very productive or creative intellectually: the fecund years of the Italian Renaissance.
The English adjective fecund ultimately comes from Latin fēcundus “fertile, productive,” used of humans, animals, and plants. The first syllable fē– is a Latin development of the Proto-Indo-European root dhē(i)– “to suck, suckle.” From fē– Latin forms the derivatives fēlīx “fruitful, productive, fortunate, blessed, lucky” (source of the English name Felix and felicity), fēmina “woman” (originally a feminine participle meaning “suckling”), fētus “parturition, birth, conception, begetting, young (plant or animal), child,” and fīlius and fīlia “son” and “daughter,” respectively (and source of filial). Dhē(i)– appears in Greek as thē(i)-, as in thêsthai “to suckle” and thēlḗ “nipple, teat” (an element of the uncommon English noun thelitis “inflammation of the nipple”). Fecund entered English in the 15th century.
… he possesses a fecund imagination able to spin out one successful series after another ….
He sort of reminded me of Billy Name … the guy who pretty much functioned as the Factory’s foreman during its most fecund years.
Jactation comes straight from the Latin noun jactātiōn– (the inflectional stem of jactātiō) “a flinging or throwing about, a shaking or jolting, tossing of the waves at sea,” and by extension, “frequent changing of one’s mind or attitude, boastfulness, grounds for boasting.” Jactātiō is a derivative of the verb jactāre “to throw, hurl, toss,” a frequentative verb from jacere “to throw, toss, sow (seed), cast (anchor).” Jactation entered English in the 16th century.
Judge of my mortification, t’other day, when in a moment of jactation, I boasted of being born in that illustrious, ancient, and powerful kingdom!
Others see in them merely the jactation of a limited wit, which is nothing more.
verb (used with object)
to undo the invention of; to reverse the existence of.
Disinvent is an obvious compound of the prefix dis-, here having a reversing force, and the verb invent. It is quite rare, first appearing in the second half of the 19th century (for the “disinventing” of the telegraph). In the 20th century disinvent has been applied to the impossibility of “disinventing” nuclear or chemical weapons.
However alarmed we are by those weapons, we cannot disinvent them. The world cannot cancel the knowledge of how to make them. It is an irreversible fact.
A number of science fiction movies have actually had to “disinvent” existing technologies in order to retell the myth of how rebels against “the system” help preserve free and open societies.
