alphabetyoudaoicibaDictYouDict[alphabet 词源字典]
alphabet: [15] This word is based on the names of the first two letters of the Greek alphabet, alpha and beta, standing for the whole. It derives from Greek alphabētos, via Latin alphabētum. When it first came into English, purists tried to insist that it should be reserved for the Greek alphabet, and that the English alphabet should be referred to by the term ABC (which had been lexicalized in various forms, such as abece, apece, and absee, since the late 13th century), but, like most such prescriptive demands, this was a waste of breath and ink.

AlsatianyoudaoicibaDictYouDict
Alsatian: [17] Alsatian has been around since at least the late 17th century (although in early use it generally denoted not the Franco-German border province of Alsace but a no-go area in London, near the banks of the Thames, where criminals, vagabonds and prostitutes hung out, which was nicknamed ‘Alsatia’ because of the real Alsace’s reputation as a harbour for the disaffected).

It really came into its own, however, during World War I. A breed of dog known as the ‘German sheepdog’ or ‘German shepherd dog’ (German deutscher Schäferhund) had been introduced into Britain, but understandably, between 1914 and 1918 its stock fell considerably. When it was reintroduced after the war it was thought politic to give it a less inflammatory name, so it became officially the ‘Alsatian wolf-dog’ (even though it has nothing to do with Alsace, and there is no element of wolf in its genetic make-up).

It continued to be called the German shepherd in the USA, and in the latter part of the 20th century that usage crept back into Britain.

alsoyoudaoicibaDictYouDict
also: [OE] Also was a late Old English compound formed from all ‘exactly, even’ and swa ‘so’; it meant ‘in just this way, thus’, and hence (recalling the meaning of German also ‘therefore’) ‘similarly’. These two uses died out in, respectively, the 15th and 17th centuries, but already by the 13th century ‘similarly’ was developing into the current sense ‘in addition’. As came from also in the 12th century. In Old English, the notion of ‘in addition’ now expressed by also was verbalized as eke.

altaryoudaoicibaDictYouDict
altar: [OE] The etymological notion underlying the word altar is that of sacrificial burning. Latin altar, which was borrowed directly into Old English, was a derivative of the plural noun altāria, ‘burnt offerings’, which probably came from the verb adolēre ‘burn up’. Adolēre in turn appears to be a derivative of olēre ‘smell’ (the connection being the smell made by combustion), which is related to English odour, olfactory, and redolent. (The traditional view that altar derives from Latin altus ‘high’ is no longer generally accepted, although no doubt it played a part, by association, in its development.) In Middle English, the Old French form auter replaced altar, but in the 16th century the Latin form re-established itself.
=> odour, olfactory, redolent
alteryoudaoicibaDictYouDict
alter: [14] Alter comes from the Latin word for ‘other (of two)’, alter. In late Latin a verb was derived from this, alterāre, which English acquired via French altérer. Latin alter (which also gave French autre and English alternate [16], alternative [17], altercation [14], and altruism, not to mention alter ego) was formed from the root *al- (source of Latin alius – from which English gets alien, alias, and alibi – Greek allos ‘other’, and English else) and the comparative suffix *-tero-, which occurs also in English other.

Hence the underlying meaning of Latin alter (and, incidentally, of English other) is ‘more other’, with the implication of alternation between the two.

altruismyoudaoicibaDictYouDict
altruism: [19] Etymologically as well as semantically, altruism contains the notion of ‘other people’. It was borrowed from French altruisme, which was apparently coined in 1830 by the philosopher Auguste Comte on the basis of Italian altrui ‘that which belongs to other people’. This was the oblique case of altro ‘other’, from Latin alter. Littré’s Dictionnaire de la langue française suggests that the coinage was based on such French legal phrases as le bien d’autrui ‘the welfare of others’ and le droit d’autrui ‘the rights of others’ (autrui corresponds to Italian altrui).

aluminiumyoudaoicibaDictYouDict
aluminium: [19] Aluminium comes from a coinage by the English chemist Sir Humphry Davy, who discovered the metal. His first suggestion was alumium, which he put forward in Volume 98 of the Transactions of the Royal Society 1808: ‘Had I been so fortunate as … to have procured the metallic substances I was in search of, I should have proposed for them the names of silicium, alumium, zirconium, and glucium’.

He based it on Latin alūmen ‘alum’ (alum is a sulphate of aluminium, and the word alum, a 14th-century borrowing from French, derives ultimately from alūmen; alumina is an oxide of aluminium, and the word alumina is a modern Latin formation based on alūmen, which entered English at the end of the 18th century); and alūmen may be linked with Latin alūta ‘skins dried for making leather, using alum’.

Davy soon changed his mind, however, and in 1812 put forward the term aluminum – which remains the word used in American English to this day. British English, though, has preferred the form aluminium, which was mooted contemporaneously with aluminum on grounds of classical ‘correctness’: ‘Aluminium, for so we shall take the liberty of writing the word, in preference to aluminum, which has a less classical sound’, Quarterly Review 1812.

alwaysyoudaoicibaDictYouDict
always: [13] In Old English, the expression was alne weg, literally ‘all the way’. It seems likely that this was used originally in the physical sense of ‘covering the complete distance’, but by the time it starts to appear in texts (King Alfred’s is the first recorded use, in his translation of Boethius’s De consolatione philosophiae around 888) it already meant ‘perpetually’. Alway survived into modern English, albeit as an archaism, but began to be replaced as the main form by always in the 12th century.

The final -s is genitive, not plural, and was originally added to all as well as way: alles weis. It has a generalizing force, much as in modern English one might say of a morning for ‘every morning’.

=> way
AlzheimeryoudaoicibaDictYouDict
Alzheimer: Alzheimer’s disease [20] This serious brain disorder was first described in a scientific journal in 1912, and was given its name in honour of the German neurologist Alois Alzheimer (1864–1915). For many decades the term was largely confined to specialist medical journals, but in the 1970s, as the disease became better known, it seeped into the public domain.

amalgamateyoudaoicibaDictYouDict
amalgamate: [17] Amalgamate is a derivative of amalgam, a term for an alloy of mercury and another metal (now usually used for tooth fillings) borrowed into English from French or medieval Latin in the 15th century. Latin (amalagama) probably acquired the word from the Greek adjective málagma ‘softening’, a derivative of the verb malássein ‘soften’, which is a distant relative of English malleable (see MALLET).

amateuryoudaoicibaDictYouDict
amateur: [18] Etymologically, an amateur is simply a ‘lover’. That is what its ultimate Latin ancestor amator meant, and indeed in English it still denoted ‘someone who loves or is fond of something’ until well into the 19th century (‘am no amateur of these melons’, Mrs Atkinson, Tartar Steppes 1863). However, its immediate source, French amateur, had already evolved the subsidiary sense ‘one who does something solely for the enjoyment, not for payment’, and that is now its only English meaning.
amazeyoudaoicibaDictYouDict
amaze: [OE] Old English āmasian meant ‘stupefy’ or ‘stun’, with perhaps some reminiscences of an original sense ‘stun by hitting on the head’ still adhering to it. Some apparently related forms in Scandinavian languages, such as Swedish masa ‘be sluggish’ and Norwegian dialect masast ‘become unconscious’, suggest that it may originally have been borrowed from Old Norse.

The modern sense ‘astonish’ did not develop until the end of the 16th century; Shakespeare was one of its earliest exponents: ‘Crystal eyes, whose full perfection all the world amazes’, Venus and Adonis 1592. By the end of the 13th century both the verb and its related noun had developed a form without the initial a-, and in the late 14th century the word – maze – had begun to be applied to a deliberately confusing structure.

=> maze
ambassadoryoudaoicibaDictYouDict
ambassador: [14] Appropriately enough, ambassador is a highly cosmopolitan word. It was borrowed back and forth among several European languages before arriving in English. Its ultimate source appears to be the Indo- European root *ag- ‘drive, lead’, whose other numerous offspring include English act and agent. With the addition of the prefix *amb- ‘around’ (as in ambidextrous), this produced in the Celtic languages of Gaul the noun ambactos, which was borrowed by Latin as ambactus ‘vassal’.

The Latin word then found its way into the Germanic languages – Old English had ambeht ‘servant, messenger’, Old High German ambaht (from which modern German gets amt ‘official position’) – from which it was later borrowed back into medieval Latin as ambactia. This seems to have formed the basis of a verb, *ambactiāre ‘go on a mission’ (from which English ultimately gets embassy), from which in turn was derived the noun *ambactiātor.

This became ambasciator in Old Italian, from which Old French borrowed it as ambassadeur. The word had a be wildering array of spellings in Middle English (such as ambaxadour and inbassetour) before finally settling down as ambassador in the 16th century.

=> embassy
amberyoudaoicibaDictYouDict
amber: [14] Amber was borrowed, via Old French, from Arabic ‘anbar, which originally meant ‘ambergris’ (and in fact until the early 18th century amber was used for ‘ambergris’ too). A perceived resemblance between the two substances had already led in Arabic to ‘amber’ ousting ‘ambergris’ as the main meaning of ‘anbar, and this was reflected as soon as English acquired it.

In Scotland until as recently as the early 19th century lamber was the usual form. This arose from borrowing the French word for ‘amber’ complete with its definite article le: l’ambre. Before the introduction of the Arabic term into European languages, the ancestor of modern English glass appears to have been the word used for ‘amber’.

=> ambergris
ambergrisyoudaoicibaDictYouDict
ambergris: [15] The original term for ambergris (a waxy material from the stomach of the sperm whale) was amber. But as confusion began to arise between the two substances amber and ambergris, amber came to be used for both in all the languages that had borrowed it from Arabic, thus compounding the bewilderment. The French solution was to differentiate ambergris as ambre gris, literally ‘grey amber’, and this eventually became the standard English term. (Later on, the contrastive term ambre jaune ‘yellow amber’ was coined for ‘amber’ in French.) Uncertainty over the identity of the second element, -gris, has led to some fanciful reformulations of the word.

In the 17th century, many people thought ambergris came from Greece – hence spellings such as amber-degrece and amber-greece. And until comparatively recently its somewhat greasy consistency encouraged the spelling ambergrease.

=> amber
ambidextrousyoudaoicibaDictYouDict
ambidextrous: [16] Ambidextrous means literally ‘right-handed on both sides’. It was formed in Latin from the prefix ambi- ‘both’ and the adjective dexter ‘right-handed’ (source of English dextrous). Ambi- corresponds to the Latin adjective ambo ‘both’, which derived ultimately from the Indo-European base *amb- ‘around’ (an element in the source of ambassador and embassy).

The second element in Latin ambo seems to correspond to Old English ba ‘both’, which is related to modern English both. Other English words formed with the prefix amb(i)- include ambient [16] (which came, like ambition, from Latin ambīre ‘go round’), ambit [16] (from Latin ambitus ‘circuit’), ambiguous, ambition, amble, and ambulance.
