The Greek noun órganon means “tool, instrument, sensory organ, body part, musical instrument (whence the English name of the musical instrument), surgical instrument, table of calculations, (a concrete) work, work product, and a set of principles for conducting scientific and philosophical work.” This last meaning first occurs in the works of the Peripatetic philosopher Alexander of Aphrodisias, who lived in the late 2nd and early 3rd centuries a.d. and was the most famous ancient Greek commentator on Aristotle. Órganon is a derivative of the Greek root erg-, org– (also dialectal werg-, worg-), from the Proto-Indo-European root werg-, worg-; the Germanic form of this root is werk-, whence English work. Organon in its sense “bodily organ” entered English in the late 16th century; the philosophical sense entered English in the early 17th century.
… for genuine proof in concrete matter we require an organon more delicate, versatile, and elastic than verbal argumentation.
It [logic] thus sunk into the position of an Organon or instrument.

The English adjective vigesimal comes from the Latin adjectives vīgēsimus and vīcēsimus (also vīcēnsimus) “twentieth.” There is an obvious connection in meaning between the adjectives and the Latin numeral vīgintī “twenty,” but there is also an obvious difficulty in form. The fluctuation between –g– and –c– in the Latin words has never been satisfactorily explained, as the expected Latin form would be vīcintī. Vigesimal entered English in the 17th century.
Maya numeral systems were vigesimal (base twenty), counted by twenties, four hundreds, eight thousands, and so on, rather than by tens, hundreds, and thousands as in a decimal system.

The verb bombinate comes from Latin bombināre “to buzz,” a possible variant or corruption of bombilāre, bombitāre, or bombīre “to buzz, hum,” all derivatives of the noun bombus “a buzzing, humming.” The Latin verbs and noun ultimately come from Greek bómbos “a humming, buzzing” and its various derivative verbs. The specific form bombināre is apparently a coinage by the French satirist François Rabelais (c1494–1553) in a Renaissance Latin parody of scholastic Latin in the Middle Ages. Bombinate entered English in the second half of the 19th century.
… and then we were off, climbing rapidly to a couple of thousand feet, then making course west, bombinating over the voes (small fjords) and sounds that fretwork the Shetland coastline.
