"lands of the American Midwest lying from roughly to the 104th meridian to the eastern slopes of the Rockies," 1755 (in singular form from 1680s), see plain (n.). Plains Indian is attested from 1844.
This region has a gradual slope from the mountains to the Missouri and Mississippi rivers, but is nowhere broken by any conspicuous ranges of hills. It is a region of small precipitation, wooded only along the banks of the streams, and not always there. The Plains and the prairies are not properly the same, from either a geographical or a climatological point of view. [Century Dictionary]
level or gently sloping ground between low hills with a stream flowing through it, Old English dæl "vale, valley, gorge," from Proto-Germanic *dalaz "valley" (source also of Old Saxon, Dutch, Gothic dal, Old Norse dalr, Old High German tal, German Tal "valley"), perhaps from PIE *dhel- "a hollow" (source also of Old Church Slavonic dolu "pit," Russian dolu "valley"), or perhaps a substratum word. It was preserved by Norse influence in the north of England. Related: Dalesman.
early 13c., palais, "official residence of an emperor, king, queen, archbishop, etc.," from Old French palais "palace, court" and directly from Medieval Latin palacium "a palace" (source of Spanish palacio, Italian palazzo), from Latin palatium "the Palatine hill," in plural, "a palace," from Mons Palatinus "the Palatine Hill," one of the seven hills of ancient Rome, where Augustus Caesar's house stood (the original "palace"), later the site of the splendid residence built by Nero. In English, the general sense of "magnificent, stately, or splendid dwelling place" is by c. 1300.
The hill name perhaps is ultimately from palus "stake" (see pale (n.)) on the notion of "enclosure." Another guess is that it is from Etruscan and connected with Pales, the supposed name of an Italic goddess of shepherds and cattle. De Vaan connects it with palatum "roof of the mouth; dome, vault," and writes, "Since the 'palate' can be referred to as a 'flattened' or 'vaulted' part, and since hills are also often referred to as 'flat' or 'vaulted' (if their form so suggests), a derivation of Palatium from palatum is quite conceivable."
French palais is the source of German Palast, Swedish palats and some other Germanic forms. Others, such as Old English palant, Middle High German phalanze (modern German Pfalz) are from the Medieval Latin word.
mid-15c., "fortified place, stronghold," from Old French fort "fort, fortress; strong man," noun use of adjective meaning "strong, stout, sturdy; hard, severe, difficult; hard to understand; dreadful, terrible; fortified" (10c.), from Latin fortis "strong, mighty; firm, steadfast; brave, spirited," from Old Latin forctus, which is of unknown etymology. Possibly from PIE root *bhergh- (2) "high, elevated," with derivatives referring to hills and hill-forts, or possibly from *dher- "to hold firmly, support." Figurative use of hold the fort attested from 1590s.
It forms all or part of: barrow (n.2) "mound, hill, grave-mound;" belfry; borough; bourgeoisie; burg; burgess; burgher; burglar; faubourg; iceberg.
It is the hypothetical source of/evidence for its existence is provided by: Sanskrit b'rhant "high," brmhati "strengthens, elevates;" Avestan brzant- "high," Old Persian bard- "be high;" Greek Pergamos, name of the citadel of Troy; Old Church Slavonic bregu "mountain, height;" Old Irish brigh "mountain;" Welsh bera "stack, pyramid."
1774, "glacier humped like a hill;" 1820 as "detached piece of a glacier or ice pack at sea," partial loan-translation of Dutch ijsberg, literally "ice mountain," from ijs "ice" (see ice (n.)) + berg "mountain" (from PIE root *bhergh- (2) "high," with derivatives referring to hills and hill-forts.). Similar formation in Norwegian isberg, Danish isbjerg.
Earlier English terms were sea-hill (1690s), island of ice (1610s). Phrase tip of the iceberg in a figurative sense (in allusion to most of it being unseen underwater) first recorded 1962. Iceberg lettuce attested from 1893, apparently originally a trade name.
1795 as "science of the past and present condition of the Earth's crust," from Modern Latin geologia "the study of the earth," from geo- "earth" + logia (see -logy). German Geologie is attested by 1785. In Medieval Latin, geologia (14c.) meant "study of earthly things," i.e. law, as distinguished from arts and sciences, which concern the works of God. Darwin used geologize as a verb.
There rolls the deep where grew the tree.
O earth, what changes hast thou seen!
There where the long street roars, hath been
The stillness of the central sea.
The hills are shadows, and they flow
From form to form, and nothing stands;
They melt like mist, the solid lands,
Like clouds they shape themselves and go.
[from "In Memoriam," 1850]
Old English bosm "breast; womb; surface; ship's hold," from West Germanic *bōsmaz (source also of Old Frisian bosm, Old Saxon bosom, Middle Dutch boesem, Dutch boezem, Old High German buosam, German Busen "bosom, breast"), perhaps from PIE root *bhou- "to grow, swell," or *bhaghus "arm" (in which case the primary notion would be "enclosure formed by the breast and the arms"), or possibly a word from a substrate language.
Bosoms in the narrowed or euphemistic meaning "a woman's breasts" is from 1959; bosomy "big-breasted" is from 1928 (earlier of rolling hills, etc.). Bosom-friend is attested 1580s; bosom buddy from 1924. Abraham's bosom "the abode of the blessed" is from Luke xvi.19-31.
c. 1400, "wooden siege tower on wheels" (late 13c. in Anglo-Latin with a sense "bell tower"), from Old North French berfroi "movable siege tower" (Modern French beffroi), from Middle High German bercfrit "protecting shelter," from Proto-Germanic compound *berg-frithu, literally "high place of security," or that which watches over peace." From bergen "to protect" (from PIE root *bhergh- (1) "to hide, protect") or [Watkins] *bergaz "mountain, high place" (from PIE root *bhergh- (2) "high," with derivatives referring to hills and hill-forts) + *frithu- "peace; personal security" (see affray).
The etymological meaning was forgotten, which led to folk-etymologies and a great diversity of spellings. It came to be used for bell towers (mid-15c.), which at first often were detached from church buildings (as the "Leaning Tower" of Pisa and the Campanile on Plaza San Marco in Venice), and the spelling was altered by dissimilation or by association with bell (n.).
"principal street of a (U.S.) town," 1810, from main (adj.) + street. Used allusively to indicate "mediocrity, small-town materialism" from late 19c., a sense reinforced by the publication of Sinclair Lewis's novel "Main Street" (1920).
But a village in a country which is taking pains to become altogether standardized and pure, which aspires to succeed Victorian England as the chief mediocrity of the world, is no longer merely provincial, no longer downy and restful in its leaf-shadowed ignorance. It is a force seeking to dominate the earth, to drain the hills and sea of color, to set Dante at boosting Gopher Prairie, and to dress the high gods in Klassy Kollege Klothes. Sure of itself, it bullies other civilizations, as a traveling salesman in a brown derby conquers the wisdom of China and tacks advertisements of cigarettes over arches for centuries dedicate to the sayings of Confucius.
