"deep sense of injury, the excitement of passion which proceeds from a sense of wrong offered to one's self or one's kindred or friends," especially when directed at the author of the affront, 1610s, from French ressentiment (16c.), verbal noun from ressentir (see resent). Slightly earlier in English in the French form resentiment (1590s); also compare ressentiment.
"Ridicule often parries resentment, but resentment never yet parried ridicule." [Walter Savage Landor, "Imaginary Conversations"]
"of excitement that presages death," from Old English fæge "doomed to die, fated, destined," also "timid, feeble;" and/or from Old Norse feigr, both from Proto-Germanic *faigjo- (source also of Old Saxon fegi, Old Frisian fai, Middle Dutch vege, Middle High German veige "doomed," also "timid," German feige "cowardly"), from the same source as foe. Preserved in Scottish. Sense of "displaying unearthly qualities" and "disordered in the mind (like one about to die)" led to modern ironic sense of "affected."
mid-15c., distraccioun, "the drawing away of the mind from one point or course to another or others," from Latin distractionem (nominative distractio) "a pulling apart, separating," noun of action from past-participle stem of distrahere "draw in different directions" (see distract).
Sense of "a drawing of the mind in different directions, mental confusion or bewilderment" is from 1590s. Meaning "violent mental disturbance, excitement simulating madness" (in driven to distraction, etc.) is from c. 1600. Meaning "a thing or fact that causes mental diversion or bewilderment" is from 1610s.
"government by the rabble," 1580s, from French ochlocratie (1560s), from Greek okhlokratia (Polybius) "mob rule," the lowest grade of democracy, from kratos "rule, power, strength" (see -cracy) + okhlos "(orderless) crowd, multitude, throng; disturbance, annoyance," which is probably literally "moving mass," from PIE *wogh-lo-, suffixed form of root *wegh- "to go, move." "Several possibilities exist for the semantic development: e.g. an agent noun *'driving, carrying, moving', or an instrument noun *'driver, carrier, mover'. ... An original meaning 'drive' could easily develop into both 'stirred mass, mob' and 'spiritual excitement, unrest'" [Beekes]. For sense development, compare mob (n.). Related: Ochlocrat, ochlocratic; ochlocratical. Greek also had okhlagogos "mob-leader, ochlagogue."
late 14c., twiteren, in reference to birds, of imitative origin (compare Old High German zwizziron, German zwitschern, Danish kvidre, Old Swedish kvitra). The noun meaning "condition of tremulous excitement" is attested from 1670s. The microblogging service with the 140-character limit was introduced in 2006. The following is considered an unrelated word of obscure origin:
TWITTER. 1. "That part of a thread that is spun too small." Yarn is said to be twined to twitters, when twined too small, S. Hence, to twitter yarn, to spin it unequally, A. Bor. Ray.
2. It is transferred to any person or thing that is slender or feeble. It is said of a lank delicate girl: "She is a mere twitter," S. [Jamieson, "Etymological Dictionary of the Scottish Language," Edinburgh, 1808]
