Scandinavian country from Dane, the people's name, + Danish mark "border" (see mark (n.1)). The modern form is attested from late 14c. (from earlier Denemarke, c. 1200, from Old English Dene-mearce), but originally it meant western Scandinavia generally, "the lands of the Danes and Northmen." As an adjective, Middle English had Dene-marchish.
It forms all or part of: Cymric; demarcation; Denmark; emarginate; landmark; march (v.) "walk with regular tread;" march (n.2) "boundary;" marchioness; margin; margrave; mark (n.1) "trace, impression;" mark (n.2) "unit of money or weight;" marque; marquee; marquetry; marquis; remark; remarkable.
It is the hypothetical source of/evidence for its existence is provided by: Latin margo "margin;" Avestan mareza- "border;" Old Irish mruig, Irish bruig "borderland," Welsh bro "district;" Old English mearc "boundary, sign, limit, mark," Gothic marka "boundary, frontier."
"of or pertaining to Denmark or the Danes," 14c., replacing Old English Denisc "people of Denmark" (also including the Norse), with vowel change as in Dane (q.v.). As a noun, "the language of the Danes," from early 15c. Danish pastry is by 1934; shortened form danish is by 1963. It seems to have been invented in Vienna, but for some reason it was associated with Scandinavia. The Danes correctly call it Wienerbrod "Viennese bread." In reference to furniture styles, Danish modern is from 1948.
Scandinavian masc. proper name, popular with early kings, the first to use it was Magnus I, king of Norway and Denmark (d. 1047), who evidently took it in emulation of Charlemagne (Latin Carolus Magnus) under the impression that magnus (Latin, literally "great," from PIE root *meg- "great") was a personal name.
capital of Denmark, Danish København, literally "merchant's port," from Danish køber "merchant," literally "buyer" (see cheap (adj.)), + havn "port" (see haven). English picked up cope 15c.-17c. from Low German in the sense of "to buy, barter, make a bargain," but it has become obsolete.
"native or inhabitant of Denmark," early 14c. (in plural, Danes), from Danish Daner, (Medieval Latin Dani), which is perhaps ultimately from a source related to Old High German tanar "sand bank," in reference to their homeland, or from Proto-Germanic *den- "low ground," for the same reason.
It replaced Old English Dene (plural), which was used of Northmen generally. Shakespeare has Dansker "a Dane" (c. 1600). Dane was applied by 1774 to a breed of large dogs.
Danegeld (attested from 1086; it was first imposed in 991) supposedly originally was a tax to pay for protection from the Northmen (either to outfit defensive armies or to buy peace), continued under later kings for other purposes. Danelaw (c. 1050) was "the body of Danish law in force over that large part of England under Viking rule after Alfred's treaty in 878;" the application to the land itself is modern (1837, Danelagh).
