agoraphobia [agoraphobia 词源字典]: 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).

algorithm: 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’.

allegory: 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
category: category: [15] The word category has a rather complicated semantic history. It comes ultimately from Greek katēgorein ‘accuse’, a compound formed from the prefix katá- ‘against’ and agorá ‘public assembly’ (source of English agoraphobia and related to gregarious) – hence ‘speak against publicly’. ‘Accuse’ gradually became weakened in meaning to ‘assert, name’, and the derived noun katēgoríā was applied by Aristotle to the enumeration of all classes of things that can be named – hence ‘category’. The word reached English via late Latin catēgoria or French catégorie.
=> agoraphobia, gregarious, panegyric
clangor: clangor: see laugh
gore: gore: English has three separate words gore, two of them perhaps ultimately related. Gore ‘blood’ [OE] originally meant ‘dung, shit’, or more generally ‘filth, dirt, slime’, and related words in other languages, such as Dutch goor ‘mud, filth’, Old Norse gor ‘slime’, and Welsh gôr ‘pus’, round out a semantic picture of ‘unpleasant semi-liquid material’, with frequent specific application to ‘bodily excretions’.

It was from this background that the sense ‘blood’, and particularly ‘coagulated blood’, emerged in the mid-16th century. Gore ‘triangular piece of cloth, as let into a skirt’ [OE] comes from Old English gāra ‘triangular piece of land’ (a sense preserved in the London street-name Kensington Gore). This was related to Old English gār ‘spear’ (as in garlic; see GOAD), the semantic connection being that a spearhead is roughly triangular. Gore ‘wound with horns’ [14] originally meant simply ‘stab, pierce’; it too may come ultimately from gār ‘spear’, although there is some doubt about this.

gorge: gorge: [14] Gorge originally meant ‘throat’; the metaphorical extension to ‘rocky ravine’ did not really take place until the mid 18th century (the semantic connection was presumably ‘narrow opening between which things pass’). The word was borrowed from Old French gorge ‘throat’, which goes back via Vulgar Latin *gurga to Latin gurges ‘whirlpool’ from which English gets regurgitate [17]. The superficially similar gorgeous [15], incidentally, is not related. It was adapted from Old French gorgias ‘fine, elegant’, but no one knows where that came from.
=> regurgitate
gorilla: gorilla: [19] The first we hear of gorilla is as a word used in a Greek translation of the 5thcentury BC Carthaginian explorer Hanno’s account of a voyage to West Africa. He reported encountering there a tribe of wild hairy people, whose females were, according to a local interpreter, called goríllas. In 1847 the American missionary and scientist Thomas Savage adopted the word as the species name of the great ape Troglodytes gorilla, and by the 1850s it had passed into general use.
gorse: gorse: [OE] Gorse appears to mean etymologically ‘prickly bush’. It has been traced back to an Indo-European source *ghrzddenoting ‘roughness’ or ‘prickliness’, which also produced German gerste ‘barley’. Of the plant’s other names, furze [OE] is of unknown origin, while whin [11] was probably borrowed from a Scandinavian language.

angora (n.): type of wool, 1810, from Angora, city in central Turkey (ancient Ancyra, modern Ankara), which gave its name to the goat (1745 in English), and to its silk-like wool, and to a cat whose fur resembles it (1771 in English).

The connecting sense is "triangularity." Hence also the senses "front of a skirt" (mid-13c.), and "triangular piece of cloth" (early 14c.).

Allegedly an African word.
In its inmost recess was an island similar to that formerly described, which contained in like manner a lake with another island, inhabited by a rude description of people. The females were much more numerous than the males, and had rough skins: our interpreters called them Gorillae. We pursued but could take none of the males; they all escaped to the top of precipices, which they mounted with ease, and threw down stones; we took three of the females, but they made such violent struggles, biting and tearing their captors, that we killed them, and stripped off the skins, which we carried to Carthage: being out of provisions we could go no further.
