"quadruped of the genus Canis," Old English docga, a late, rare word, used in at least one Middle English source in reference specifically to a powerful breed of canine; other early Middle English uses tend to be depreciatory or abusive. Its origin remains one of the great mysteries of English etymology.ETD dog (n.).2

The word forced out Old English hund (the general Germanic and Indo-European word, from root from PIE root *kwon-) by 16c. and subsequently was picked up in many continental languages (French dogue (16c.), Danish dogge, German Dogge (16c.). The common Spanish word for "dog," perro, also is a mystery word of unknown origin, perhaps from Iberian. A group of Slavic "dog" words (Old Church Slavonic pisu, Polish pies, Serbo-Croatian pas) likewise is of unknown origin.ETD dog (n.).3

In reference to persons, by c. 1200 in abuse or contempt as "a mean, worthless fellow, currish, sneaking scoundrel." Playfully abusive sense of "rakish man," especially if young, "a sport, a gallant" is from 1610s. Slang meaning "ugly woman" is from 1930s; that of "sexually aggressive man" is from 1950s.ETD dog (n.).4

Many expressions — a dog's life (c. 1600), go to the dogs (1610s), dog-cheap (1520s), etc. — reflect the earlier hard use of the animals as hunting accessories, not pets. In ancient times, "the dog" was the worst throw in dice (attested in Greek, Latin, and Sanskrit, where the word for "the lucky player" was literally "the dog-killer"), which plausibly explains the Greek word for "danger," kindynos, which appears to be "play the dog" (but Beekes is against this).ETD dog (n.).5

Meaning "something poor or mediocre, a failure" is by 1936 in U.S. slang. From late 14c. as the name for a heavy metal clamp of some kind. Dog's age "a long time" is by 1836. Adjectival phrase dog-eat-dog "ruthlessly competitive" is by 1850s. Phrase put on the dog "get dressed up" (1934) may be from comparison of dog collars to the stiff stand-up shirt collars that in the 1890s were the height of male fashion (and were known as dog-collars from at least 1883).ETD dog (n.).6

dogberry (n.)

"the berry of the dogwood tree," 1550s; see dogwood + berry.ETD dogberry (n.).2

dog-collar (n.)

"collar made for a dog," 1520s, from dog (n.) + collar (n.).ETD dog-collar (n.).2

dog days (n.)

"period of dry, hot weather at the height of summer," 1530s, from Latin dies caniculares, the idea, though not the phrase, from Greek; so called because they occur around the time of the heliacal rising of Sirius, the Dog Star (kyōn seirios). Noted as the hottest and most unwholesome time of the year; often reckoned as July 3 to August 11, but variously calculated, depending on latitude and on whether the greater Dog-star (Sirius) or the lesser one (Procyon) is reckoned.ETD dog days (n.).2

The heliacal rising of Sirius has shifted down the calendar with the precession of the equinoxes; in ancient Egypt c. 3000 B.C.E. it coincided with the summer solstice, which also was the new year and the beginning of the inundation of the Nile. The "dog" association apparently began here (the star's hieroglyph was a dog), but the reasons for it are now obscure.ETD dog days (n.).3

doge (n.)

"chief magistrate of the old republics of Venice and Genoa," 1540s, from Venetian dialect doge, from Latin ducem, accusative of dux "leader" (from PIE root *deuk- "to lead"). Related: Dogate; dogeship.ETD doge (n.).2

dog-ear (v.)

also dogs-ear, "to use a book so as to leave the corners of the leaves soiled and curled over" (like the ears of a dog), 1650s. Dog's ear (n.) is by 1725. Dog-eared in the general or extended sense of "worn, unkempt" is by 1894.ETD dog-ear (v.).2

dogface (n.)

"soldier in the U.S. Army," especially an infantryman, by 1941, from dog (n.) + face (n.). Said to have been originally a contemptuous name given by the Marines.ETD dogface (n.).2

dogfight (n.)

also dog-fight, "aerial combat," World War I air forces slang, from earlier meaning "riotous brawl" (1880s); from dog (n.) + fight (n.). The literal sense of "a fight among or between dogs" is from 1650s (Middle English had dogg feghttyng, c. 1500).ETD dogfight (n.).2

dogfish (n.)

a name for various types of small shark, mid-15c., dogge fysch, from dog (n.) + fish (n.). It is said to be so called because it hunts in packs. The wild dog was the image of sharks in classical antiquity as well, and Greek used kyon "dog" also for dogfish and sharks, especially the smaller kind.ETD dogfish (n.).2

Greek galeos "dogfish or shark" perhaps is based on galen "weasel, marten," which also was a fish name.ETD dogfish (n.).3

dogger (n.)

"two-masted fishing boat," used in North Sea fishery, mid-14c., a word of unknown origin, perhaps from Dutch. It likely is the source of the name Dogger Bank (1660s) for the great banks of shoals in the North Sea that are drowned lands from the Ice Age. Related: Doggerman.ETD dogger (n.).2

doggerel (n.)

1630s, "Any rhyming verse in which the meter is forced into metronomic regularity by the stressing of normally unstressed syllables and in which rhyme is forced or banal" [Miller Williams, "Patterns of Poetry"]. Earlier as an adjective (rim doggerel, late 14c.), an epithet applied to loose, irregular verse in burlesque poetry.ETD doggerel (n.).2

Probably from pejorative suffix -rel + dog (n.), but the sense connection is not obvious. Perhaps it was applied to bad poetry with a suggestion of puppyish clumsiness, or being fit only for dogs, or from the "mean, contemptible" associations of dog in Middle English. Attested as a surname from late 13c., but the sense is not evident. Related: Doggerelist.ETD doggerel (n.).3

doggy (n.)

also doggie, "a little dog, a pet word for a dog," 1825, from dog (n.) + -y (3). Doggy-bag "bag provided by restaurants for customers to take home leftovers" (presumably to feed to the dog) is attested by 1962.ETD doggy (n.).2

As an adj. doggy is attested from late 14c., from -y (2). The word has been used in various formations at least since late 19c. to describe the rear-entry variant of the human sex act when one partner is on all fours.ETD doggy (n.).3

dog-gone (adj.)

also doggone, colloquial minced epithet, by 1849, Western American English, a "fantastic perversion of god-damned" [Weekley]. But Mencken favors the theory that it is "a blend form of dog on it; in fact it is still often used with it following. It is thus a brother to the old English phrase, 'a pox upon it,' but is considerably more decorous." Dog on it was the usual early spelling, so it was perhaps at least felt as such by those using it.ETD dog-gone (adj.).2

But there are many examples of similar words serving as euphemistic perversions of God: Compare dod for "God" in many oaths (late 17c. through 19c.); dodgasted (probably "God-blasted," in use late 19c., early 20c.); dod-rot (1842).ETD dog-gone (adj.).3

doghouse (n.)

also dog-house, "box in the shape of a house for use by dogs," 1610s, from dog (n.) + house (n.). Originally a kennel; application to the backyard type, for a single animal, is from late 19c. Figurative in the doghouse "in temporary disgrace" is by 1932.ETD doghouse (n.).2

dogie (n.)

"motherless calf in a herd," 1887, cowboy slang, of uncertain origin. It may have had an earlier, more specific meaning:ETD dogie (n.).2

dog-leg (adj.)

also dogleg, "bent like a dog's hind leg," 1843, earlier dog-legged (1703), which was used originally of a type of staircase which has no well hole and consists of two flights with or without winders. See dog (n.) + leg (n.).ETD dog-leg (adj.).2

dogma (n.)

"a settled opinion, a principle held as being firmly established," c. 1600 (in plural dogmata), from Latin dogma "philosophical tenet," from Greek dogma (genitive dogmatos) "opinion, tenet," literally "that which one thinks is true," from dokein "to seem good, think" (from PIE root *dek- "to take, accept"). Regarded in 17c.-18c. as a Greek word in English but subsequently nativized.ETD dogma (n.).2

dogmatic (adj.)

1680s, of persons, writings, etc., "disposed to make positive assertions without presenting arguments or evidence;" 1706, "pertaining to or of the nature of dogma," from Late Latin dogmaticus, from Greek dogmatikos "pertaining to doctrines," from dogma (genitive dogmatos) "opinion, tenet," literally "that which one thinks is true," from dokein "to seem good, think" (from PIE root *dek- "to take, accept"). Related: Dogmatical (c. 1600).ETD dogmatic (adj.).2

dogmatism (n.)

"character of being dogmatic; authoritative assertion of doctrines or opinions," c. 1600, but not in common use until 19c., from French dogmatisme (16c.), from Medieval Latin dogmatismus, from Latin dogma "philosophical tenet" (see dogma). Related: Dogmatist.ETD dogmatism (n.).2

do-gooder (n.)

"a person who actively seeks to correct social ills in an idealistic, but usually impractical or superficial, way," 1650s (as do-good), in "Zootomia, or Observations on the Present Manners of the English: Briefly Anatomizing the Living by the Dead. With An Usefull Detection of the Mountebanks of Both Sexes," written by Richard Whitlock, a medical doctor. Probably used even then with a taint of impractical idealism. The verbal phrase do good "do good deeds" was in Old English.ETD do-gooder (n.).2

Modern pejorative use seems to have begun on the socialist left, mocking those who were unwilling to take a hard line. OED has this citation, from The Nation in 1923:ETD do-gooder (n.).3

The form do-gooder appears in American English by 1922, presumably because do-good was no longer felt as sufficiently noun-like. A slightly older word for this was goo-goo.ETD do-gooder (n.).4

dog-paddle (n.)

"type of swimming stroke resembling a dog's swimming," 1860, from dog (n.) + paddle.ETD dog-paddle (n.).2

The trees have hard, white wood that was said to have been used in making butchers' skewers; another name for it was skewer-wood. This explanation is as old as the word itself in English, but the form *dagwood is not attested. Another guess is that the tree was given the name in reference to its fruit, which was called dogberry from 1550s, and dog (n.) had implications of "cheap, inferior" (i.e. "fit for a dog").ETD dogwood (n.).3

doily (n.)

"small, ornamental napkin," 1714, short for doily-napkin (1711), from doily "thin, woolen fabric;" supposedly from Doiley, surname of a noted late 17c.-early 18c. dry-goods dealer on London's Strand. Doily earlier meant "genteel, affordable woolens" (1670s), evidently from the same source. The surname is d'Ouilly, from one of several places called Ouilly in Normandy.ETD doily (n.).2

dolce vita (n.)

"life of pleasure," 1961, Italian, from the title of Fellini's 1960 film. The Italian elements are from Latin dulcis "sweet" (see dulcet) + Latin vita "life," from PIE root *gwei- "to live."ETD dolce vita (n.).2

doldrums (n.)

by 1803, "low spirits, the blues, the dumps," colloquial, probably from dulled, past participle of dull (v.) in the sense of "make (someone) slow-witted," with ending perhaps patterned on tantrum.ETD doldrums (n.).2

Transferred sense, in reference to sailing ships, "in a becalmed condition, unable to make headway" is by 1824. This was extended in nautical use to parts of the sea near the equator that abound in calms, squalls, and light, baffling winds (1848) and the weather characteristic of these parts. "Apparently due to a misunderstanding of the phrase 'in the doldrums', the state being taken as a locality" [OED].ETD doldrums (n.).3

doleful (adj.)

late 13c., with -ful, from Middle English dole "emotion of grief, sorrow, lamentation, mourning" (early 13c., now archaic), from Old French doel (Modern French deuil), from Late Latin dolus "grief," from Latin dolere "suffer, grieve," which is of uncertain origin. De Vaan explains it as from PIE *dolh-eie- "to split" (source also of Middle Welsh e-thyl "chooses"), a causative verb from root *delh- "to chop," "under the assumption than 'pain' was expressed by the feeling of 'being torn apart'." Related: Dolefully; dolefulness.ETD doleful (adj.).2

dole (v.)

mid-15c., dolen, "distribute, hand out (alms)," from dole (n.). Meaning "give in portions or small quantities" (as alms to the poor) is from 1749. Related: Doled; doling.ETD dole (v.).2

But Boutkan writes, "Most probably, we are dealing with a substratum word in Gmc."ETD dole (n.).2

Meaning "a part apportioned or divided out" is from late 12c.; that of "distribution of alms or gifts" is by late 13c. Specifically as "a portion of money, food, or other things distributed in charity" is by late 15c. From 1919 it became the popular name in Britain for various government payments made regularly to the unemployed. Hence on the dole (1920s).ETD dole (n.).3

dollar (n.)

"monetary unit or standard of value in the U.S. and Canada," 1550s, daler, originally in English the name of a large, silver coin of varying value in the German states, from Low German daler, from German taler (1530s, later thaler), abbreviation of Joachimstaler, literally "(gulden) of Joachimstal," coin minted 1519 from silver from mine opened 1516 near Sankt Joachimsthal, town in Erzgebirge Mountains in northwest Bohemia. German Tal is cognate with English dale. The spelling had been modified to dollar by 1600.ETD dollar (n.).2

The thaler was from 17c. the more-or-less standardized coin of northern Germany (as opposed to the southern gulden). It also served as a currency unit in Denmark and Sweden (and later was a unit of the German monetary union of 1857-73 equal to three marks).ETD dollar (n.).3

English colonists in America used the word dollar from 1580s in reference to Spanish peso or "piece of eight," also a large silver coin of about the same fineness as the thaler. Due to extensive trade with the Spanish Indies and the proximity of Spanish colonies along the Gulf Coast, the Spanish dollar probably was the coin most familiar in the American colonies and the closest thing to a standard in all of them.ETD dollar (n.).4

When the Revolution came, it had the added advantage of not being British. It was used in the government's records of public debt and expenditures, and the Continental Congress in 1786 adopted dollar as a unit when it set up the modern U.S. currency system, which was based on the suggestion of Gouverneur Morris (1782) as modified by Thomas Jefferson. None were circulated until 1794.ETD dollar (n.).5

Phrase dollars to doughnuts "an assured thing, a certainty" (such that one would bet a dollar against a doughnut on it) is attested by 1884; dollar diplomacy "financial imperialism, foreign policy based on financial and commercial interests" is from 1910.ETD dollar (n.).6

dollop (n.)

"a lump or glob," 1812, from earlier dallop "a patch, tuft or clump of grass" (1570s), an East Anglian dialect word of uncertain origin. As a verb, "serve out in large lumps," from 1825. Related: Dolloped; dolloping.ETD dollop (n.).2

dolmen (n.)

"structure consisting of one large, unhewn stone slab resting on two or more stones placed erect in the earth," such that a person may walk under it, 1859, from French dolmin applied 1796 by French general and antiquarian Théophile Malo Corret de La Tour d'Auvergne (1743-1800), perhaps from Cornish tolmen, literally "hole of stone," from Celtic men "stone."ETD dolmen (n.).2

Some suggest the first element may be Breton taol "table," a loan-word from Latin tabula "board, plank," but OED says the Breton form of this compound would be taolvean. "There is reason to think that this [tolmen] is the word inexactly reproduced by Latour d'Auvergne as dolmin, and misapplied by him and succeeding French archaeologists to the cromlech" [OED]. See cromlech, which is the same idea but arranged as one of a circle. Related: Dolmenic.ETD dolmen (n.).3

dolomite (n.)

Popularly applied to the dorado from late 16c. through some confusion. The constellation is so called from early 15c.ETD dolphin (n.).2

dolt (n.)

"dull, stupid fellow," 1540s, perhaps a variant of dold "dull, foolish" (mid-15c.), influenced by dulte, dolte, past-participle forms of Middle English dullen "to dull; make or become dazed or stupid" (see dull (v.)).

In the Middle Ages, German dom and Italian duomo were used for "cathedral" (on the notion of "God's house"), so English began to use this word in the sense "cupola," a dome at the intersection of the nave and the transept, or over the sanctuary, being a characteristic architectural feature of Italian cathedrals.ETD dome (n.).3

The word was used in U.S. also with reference to round summits of mountains, roofs of railroad cars, etc. The etymological sense "a building, a house," especially a stately one, was borrowed earlier in English (1510s) but mostly was restricted to poetry.ETD dome (n.).4
