drag (v.)youdaoicibaDictYouDict[drag 词源字典]
mid-15c., from Old Norse draga, or a dialectal variant of Old English dragan "to draw," both from Proto-Germanic *dragan "to draw, pull," from PIE root *dhragh- "to draw, drag on the ground" (cognates: Sanskrit dhrajati "pulls, slides in," Russian drogi "wagon;" but not considered to be directly the source of Latin trahere).

Meaning "to take a puff" (of a cigarette, etc.) is from 1914. Related: Dragged; dragging. Drag-out "violent fight" is from c. 1859. To drag (one's) feet (1946, in figurative sense) supposedly is from logging, from a lazy way to use a two-man saw.[drag etymology, drag origin, 英语词源]
drag (n.)youdaoicibaDictYouDict
c. 1300, "dragnet," perhaps from a Scandinavian source (compare Swedish dragg "grapnel") or from Old English dræge "dragnet," related to dragan "to draw" (see drag (v.)).

Sense of "annoying, boring person or thing" is 1813, perhaps from the notion of something that must be dragged as an impediment. Sense of "women's clothing worn by a man" is said to be 1870 theater slang, from the sensation of long skirts trailing on the floor (another guess is Yiddish trogn "to wear," from German tragen); drag queen is from 1941.

Drag racing (1947), is said to be from thieves' slang drag "automobile" (1935), perhaps ultimately from slang sense of "wagon, buggy" (1755), because a horse would drag it. By 1851 this was transferred to "street," as in the phrase main drag (which some propose as the source of the racing sense).
In addition to the time trials there are a number of "drag races" between two or more cars. They are run, not for record, but to satisfy the desire of most Americans to see who can get from here to there in the fastest time. ["Popular Mechanics," January 1947]
draughts (n.)youdaoicibaDictYouDict
British name for the tabletop game that in U.S. is checkers, c. 1400, from draught, perhaps because the pieces are "dragged" over the board in moves. Earlier it is recorded as jeu de dames (late 14c.).
dray (n.)youdaoicibaDictYouDict
mid-14c., Middle English noun derivative of Old English dragan "to draw," originally meaning a cart without wheels that has to be "dragged" (compare Old Norse draga "timber dragged behind a horse"); see drag (v.).
rehearse (v.)youdaoicibaDictYouDict
c. 1300, "to give an account of," from Anglo-French rehearser, Old French rehercier (12c.) "to go over again, repeat," literally "to rake over, turn over" (soil, ground), from re- "again" (see re-) + hercier "to drag, trail (on the ground), be dragged along the ground; rake, harrow (land); rip, tear, wound; repeat, rehearse;" from herse "a harrow" (see hearse (n.)). Meaning "to say over again, repeat what has already been said or written" is from mid-14c. in English; sense of "practice a play, part, etc." is from 1570s. Related: Rehearsed; rehearsing.
sled (n.)youdaoicibaDictYouDict
early 14c., "a dragged vehicle used for transport of heavy goods," from Middle Dutch sledde "sled," from Proto-Germanic *slid- (cognates: Old Saxon slido, Old Norse sleði, Danish slæde, Swedish släde, Old High German slito, German Schlitten "sledge"), from the same root as Old English slidan (see slide (v.)). Not found in Old English. In reference to a sleigh used for travel or recreation, it is attested from 1580s, now mainly American English.
suicide (n.)youdaoicibaDictYouDict
"deliberate killing of oneself," 1650s, from Modern Latin suicidium "suicide," from Latin sui "of oneself" (genitive of se "self"), from PIE *s(u)w-o- "one's own," from root *s(w)e- (see idiom) + -cidium "a killing" (see -cide). Probably an English coinage; much maligned by Latin purists because it "may as well seem to participate of sus, a sow, as of the pronoun sui" [Phillips]. The meaning "person who kills himself deliberately" is from 1728. In Anglo-Latin, the term for "one who commits suicide" was felo-de-se, literally "one guilty concerning himself."
Even in 1749, in the full blaze of the philosophic movement, we find a suicide named Portier dragged through the streets of Paris with his face to the ground, hung from a gallows by his feet, and then thrown into the sewers; and the laws were not abrogated till the Revolution, which, having founded so many other forms of freedom, accorded the liberty of death. [W.E.H. Lecky, "History of European Morals," 1869]
In England, suicides were legally criminal if of age and sane, but not if judged to have been mentally deranged. The criminal ones were mutilated by stake and given degrading burial in highways until 1823. Suicide blonde (one who has "dyed by her own hand") first attested 1921. Baseball suicide squeeze is attested from 1937.
