borageyoudaoicibaDictYouDict
borage: [13] The plant-name borage comes via Old French bourrache from Latin borrāgo. Various words have been advanced as an ultimate source, including late Latin burra ‘shaggy cloth’, on account of its hairy leaves, but in view of the fact that the Arabs used the plant medicinally to induce sweating, the likeliest contender is Arabic abū ‘āraq, literally ‘father of sweat’.
borderyoudaoicibaDictYouDict
border: [14] English acquired border from Old French bordure. This came from the common Romance verb *bordāre ‘border’, which was based on *bordus ‘edge’, a word of Germanic origin whose source, *borthaz, was the same as that of English board in the sense ‘side of a ship’.
=> board
boreyoudaoicibaDictYouDict
bore: Bore ‘make a hole’ [OE] and bore ‘be tiresome’ [18] are almost certainly two distinct words. The former comes ultimately from an Indo-European base *bhor-, *bhr-, which produced Latin forāre ‘bore’ (whence English foramen ‘small anatomical opening’), Greek phárynx, and prehistoric Germanic *borōn, from which we get bore (and German gets bohren). Bore connoting ‘tiresomeness’ suddenly appears on the scene as a sort of buzzword of the 1760s, from no known source; the explanation most commonly offered for its origin is that it is a figurative application of bore in the sense ‘pierce someone with ennui’, but that is not terribly convincing.

In its early noun use it meant what we would now call a ‘fit of boredom’. There is one other, rather rare English word bore – meaning ‘tidal wave in an estuary or river’ [17]. It may have come from Old Norse bára ‘wave’.

bornyoudaoicibaDictYouDict
born: [OE] The Old English past participle of the verb meaning ‘bear’ was boren. By Middle English times this had become contracted to born(e), but no distinction in meaning was made on the basis of spelling. This did not come about until around 1600, since when born has become established as the obstetric orthography, while borne remains the straightforward past participle of bear ‘carry’.
=> bear
boroughyoudaoicibaDictYouDict
borough: [OE] Borough (Old English burg or burh) comes from Germanic *burgs ‘fortress’ (whence also German burg ‘castle, stronghold’). It was a derivative of the base *burg- ‘protect’ (whence also bury), a variant of *berg- (source of English barrow ‘mound’ and German berg ‘mountain’) and *borg- (source of English borrow).

At some time during the prehistoric Germanic period a progression in meaning began to take place from ‘fortress’ (which had largely died out in English by 1000), through ‘fortified town’, to simply ‘town’. Romance languages borrowed the word, giving for instance French bourg, from which English gets burgess [13] and bourgeois [16]. Burrow [13] is probably a variant form.

=> bourgeois, burgess, burrow, bury
borrowyoudaoicibaDictYouDict
borrow: [OE] Modern English borrow is a descendant of Old English borgian, which came from the Germanic base *borg-. This was a variant of *berg- (source of English barrow ‘mound’) and *burg- (source of English borough and bury). The underlying sense of the Germanic base was ‘protection, shelter’, and the development of meaning in the case of borrow seems to have been like this: originally, to borrow something from somebody was to receive it temporarily from them in return for some sort of security, which would be forfeited if the thing borrowed were not kept safe and eventually returned.

Gradually, the notion of giving some sort of concrete security, such as money, weakened into a spoken pledge, which by modern times had become simply the unspoken assumption that anything that has been borrowed must by definition be returned.

=> barrow, borough, bury

elaborateyoudaoicibaDictYouDict
elaborate: [16] Etymologically, something that is elaborate has been produced by hard work. The word comes from ēlabōrātus, the past participle of Latin ēlabōrāre; this was a compound verb formed from the prefix ex- ‘out’ and labor ‘work’ (source of English labour). The notion of ‘painstaking work’ had passed by the early 17th century into ‘extreme detail’.

aborigine (n.)youdaoicibaDictYouDict
1858, mistaken singular of aborigines (1540s; the correct singular is aboriginal), from Latin Aborigines "the first ancestors of the Romans; the first inhabitants" (especially of Latium), possibly a tribal name, or from or made to conform to ab origine, literally "from the beginning." Extended 1789 to natives of other countries which Europeans have colonized. Australian slang shortening Abo attested from 1922.
aborning (adv.)youdaoicibaDictYouDict
1893, American English, from a- (1) + born + -ing (2).
abort (v.)youdaoicibaDictYouDict
1570s, "to miscarry," from Latin abortus, past participle of aboriri "to miscarry" (see abortive); 1610s as "to deliberately terminate" anything, but especially a pregnancy, which seems to be the literal sense. Transitive meaning "to cause a woman to miscarry" is recorded from 1933. Related: Aborted; aborting.
abortifacient (n.)youdaoicibaDictYouDict
1875, noun and adjective, from Latin abortus (see abortive) + facientem "making," related to facere "to make, do" (see factitious). An earlier word for this in the noun sense was abortive (1640s).
abortion (n.)youdaoicibaDictYouDict
1540s, originally of both deliberate and unintended miscarriages; from Latin abortionem (nominative abortio) "miscarriage; abortion," noun of action from past participle stem of aboriri "to miscarry" (see abortive).

Earlier noun in English was simple abort (early 15c.) "miscarriage." In 19c. some effort was made to distinguish abortion "expulsion of the fetus between 6 weeks and 6 months" from miscarriage (the same within 6 weeks of conception) and premature labor (delivery after 6 months but before due time). The deliberate miscarriage was criminal abortion. This broke down late 19c. as abortion came to be used principally for intentional miscarriages, probably via phrases such as procure an abortion.

Foeticide (n.) appears 1823 as a forensic medical term for deliberate premature fatal expulsion of the fetus; also compare prolicide. Another 19c. medical term for it was embryoctony, from Latinized form of Greek kteinein "to destroy." Abortion was a taboo word for much of early 20c., disguised in print as criminal operation (U.S.) or illegal operation (U.K.), and replaced by miscarriage in film versions of novels.
abortionist (n.)youdaoicibaDictYouDict
1872, from abortion + -ist.
abortive (adj.)youdaoicibaDictYouDict
late 14c., "born prematurely or dead," from Latin abortivus "pertaining to miscarriage; causing abortion," from abort-, past participle stem of aboriri "disappear, miscarry," from ab- "amiss" (see ab-) + oriri "appear, be born, arise" (see orchestra); the compound word used in Latin for deaths, miscarriages, sunsets, etc. The Latin verb for "to produce an abortion" was abigo, literally "to drive away." Not originally used to imply forced or deliberate miscarriage; from 14c.-18c. stillborn children or domestic animals were said to be abortive. Also see abortion. Related: Abortiveness.
airborne (adj.)youdaoicibaDictYouDict
1640s, "carried through the air," from air (n.1) + borne. Of military units, from 1937.
arbor (n.)youdaoicibaDictYouDict
c. 1300, herber, "herb garden," from Old French erbier "field, meadow; kitchen garden," from Latin herba "grass, herb" (see herb). Later "a grassy plot" (early 14c., a sense also in Old French), "a shaded nook" (mid-14c.). Probably not from Latin arbor "tree," though perhaps influenced by its spelling.

The change from er- to ar- before consonants in Middle English also reflects a pronunciation shift: compare farm from ferme, harbor from Old English herebeorg.

belabor (v.)youdaoicibaDictYouDict

borage (n.)youdaoicibaDictYouDict
flowering plant used in salads, mid-13c., from Anglo-French, Old French borage (13c., Modern French bourrache), from Medieval Latin borrago.

The modern form is a result of the French word being borrowed by Italian then passed back to French with a suffix and re-borrowed into English in its current form by 1590s.
border (n.)youdaoicibaDictYouDict
mid-14c., from Old French bordure "seam, edge of a shield, border," from Frankish *bord or a similar Germanic source (compare Old English bord "side;" see board (n.2)).

The meaning "diameter of a tube" is first recorded 1570s; hence figurative slang full bore (1936) "at maximum speed," from notion of unchoked carburetor on an engine. Sense of "be tiresome or dull" first attested 1768, a vogue word c. 1780-81 according to Grose (1785); possibly a figurative extension of "to move forward slowly and persistently," as a boring tool does.
