1520s, in the grammatical sense, "inflect (a verb) through all its various forms," from Latin coniugatus, past participle of coniugare "to yoke together," from assimilated form of com "with, together" (see con-) + iugare "to join," from iugum "yoke" (from PIE root *yeug- "to join"). "This use has its origin in the fact that in inflected languages, a verb is conjugated by conjoining certain inflectional syllables with the root" [Century Dictionary]. Earlier as an adjective, "joined together" (late 15c.). Related: Conjugated; conjugating.
Proto-Indo-European root meaning "to join."

1808, from Italian improvisare "to sing or speak extempore," from Latin improviso "unforeseen; not studied or prepared beforehand," ablative of improvisus "not foreseen, unexpected," from assimilated form of in- "not, opposite of" (see in- (1)) + provisus "foreseen," also "provided," past participle of providere "foresee, provide" (see provide). Also partly from French improviser.
Regarded as a foreign word and generally printed in italics in English in early 19c. Other verbs were improvisate (1825), improvisatorize (1828), the latter from improvisator "one of a class of noted extemporaneous poets of Italy" (1765), the earliest word of the group to appear in English. Related: Improvised; improvising.
The metre generally adopted for these compositions was the ottava rima, although Doni affirms that the Florentines used to improvise* in all kinds of measure.
* This new-coined verb is introduced to avoid circumlocution, for this time only: therefore I hope your readers will excuse it. I conjugate it after the regular verb to revise — improvise — improvising — improvised. ["On the Improvvisatori of Italy," in The Athenaeum, August 1808]
Our travellers have introduced among us the substantive improvisatore unaltered from the Italian; but as the verb improvisare could not be received without alteration, we lack it altogether, though the usage of the noun requires that of the verb: I here endeavor to supply the deficience by the word improvisate. [Samuel Oliver Jr., "A General, Critical Grammar of the Inglish Language," London, 1825]
Old English bringan "to bear, convey, take along in coming; bring forth, produce, present, offer" (past tense brohte, past participle broht), from Proto-Germanic *brangjanan (source also of Old Frisian branga "attest, declare, assure," Middle Dutch brenghen, Old High German bringan, German bringen, Gothic briggan). There are no exact cognates outside Germanic, but it appears to be from PIE *bhrengk- (source also of Welsh he-brwng "bring"), which, according to Watkins, isbased on root *bher- (1) "to carry," also "to bear children," but Boutkan writes, "We are probably dealing with a Germanic/Celtic substratum word."
The tendency to conjugate this as a strong verb on the model of sing, drink, etc., is ancient: Old English also had a rare strong past participle form, brungen, corresponding to modern colloquial brung.
To bring about "effect, accomplish" is from late 14c. To bring down is from c. 1300 as "cause to fall," 1530s as "humiliate," 1590s as "to reduce, lessen." To bring down the house figuratively (1754) is to elicit applause so thunderous it collapses the theater roof. To bring forth "produce," as young or fruit is from c. 1200. To bring up is from late 14c. as "to rear, nurture;" 1875 as "introduce to consideration." To bring up the rear "move onward at the rear" is by 1708.
