blackmail [blackmail 词源字典]: blackmail: see mail
[blackmail etymology, blackmail origin, 英语词源]
bladder: bladder: [OE] Old English blǣdre came from a hypothetical West and North Germanic *blǣdrōn, a derivative of the stem *blǣ-, from which we get blow. The name perhaps comes from the bladder’s capacity for inflation. It was originally, and for a long time exclusively, applied to the urinary bladder.
=> blow
blade: blade: [OE] The primary sense of blade appears to be ‘leaf’ (as in ‘blades of grass’, and German blatt ‘leaf’). This points back to the ultimate source of the word, the Germanic stem *bhlō-, from which English also gets bloom, blossom, and the now archaic blow ‘come into flower’. However, the earliest sense recorded for Old English blæd was the metaphorical ‘flattened, leaflike part’, as of an oar, spade, etc. The specific application to the sharp, cutting part of a sword or knife developed in the 14th century.
=> bloom, blossom, blow
blame: blame: [12] Blame and blaspheme are ultimately the same word. Both come from Greek blasphēmein ‘say profane things about’, but whereas blaspheme has stuck to the path of ‘profanity’, blame has developed the more down-to-earth sense ‘reproach, censure’. The radical change of form seems to have come via blastēmāre, a demotic offshoot of late Latin blasphēmāre, which passed into Old French as blasmer, later blamer (whence English blame).
=> blaspheme
blanch: blanch: see blank
blancmange: blancmange: [14] Blancmange means literally simply ‘white food’. It comes from a French compound made up of blanc ‘white’ and manger, a noun derived from the verb manger ‘eat’ (related to English manger). Originally it was a savoury dish, of chicken or similar white meat in a sauce made with cream, eggs, rice, etc and often sugar and almonds. Gradually the meat content came to be omitted, and blancmange turned into a sweet dish, typically containing gelatine.
=> manger
blank: blank: [15] Although English got blank from French blanc ‘white’, its ultimate source is Germanic. Forms such as Old High German blanc ‘white’ suggest a prehistoric Germanic *blangkaz, which could have been borrowed into Romanic, the undifferentiated precursor of the Romance languages, as *blancus – hence French blanc, Italian bianco, Spanish blanco, and Portuguese branco.

The word originally meant simply ‘white’ in English, but this sense had all but died out by the early 18th century, by which time the present-day ‘unmarked’ was well established. Other derivatives of French blanc include the verb blanch [14], from French blanchier, and blanket [13], from Old French blancquet. Blanco is a trade name (based on blanc) coined in the 1890s for a whitening preparation for military webbing (subsequently applied to the khakicoloured version as well).
=> blanch, blanket
blaspheme: blaspheme: [14] Blaspheme has maintained a remarkable semantic and formal stability since its origins in Greek blásphēmos, which meant ‘speaking evil or profane things’ (blas- is related to blaptikós ‘hurtful’; the -phēmos element denotes ‘speaking’, and is related to phēmí ‘I say’). The derived Greek verb blasphēmein was transmitted via ecclesiastical Latin blasphēmāre to Old French and thence to English. Blastēmāre, an altered version of blasphēmāre, produced blame.
=> blame
blatant: blatant: [16] Blatant appears to have been coined, or at least introduced, by the poet Edmund Spenser. In the Faerie Queene 1596 he describes how ‘unto themselves they [Envy and Detraction] gotten had a monster which the blatant beast men call, a dreadful fiend of gods and men ydrad [dreaded]’. This ‘blatant beast’ was an allegorical representation of calumny. In the 17th century the word came to be applied to offensively voluble people, but the main modern sense, ‘offensively conspicuous’, does not seem to have developed until the late 19th century.

If the word was Spenser’s own introduction, it is not clear where he got it from. The likeliest candidate seems to be Latin blatīre ‘babble, gossip’, of imitative origin.
blaze: blaze: There are three distinct words blaze in English. The commonest, meaning ‘fire, flame’ [OE], comes from a prehistoric Germanic *blasōn. Its original signification was ‘torch’ (in the sense, of course, of a burning piece of wood or bunch of sticks), but by the year 1000 the main current meaning was established. The precise source of blaze ‘light-coloured mark or spot’ [17] is not known for certain, but there are several cognate forms in other Germanic languages, including Old Norse blesi and German blässe; perhaps the likeliest candidate as far as blaze is concerned is Middle Low German bles.

The verbal usage, as in ‘blaze a trail’ (that is, by making conspicuous marks on trees) originated in the mid 18th century. The related German adjective blass ‘pale’, which originally meant ‘shining’, points up the fact that ultimately these two words blaze are related, the primeval sense ‘shining’ having diverged on the one hand through ‘pale’, on the other through ‘glowing, burning’.

The third blaze, ‘proclaim’ [14], as in ‘blaze abroad’, is now seldom encountered. It originally meant ‘blow a trumpet’, and comes ultimately from the Indo-European base *bhlā- (source of blow). Its immediate source in English was Middle Dutch blāsen. Despite its formal and semantic similarity, it does not appear to have any connection with blazon [13], which comes from Old French blason ‘shield’, a word of unknown origin.

A blazer [19] got its name from being a brightly coloured jacket (from blaze meaning ‘fire, flame’). It originated among English university students in the late 19th century. According to a correspondent in the Daily News 22 August 1889, the word was originally applied specifically to the red jackets worn by members of the ‘Lady Margaret, St John’s College, Cambridge, Boat Club’.

But by the 1880s its more general application had become widely established: in the Durham University Journal of 21 February 1885 we read that ‘the latest novelty … for the river is flannels, a blazer, and spats’.
=> blow
bleak: bleak: [16] Bleak originally meant ‘pale’, and comes ultimately from an Indo-European base *bhleg-, possible source of black and a variant of *phleg-, which produced Greek phlégein ‘burn’ and Latin flagrāre ‘burn’ (whence English conflagration and flagrant; flame, fulminate, and refulgent are also closely related).

From *bhlegcame the prehistoric Germanic adjective *blaikos ‘white’, from which Old English got blāc ‘pale’ (the sense relationship, as with the possibly related blaze, is between ‘burning’, ‘shining brightly’, ‘white’, and ‘pale’). This survived until the 15th century in southern English dialects as bloke, and until the 16th century in the North as blake.

Its disappearance was no doubt hastened by its resemblance to black, both formally and semantically, since both ‘pale’ and ‘dark’ carry implications of colourlessness. Blake did however persist in Northern dialects until modern times in the sense ‘yellow’. Meanwhile, around the middle of the 16th century bleak had begun to put in an appearance, borrowed from a close relative of bloke/blake, Old Norse bleikr ‘shining, white’.

The modern sense ‘bare’ is recorded from very early on. A derivative of the Germanic base *blaikwas the verb *blaikjōn, source of Old English blǣcan ‘whiten’, the ancestor of modern English bleach (which may be related to blight). And a nasalized version of the stem may have produced blink [14].
=> bleach, blight, blink, conflagration, flagrant, flame, fulminate
bleed: bleed: [OE] As its form suggests, bleed is a derivative of blood, but a very ancient one. From Germanic *blōtham ‘blood’ was formed the verb *blōthjan ‘emit blood’, which came into Old English as blēdan, ancestor of bleed.
=> blood
blend: blend: [13] Old English had a verb blendan, but it meant ‘make blind’ or ‘dazzle’. Modern English blend appears to come from blend-, the present stem of Old Norse blanda ‘mix’ (a relative of Old English blandan ‘mix’). The ultimate source of this is not clear, but it does not seem to be restricted to Germanic (Lithuanian has the adjective blandus ‘thick’ in relation to soup), so it may not be too far-fetched to suggest a link with blind, whose Indo-European ancestor *bhlendhos meant among other things ‘confused’.
bless: bless: [OE] Bless occurs in no other language than English, and originally meant ‘mark with blood’, from some sort of religious rite in which such marking conferred sanctity. It probably goes back to a prehistoric Germanic formation *blōthisōjan, a derivative of *blōtham ‘blood’, which was taken up by no Germanic language other than Old English. Here it produced blētsian, which by the 13th century had become blesse. The word’s connotations of ‘happiness’ and ‘well-being’, which go back at least to the year 1000, were probably influenced by the etymologically unrelated bliss.
=> blood
blight: blight: [17] Blight appeared out of the blue in the early 17th century in agricultural and horticultural texts, and its origins are far from clear. It has, however, been speculated that it may be connected with the Old English words blǣce and blǣcthu, both terms for some sort of itchy skin condition such as scabies. These in turn are probably related to Old English blǣcan ‘bleach’, the link being the flaky whiteness of the infected skin.

In Middle English, blǣcthu would have become *bleht, which could plausibly have been the source of blight. A related piece in the jigsaw is blichening ‘blight or rust in corn’, found once in Middle English, which may have come ultimately from Old Norse blikna ‘become pale’.
=> bleach
blighty: blighty: [20] Blighty is a legacy of British rule in India. Originally a term used by British soldiers serving in India for ‘home, Britain’, it is an anglicization of Hindi bilāyatī, which meant ‘foreign’, and particularly ‘European’. This was actually a borrowing from Arabic wilāyat ‘district, country’, which was independently acquired by English in the 19th century in its Turkish form vilayet. It was a derivative of the Arabic verb waliya ‘rule’, and is related to walī ‘ruler’.
blimp: blimp: [20] The original blimp was a sort of small non-rigid military airship used in World War I. Its name is said to have come from its official designation as ‘type B (limp)’ (as opposed to ‘type A (rigid)’). Its rotund flaccidity suggested it in 1934 to the cartoonist David Low (1891– 1963) as a name for a character he had invented, a fat pompous ex-army officer (in full, Colonel Blimp) who was always cholerically airing reactionary views. The British public evidently recognized the character as an all too common type, and his name became a generic one, to the extent of inspiring spin-offs such as blimpish.
blind: blind: [OE] The connotations of the ultimate ancestor of blind, Indo-European *bhlendhos, seem to have been not so much ‘sightlessness’ as ‘confusion’ and ‘obscurity’. The notion of someone wandering around in actual or mental darkness, not knowing where to go, naturally progressed to the ‘inability to see’. Related words that fit this pattern are blunder, possibly from Old Norse blunda ‘shut one’s eyes’, blunt, and maybe also blend.

By the time the word entered Old English, as blind, it already meant ‘sightless’, but ancestral associations of darkness and obscurity were retained (Pepys in his diary, for instance, writes of a ‘little blind [that is, dark] bed-chamber’ 1666), and traces of them remain in such usages as ‘blind entrance’.
=> blend, blunder, blunt
blindfold: blindfold: [16] The original term for covering someone’s eyes with a bandage was blindfell [OE], which survived until the 16th century. This meant literally ‘strike someone blind’, the second element being the fell of ‘felling trees’. It appears that its past form, blindfelled, came to be mistaken for a present form, and this, together with some perceived connection with fold (presumably the ‘folding’ of the bandage round somebody’s head), conspired to produce the new verb blindfold.
bliss: bliss: [OE] Despite its formal and semantic similarity, bliss has no connection with bless. It comes ultimately from Germanic *blīthiz ‘gentle, kind’, which is the source of English blithe ‘happy’ [OE]. The addition of the noun suffix *-tjō produced the derivative *blīthsjō, which entered Old English as blīths ‘happiness’, later reduced to bliss.
=> blithe
