothing," which appeared together in a rule of the well-known Eton Latin Grammar.
[F]or whatever the world might esteem in poor Somervile, I really find, upon critical enquiry, that I loved him for nothing so much as his flocci-nauci-nihili-pili-fication of money. [Shenstone, letter, 1741]
The kind of jocular formation that was possible among educated men in Britain in those days. Just so, as in praesenti, the opening words of mnemonic lines on conjugation in Lilley's 16c. Latin grammar, could stand alone as late as 19c. and be understood to mean "rudiments of Latin."
rudiment (n.)youdaoicibaDictYouDict
1540s, from Middle French rudiment (16c.) or directly from Latin rudimentum "early training, first experience, beginning, first principle," from rudis "unlearned, untrained" (see rude). Related: Rudiments.
stamina (n.)youdaoicibaDictYouDict
1670s, "rudiments or original elements of something," from Latin stamina "threads," plural of stamen (genitive staminis) "thread, warp" (see stamen). Sense of "power to resist or recover, strength, endurance" first recorded 1726 (originally plural), from earlier meaning "congenital vital capacities of a person or animal;" also in part from use of the Latin word in reference to the threads spun by the Fates (such as queri nimio de stamine "too long a thread of life"), and partly from a figurative use of Latin stamen "the warp (of cloth)" on the notion of the warp as the "foundation" of a fabric. Related: Staminal.
