agoraphobia: [19] Agoraphobia – fear of open spaces or, more generally, of simply being out of doors – is first referred to in an 1873 issue of the Journal of Mental Science; this attributes the term to Dr C Westphal, and gives his definition of it as ‘the fear of squares or open places’. This would be literally true, since the first element in the word represents Greek agorá ‘open space, typically a market place, used for public assemblies’ (the most celebrated in the ancient world was the Agora in Athens, rivalled only by the Forum in Rome).

The word agorá came from ageirein ‘assemble’, which is related to Latin grex ‘flock’, the source of English gregarious. Agoraphobia was not the first of the -phobias. That honour goes to hydrophobia in the mid 16th century. But that was an isolated example, and the surge of compounds based on Greek phóbos ‘fear’ really starts in the 19th century.

At first it was used for symptoms of physical illness (photophobia ‘abnormal sensitivity to light’ 1799), for aversions to other nationalities (Gallophobia 1803; the synonymous Francophobia does not appear until 1887), and for facetious formations (dustophobia, Robert Southey, 1824), and the range of specialized psychological terms familiar today does not begin to appear until the last quarter of the century (CLAUSTROPHOBIA 1879, acrophobia ‘fear of heights’ from Greek akros ‘topmost’ – see ACROBAT – 1892).

agreeyoudaoicibaDictYouDict
agree: [14] Originally, if a thing ‘agreed you’, it was to your liking, it pleased you. This early meaning survives in the adjective agreeable [14], but the verb has meanwhile moved on via ‘to reconcile (people who have quarrelled)’ and ‘to come into accord’ to its commonest presentday sense, ‘to concur’. It comes from Old French agréer ‘to please’, which was based on the phrase a gré ‘to one’s liking’. Gré was descended from Latin grātum, a noun based on grātus ‘pleasing’, from which English also gets grace and grateful.
=> congratulate, grace, grateful, gratitude
agueyoudaoicibaDictYouDict
ague: [14] In its origins, ague is the same word as acute. It comes from the Latin phrase febris acuta ‘sharp fever’ (which found its way into Middle English as fever agu). In the Middle Ages the Latin adjective acuta came to be used on its own as a noun meaning ‘fever’; this became aguē in medieval French, from which it was borrowed into English. From the end of the 14th century ague was used for ‘malaria’ (the word malaria itself did not enter the language until the mid 18th century).
=> acute
aidyoudaoicibaDictYouDict
aid: [15] Aid comes ultimately from the same source as adjutant (which originally meant simply ‘assistant’). Latin juvāre became, with the addition of the prefix ad- ‘to’, adjuvāre ‘give help to’; from its past participle adjutus was formed a new verb, adjūtāre, denoting repeated action, and this passed into Old French as aïdier, the source of English aid.
=> adjutant, jocund
ailyoudaoicibaDictYouDict
ail: [OE] Now virtually obsolete except in the metaphorical use of its present participial adjective ailing, ail is of long but uncertain history. The Old English verb egl(i)an came from the adjective egle ‘troublesome’, which had related forms in other Germanic languages, such as Middle Low German egelen ‘annoy’ and Gothic agls ‘disgraceful’, aglo ‘oppression’. The derivative ailment did not appear until as late as the 18th century.

aileron: see aisle
aimyoudaoicibaDictYouDict
aim: [14] Etymologically, aim is a contraction of estimate (see ESTEEM). The Latin verb aestimāre became considerably shortened as it developed in the various Romance languages (Italian has stimare, for instance, and Provençal esmar). In Old French its descendant was esmer, to which was added the prefix a- (from Latin ad- ‘to’), producing aesmer; and from one or both of these English acquired aim. The notion of estimating or calculating was carried over into the English verb, but died out after about a hundred years. However, the derived sense of calculating, and hence directing, one’s course is of equal antiquity in the language.
=> esteem, estimate
airyoudaoicibaDictYouDict
air: [13] Modern English air is a blend of three strands of meaning from, ultimately, two completely separate sources. In the sense of the gas we breathe it goes back via Old French air and Latin āēr to Greek áēr ‘air’ (whence the aero-compounds of English; see AEROPLANE). Related words in Greek were áērni ‘I blow’ and aúrā ‘breeze’ (from which English acquired aura in the 18th century), and cognates in other Indo-European languages include Latin ventus ‘wind’, English wind, and nirvana ‘extinction of existence’, which in Sanskrit meant literally ‘blown out’.

In the 16th century a completely new set of meanings of air arrived in English: ‘appearance’ or ‘demeanour’. The first known instance comes in Shakespeare’s 1 Henry IV, IV, i: ‘The quality and air of our attempt brooks no division’ (1596). This air was borrowed from French, where it probably represents an earlier, Old French, aire ‘nature, quality’, whose original literal meaning ‘place of origin’ (reflected in another derivative, eyrie) takes it back to Latin ager ‘place, field’, source of English agriculture and related to acre. (The final syllable of English debonair [13] came from Old French aire, incidentally; the phrase de bon aire meant ‘of good disposition’.) The final strand in modern English air comes via the Italian descendant of Latin āēr, aria.

This had absorbed the ‘nature, quality’ meanings of Old French aire, and developed them further to ‘melody’ (perhaps on the model of German weise, which means both ‘way, manner’ and ‘tune’ – its English cognate wise, as in ‘in no wise’, meant ‘song’ from the 11th to the 13th centuries). It seems likely that English air in the sense ‘tune’ is a direct translation of the Italian.

Here again, Shakespeare got in with it first – in A Midsummer Night’s Dream, I, i: ‘Your tongue’s sweet air more tunable than lark to shepherd’s ear’ (1590). (Aria itself became an English word in the 18th century.)

aisleyoudaoicibaDictYouDict
aisle: [15] The original English form of this word was ele. It was borrowed from Old French, which in turn took it from Latin āla ‘wing’ (the modern French form of the word, aile, has a diminutive form, aileron ‘movable control surface on an aircraft’s wing’ [20], which has been acquired by English). Besides meaning literally ‘bird’s wing’, āla was used metaphorically for ‘wing of a building’, which was the source of its original meaning in English, the ‘sides of the nave of a church’.

The Latin word comes from an unrecorded *acsla, which is one of a complex web of ‘turning’ words that include Latin axis, Greek axon ‘axis’, Latin axilla ‘armpit’ (whence English axillary and axil), and English axle. The notion of an aisle as a detached, separate part of a building led to an association with isle and island which eventually affected Middle English ele’s spelling.

From the 16th to the 18th century the word was usually spelled ile or isle. A further complication entered the picture in the 18th century in the form of French aile, which took the spelling on to today’s settled form, aisle.

=> aileron, axis
ajaryoudaoicibaDictYouDict
ajar: [16] Ajar comes from Scotland and Northern England. In Middle English times it was a char or on char, literally ‘on turn’ (char comes from an Old English word cerr ‘turn’, which in its metaphorical sense ‘turn of work’ has given modern English charwoman and chore). A door or window that was in the act of turning was therefore neither completely shut nor completely open. The first spellings with j occur in the 18th century.
=> char, charwoman
akimboyoudaoicibaDictYouDict
akimbo: [15] Akimbo was borrowed from Old Norse. Its original English spelling (which occurs only once, in the Tale of Beryn 1400) was in kenebowe, which suggests a probable Old Norse precursor *i keng boginn (never actually discovered), meaning literally ‘bent in a curve’ (Old Norse bogi is related to English bow); hence the notion of the arms sticking out at the side, elbows bent. When the word next appears in English, in the early 17th century, it has become on kenbow or a kenbo, and by the 18th century akimbo has arrived.
=> bow
alabasteryoudaoicibaDictYouDict
alabaster: [14] Chaucer was the first English author to use the word alabaster: in the Knight’s Tale (1386) he writes of ‘alabaster white and red coral’. It comes, via Old French and Latin, from Greek alábast(r)os, which may be of Egyptian origin. Scottish English used the variant from alabast until the 16th century (indeed, this may predate alabaster by a few years); and from the 16th to the 17th century the word was usually spelled alablaster, apparently owing to confusion with arblaster ‘crossbowman’.

The use of alabaster for making marbles (of the sort used in children’s games) gave rise to the abbreviation alley, ally ‘marble’ in the early 18th century.

alarmyoudaoicibaDictYouDict
alarm: [14] Alarm was originally a call to arms. It comes from the Old Italian phrase all’ arme ‘to the weapons!’ This was lexicalized as the noun allarme, which was borrowed into Old French as alarme, and thence into English. The archaic variant alarum seems to have arisen from an emphatic rolling of the r accompanying a prolongation of the final syllable when the word was used as an exclamation.
=> arm
alasyoudaoicibaDictYouDict
alas: [13] In origin alas was an exclamation of weariness rather than grief. Latin lassus ‘weary’ (related to let ‘allow’ and source of lassitude) passed into Old French as las which, with the addition of the exclamation a ‘ah’, became alas.
=> lassitude, let
albatrossyoudaoicibaDictYouDict
albatross: [17] The word albatross has a confused history. The least uncertain thing about it is that until the late 17th century it was alcatras; the change of the first element to albaseems to have arisen from association of the albatross’s white colour with Latin albus ‘white’. However, which particular bird the alcatras was, and where the word alcatras ultimately came from, are much more dubious.

The term was applied variously, over the 16th to the 19th centuries, to albatrosses, frigate birds, gannets, gulls, and pelicans. Its immediate source was Spanish and Portuguese alcatraz ‘pelican’ (hence Alcatraz, the prison-island in San Francisco Bay, USA, once the haunt of pelicans), which was clearly of Arabic origin, and it has been speculated that it comes from Arabic al qādūs ‘the bucket’, on the premise that the bucket of a water-wheel used for irrigation resembles a pelican’s beak.

Arabic qādūs itself comes from Greek kádos ‘jar’.

albinoyoudaoicibaDictYouDict
albino: [18] Like album, albino comes ultimately from Latin albus ‘white’. It was borrowed into English from the Portuguese, who used it with reference to black Africans suffering from albinism (it is a derivative of albo, the Portuguese descendant of Latin albus).
=> album
albumyoudaoicibaDictYouDict
album: [17] Latin albus ‘white’ has been the source of a variety of English words: alb ‘ecclesiastical tunic’ [OE], albedo ‘reflective power’ [19], Albion [13], an old word for Britain, probably with reference to its white cliffs, albumen ‘white of egg’ [16], and auburn, as well as albino. Album is a nominalization of the neuter form of the adjective, which was used in classical times for a blank, or white, tablet on which public notices were inscribed.

Its original adoption in the modern era seems to have been in Germany, where scholars kept an album amicorum ‘album of friends’ in which to collect colleagues’ signatures. This notion of an autograph book continues in Dr Johnson’s definition of album in his Dictionary 1755: ‘a book in which foreigners have long been accustomed to insert the autographs of celebrated people’, but gradually it became a repository for all sorts of souvenirs, including in due course photographs.

=> alb, albedo, albino, albumen, auburn, daub
alchemyyoudaoicibaDictYouDict
alchemy: [14] Alchemy comes, via Old French alkemie and medieval Latin alchimia, from Arabic alkīmīā. Broken down into its component parts, this represents Arabic al ‘the’ and kīmīā, a word borrowed by Arabic from Greek khēmíā ‘alchemy’ – that is, the art of transmuting base metals into gold. (It has been suggested that khēmīā is the same word as Khēmīā, the ancient name for Egypt, on the grounds that alchemy originated in Egypt, but it seems more likely that it derives from Greek khūmós ‘fluid’ – source of English chyme [17] – itself based on the verb khein ‘pour’).

Modern English chemistry comes not directly from Greek khēmíā, but from alchemy, with the loss of the first syllable.

=> chemistry, chyme
alcoholyoudaoicibaDictYouDict
alcohol: [16] Originally, alcohol was a powder, not a liquid. The word comes from Arabic alkuhul, literally ‘the kohl’ – that is, powdered antimony used as a cosmetic for darkening the eyelids. This was borrowed into English via French or medieval Latin, and retained this ‘powder’ meaning for some centuries (for instance, ‘They put between the eyelids and the eye a certain black powder made of a mineral brought from the kingdom of Fez, and called Alcohol’, George Sandys, Travels 1615).

But a change was rapidly taking place: from specifically ‘antimony’, alcohol came to mean any substance obtained by sublimation, and hence ‘quintessence’. Alcohol of wine was thus the ‘quintessence of wine’, produced by distillation or rectification, and by the middle of the 18th century alcohol was being used on its own for the intoxicating ingredient in strong liquor.

The more precise chemical definition (a compound with a hydroxyl group bound to a hydrocarbon group) developed in the 19th century.

=> kohl
alcoveyoudaoicibaDictYouDict
alcove: [17] Alcove is of Arabic origin. It reached English, via French alcôve and Spanish alcoba (where it means ‘recessed area for a bed’), from Arabic al-qobbah ‘the arch, the vault’, hence ‘the vaulted room’, which was derived from the verb qubba ‘vault’.
