alderyoudaoicibaDictYouDict[alder 词源字典]
alder: [OE] Alder is an ancient tree-name, represented in several other Indo-European languages, including German erle, Dutch els, Polish olcha, Russian ol’khá, and Latin alnus (which is the genus name of the alder in scientific classification). Alder is clearly the odd man out amongst all these forms in having a d, but it was not always so; the Old English word was alor, and the intrusive d does not begin to appear until the 14th century (it acts as a sort of connecting or glide consonant between the l and the following vowel, in much the same way as Old English thunor adopted a d to become thunder). The place-name Aldershot is based on the tree alder.

aldermanyoudaoicibaDictYouDict
alderman: [OE] Alderman preserves the notion that those who are old (the ‘elders’) are automatically in charge. In Anglo-Saxon England the ealdor was the chief of a family or clan, by virtue of seniority (the word is based on the adjective eald ‘old’). Alderman (Old English ealdorman) was a political title or rank adopted probably in the early 8th century for someone who exercised in society at large an authority equivalent to that of the ealdor.

In effect, this meant that an alderman acted as a sort of viceroy to the king in a particular district. In the 12th century the title became applied to the governor of a guild, and as the guilds gradually took over some functions of local government, an alderman became a senior councillor. The title was officially abolished in Britain in 1974.

ale: [OE] Old English ealu ‘ale’ goes back to a Germanic root *aluth-, which also produced Old Norse öl (Scandinavian languages still use alerelated words, whereas other Germanic languages now only use beer-related words; English is the only one to retain both). Going beyond Germanic in time takes us back to the word’s ultimate Indo-European source, a base meaning ‘bitter’ which is also represented in alum and aluminium. Ale and beer seem to have been virtually synonymous to the Anglo- Saxons; various distinctions in usage have developed over the centuries, such as that ale is made without hops, and is heavier (or some would say lighter) than beer, but most of the differences have depended on local usage.

The word bridal is intimately connected with ale. Nowadays used as an adjective, and therefore subconsciously associated with other adjectives ending in -al, in Old English it was a noun, literally ‘bride ale’, that is, a beer-drinking session to celebrate a marriage.

alert: [17] Alert comes, via French, from an Italian phrase all’ erta ‘on the look-out’, or literally ‘at the (alla) watch-tower (erta)’. Erta was short for torre erta, literally ‘high tower’, in which the adjective erta ‘high’ came ultimately from Latin ērectus, the past participle of ērigere ‘raise’.

alexandrine: [16] An alexandrine is a line of verse of 12 syllables, characteristic of the classic French drama of the 17th century. The term derives from the use of this metre in Alexandre, a 12th-or 13th-century Old French romance about Alexander the Great.

algebra: [16] Algebra symbolizes the debt of Western culture to Arab mathematics, but ironically when it first entered the English language it was used as a term for the setting of broken bones, and even sometimes for the fractures themselves (‘The helpes of Algebra and of dislocations’, Robert Copland, Formulary of Guydo in surgery 1541). This reflects the original literal meaning of the Arabic term al jebr, ‘the reuniting of broken parts’, from the verb jabara ‘reunite’.

The anatomical connotations of this were adopted when the word was borrowed, as algebra, into Spanish, Italian, and medieval Latin, from one or other of which English acquired it. In Arabic, however, it had long been applied to the solving of algebraic equations (the full Arabic expression was ’ilm aljebr wa’lmuqābalah ‘the science of reunion and equation’, and the mathematician al- Khwarizmi used aljebr as the title of his treatise on algebra – see ALGORITHM), and by the end of the 16th century this was firmly established as the central meaning of algebra in English.

algorithmyoudaoicibaDictYouDict
algorithm: [13] Algorithm comes from the name of an Arab mathematician, in full Abu Ja far Mohammed ibn-Musa al-Khwarizmi (c. 780–c. 850), who lived and taught in Baghdad and whose works in translation introduced Arabic numerals to the West. The last part of his name means literally ‘man from Khwarizm’, a town on the borders of Turkmenistan, now called Khiva. The Arabic system of numeration and calculation, based on 10, of which he was the chief exponent, became known in Arabic by his name – al-khwarizmi.

This was borrowed into medieval Latin as algorismus (with the Arabic -izmi transformed into the Latin suffix -ismus ‘-ism’). In Old French algorismus became augorime, which was the basis of the earliest English form of the word, augrim. From the 14th century onwards, Latin influence gradually led to the adoption of the spelling algorism in English.

This remains the standard form of the word when referring to the Arabic number system; but in the late 17th century an alternative version, algorithm, arose owing to association with Greek árithmos ‘number’ (source of arithmetic [13]), and this became established from the 1930s onwards as the term for a stepby- step mathematical procedure, as used in computing. Algol, the name of a computer programming language, was coined in the late 1950s from ‘algorithmic language’.

alibiyoudaoicibaDictYouDict
alibi: [18] In Latin, alibi means literally ‘somewhere else’. It is the locative form (that is, the form expressing place) of the pronoun alius ‘other’ (which is related to Greek allos ‘other’ and English else). When first introduced into English it was used in legal contexts as an adverb, meaning, as in Latin, ‘elsewhere’: ‘The prisoner had little to say in his defence; he endeavoured to prove himself Alibi’, John Arbuthnot, Law is a bottomless pit 1727.

But by the end of the 18th century it had become a noun, ‘plea of being elsewhere at the time of a crime’. The more general sense of an ‘excuse’ developed in the 20th century. Another legal offspring of Latin alius is alias. This was a direct 16th-century borrowing of Latin aliās, a form of alius meaning ‘otherwise’.

=> alias, else
alienyoudaoicibaDictYouDict
alien: [14] The essential notion contained in alien is of ‘otherness’. Its ultimate source is Latin alius ‘other’ (which is related to English else). From this was formed a Latin adjective aliēnus ‘belonging to another person or place’, which passed into English via Old French alien. In Middle English an alternative version alient arose (in the same way as ancient, pageant, and tyrant came from earlier ancien, pagin, and tyran), but this died out during the 17th century.

The verb alienate ‘estrange’ or ‘transfer to another’s ownership’ entered the language in the mid 16th century, eventually replacing an earlier verb alien (source of alienable and inalienable).

=> alibi, else

alike: [OE] Alike is an ancient word whose ultimate Germanic source, *galīkam, meant something like ‘associated form’ (*līkam ‘form, body’ produced German leiche ‘corpse’ and Old English lic, from which we get lychgate, the churchyard gate through which a funeral procession passes; and the collective prefix *gameant literally ‘with’ or ‘together’).

In Old English, *galīkam had become gelīc, which developed into Middle English ilik; and from the 14th century onwards the prefix i-, which was becoming progressively rarer in English, was assimilated to the more familiar a-. The verb like is indirectly related to alike, and the adjective, adverb, preposition, and conjunction like was formed directly from it, with the elimination of the prefix.

=> each, like
alimonyyoudaoicibaDictYouDict
alimony: [17] Alimony is an anglicization of Latin alimōnia, which is based on the verb alere ‘nourish’ (source of alma ‘bounteous’, as in alma mater, and of alumnus). This in turn goes back to a hypothetical root *al-, which is also the basis of English adolescent, adult, altitude (from Latin altus ‘high’), and old.

The original sense ‘nourishment, sustenance’ has now died out, but the specialized ‘support for a former wife’ is of equal antiquity in English. The -mony element in the word represents Latin -mōnia, a fairly meaning-free suffix used for forming nouns from verbs (it is related to -ment, which coincidentally was also combined with alere, to form alimentary), but in the later 20th century it took on a newly productive role in the sense ‘provision of maintenance for a former partner’. Palimony ‘provision for a former non-married partner’ was coined around 1979, and in the 1980s appeared dallymony ‘provision for somebody one has jilted’.

=> adult, altitude, alumnus, old

alive: [OE] Alive comes from the Old English phrase on life, literally ‘on life’. Līfe was the dative case of līf ‘life’; between two vowels f was pronounced /v/ in Old English, hence the distinction in modern English pronunciation between life and alive.

alkaliyoudaoicibaDictYouDict
alkali: [14] English acquired alkali via Latin from Arabic al-qalīy ‘the ashes’, a derivative of the verb qalay ‘fry’. The implicit reference is to the plant saltwort (Latin name Salsola kali), which was burnt to obtain its alkaline ashes (Chaucer’s canon’s yeoman, the alchemist’s assistant, mentions it: ‘Salt tartre, alcaly, and salt preparat, And combust matieres, and coagulat’, 1386). The modern chemical sense of a compound which combines with an acid to form a salt was first used in 1813, by the chemist Sir Humphry Davy.
allyoudaoicibaDictYouDict
all: [OE] Words related to all are found throughout the Germanic languages (German all, Dutch al, Old Norse allr, Gothic alls, for instance). They can probably all be traced back to a hypothetical Germanic ancestor *alnaz. Connections outside Germanic are not known, unless Lithuanian aliai ‘completely’ is a relative.
allayyoudaoicibaDictYouDict
allay: [OE] In Old English, alecgan meant literally ‘lay aside’ (-a ‘away, aside, out’, lecgan ‘lay’). The more recent senses ‘relieve, mitigate’ developed from the 13th to the 15th centuries owing to the influence of two formally similar Old French verbs: aleger ‘lighten’ (from Latin alleviāre, source of English alleviate [15]); and al(e)ier ‘qualify, moderate’ (source of English alloy).
=> lay
allegeyoudaoicibaDictYouDict
allege: [14] Allege is related to law, legal, legislation, legation, and litigation. Its original source was Vulgar Latin *exlitigāre, which meant ‘clear of charges in a lawsuit’ (from ex- ‘out of’ and litigāre ‘litigate’). This developed successively into Old French esligier and Anglo- Norman alegier, from where it was borrowed into English; there, its original meaning was ‘make a declaration before a legal tribunal’.

Early traces of the notion of making an assertion without proof can be detected within 50 years of the word’s introduction into English, but it took a couple of centuries to develop fully. The hard g of allegation suggests that though it is ultimately related to allege, it comes from a slightly different source: Latin allēgātiō, from allēgāre ‘adduce’, a compound verb formed from ad- ‘to’ and lēgāre ‘charge’ (source of English legate and legation).

=> law, legal, legation, legislation, litigation
allegoryyoudaoicibaDictYouDict
allegory: [14] Etymologically, allegory means ‘speaking otherwise’. It comes from a Greek compound based on allos ‘other’ (which is related to Latin alius, as in English alibi and alias, and to English else) and agoreúein ‘speak publicly’ (derived from agorá ‘(place of) assembly’, which is the source of English agoraphobia and is related to gregarious). Greek allēgorein ‘speak figuratively’ produced the noun allēgorīā, which passed into English via Latin and French.
=> aggregate, agoraphobia, alias, alibi, else, gregarious
allergyyoudaoicibaDictYouDict
allergy: [20] Allergy was borrowed from German allergie, which was coined in 1906 by the scientist C E von Pirquet. He formed it from Greek allos ‘other, different’ and érgon ‘work’ (source of English energy and related to English work). Its original application was to a changed physiological condition caused by an injection of some foreign substance.
=> energy, work
alleyyoudaoicibaDictYouDict
alley: [14] Alley is related to French aller ‘go’. Old French aler (which came from Latin ambulāre ‘walk’, source of English amble and ambulance) produced the derived noun alee ‘act of walking’, hence ‘place where one walks, passage’.
=> amble, ambulance
