"a native of Germany," 1520s, from Latin Germanus (adjective and noun, plural Germani), first attested in writings of Julius Caesar, who used Germani to designate a group of tribes in northeastern Gaul, of unknown origin. Probably originally the name of an individual tribe, but Gaulish (Celtic) origins have been proposed, from words perhaps originally meaning "noisy" (compare Old Irish garim "to shout") or "neighbor" (compare Old Irish gair "neighbor"). Middle English had Germayns (plural, late 14c.), but only in the sense "ancient Teuton, member of the Germanic tribes." The earlier English word was Almain (early 14c.; see Alemanni) or Dutch.
Þe empere passede from þe Grees to þe Frenschemen and to þe Germans, þat beeþ Almayns. [John of Trevisa, translation of Higdon's Polychronicon, 1387]
Their name for themselves, die Deutschen (see Dutch), dates from 12c. Roman writers also used Teutoni as a German tribal name, and writers in Latin after about 875 commonly refer to the German language as teutonicus (see Teutonic). Meaning "the German language" in English is from 1748. High German (1823 in English) and Low German as a division of dialects is geographical: High German (from 16c. established as the literary language) was the German spoken in the upland regions in southern Germany, Low German (often including Dutch, Frisian, Flemish), also called Plattdeutsch was spoken in the regions near the North Sea. In the U.S. German also was used of descendants of settlers from Germany.
