Baltic nation, from Lithuanian Lietuva, a name of unknown origin, perhaps from a PIE source related to Latin litus "shore" (see littoral) and thus meaning "shoreland." Related: Lithuanian (c. 1600 as a noun). Kant, who was born in nearby Königsberg, was the first to call attention to its philological purity; it preserves many ancient Indo-European features, and "Lithuanian peasants can understand Sanskrit sentences pronounced by learned scholars" according to the "Encyclopedia Americana" (1919).
[T]he Lithuanian language is remarkable for its great beauty. It has more endearing terms than the Spanish, the Italian or the Russian. If the value of a nation in the whole of humanity were to be measured by the beauty and purity of its language, the Lithuanians would rank first among the nations of Europe. [Elisee Reclus, "Geographie Universelle," 1875]
masc. proper name, from Old French Rogier, from Old High German Hrotger, literally "famous with the spear," from hruod- "fame, glory" + ger "spear" (see gar (n.)). "The name was introduced from Norman where OG Rodger was reinforced by the cognate ON Hroðgeirr" [Dictionary of English Surnames]. Pet forms include Hodge and Dodge. As a generic name for "a person," attested from 1630s. In 16c.-17c. cant, "a goose." Slang meaning "penis" was popular c. 1650-c. 1870; hence the slang verb sense of "to copulate with (a woman)," which is attested from 1711.
The use of the word in radio communication to mean "yes, I understand" is attested from 1941, from the U.S. military phonetic alphabet word for the letter -R-, in this case an abbreviation for "received." It is said to have been used likewise by the R.A.F. since 1938. Roger de Coverley, once a favorite English country dance, is said to have been so called from 1685. Addison took him early 18c. as the name of a recurring character in the "Spectator."
THE first of our society is a gentleman of Worcestershire, of ancient descent, a baronet, his name Sir Roger de Coverley. His great-grandfather was inventor of that famous country-dance which is called after him. All who know that shire are very well acquainted with the parts and merits of Sir Roger. [Addison]
late 14c., of language, "German, non-Scandinavian continental Germanic," also as a noun, "a German language;" also in Duche-lond "Germany." By mid-15c. distinguished into Higher and Lower, and used after c. 1600 in the narrower sense "Hollanders, residents of the Netherlands." From Middle Dutch duutsch, from Old High German duitisc, from Proto-Germanic *theudō "popular, national" (source of Modern German Deutsch), from PIE *teuta- "tribe" (compare Teutonic).
It corresponds to the Old English adjective þeodisc "belonging to the people," which was used especially of the common language of Germanic people (as opposed to Latin), a derivative of the Old English noun þeod "people, race, nation." The language name is first attested in Latin as theodice (786 C.E.) in correspondence between Charlemagne's court and the Pope, in reference to a synodical conference in Mercia; thus it refers to Old English. Its first use in reference to a German language (as opposed to a Germanic one) is two years later. The sense was extended from the language to the people who spoke it (in German, Diutisklant, ancestor of Deutschland, was in use by 13c.).
The sense in of the adjective in English narrowed to "of the Netherlands" in 17c., after they became a united, independent state and the focus of English attention and rivalry. In Holland, Duits (formerly duitsch) is used of the people of Germany. The old use of Dutch for "German" continued in America (Irving and Cooper still distinguish High Dutch "German" and Low Dutch "Dutch") and survives in Pennsylvania Dutch for the descendants of religious sects that immigrated from the Rhineland and Switzerland and their language.
Since c. 1600, Dutch (adj.) has been a "pejorative label pinned by English speakers on almost anything they regard as inferior, irregular, or contrary to 'normal' (i.e., their own) practice" [Rawson]. E.g. ironical Dutch treat, of each person paying for himself (1887), Dutch courage "boldness inspired by intoxicating spirits" (1809), nautical Dutch talent "any piece of work not done in shipshape style (1867), etc. — probably exceeded in such usage only by Indian and Irish — reflecting first British commercial and military rivalry and later heavy German immigration to U.S.
Dutch concert, a concert in which each one sings his own song at the same time that his neighbor sings his; or a concert in which each one sings a verse of any song he pleases, some well-known chorus being sung after each verse. [Century Dictionary, 1897]
The Dutch themselves spoke English well enough to understand the unsavory connotations of the label and in 1934 Dutch officials were ordered by their government to stop using the term Dutch. Instead, they were to rewrite their sentences so as to employ the official The Netherlands. [Rawson]
Dutch oven is from 1769; OED lists it among the words describing things from Holland, but perhaps it is here used in the slighting sense. Dutch elm disease (1927) so called because it was first discovered in Holland (caused by fungus Ceratocystis ulmi). A Dutch uncle (1838) is one who is kindly severe and direct.
