Oxford English Dictionary in the context of "Giga-"

The Western world, also known as the West, primarily refers to various nations and states in Western Europe, Northern America, and Australasia; with some debate as to whether those in Eastern Europe and Latin America also constitute the West. The Western world likewise is called the Occident (from Latin occidens 'setting down, sunset, west') in contrast to the Eastern world known as the Orient (from Latin oriens 'origin, sunrise, east'). Definitions of the "Western world" vary according to context and perspectives; the West is an evolving concept made up of cultural, political, and economic synergy among diverse groups of people, and not a rigid region with fixed borders and members.

Some historians contend that a linear development of the West can be traced from Ancient Greece and Rome, while others argue that such a projection constructs a false genealogy. A geographical concept of the West started to take shape in the 4th century CE when Constantine, the first Christian Roman emperor, divided the Roman Empire between the Greek East and Latin West. The East Roman Empire, later called the Byzantine Empire, continued for a millennium, while the West Roman Empire lasted for only about a century and a half. Significant theological and ecclesiastical differences led Western Europeans to consider the Christians in the Byzantine Empire as heretics. In 1054 CE, when the church in Rome excommunicated the patriarch of Byzantium, the politico-religious division between the Western church and Eastern church culminated in the Great Schism or the East–West Schism. Even though friendly relations continued between the two parts of Christendom for some time, the crusades made the schism definitive with hostility. The West during these crusades tried to capture trade routes to the East and failed, it instead discovered the Americas. In the aftermath of the European colonization of the Americas, primarily involving Western European powers, an idea of the "Western" world, as an inheritor of Latin Christendom emerged. According to the Oxford English Dictionary, the earliest reference to the term "Western world" was from 1586, found in the writings of William Warner.

British English is the set of varieties of the English language native to the United Kingdom, especially Great Britain. More narrowly, it can refer specifically to the English language in England, or, more broadly, to the collective dialects of English throughout the United Kingdom taken as a single umbrella variety, for instance additionally incorporating Scottish English, Welsh English, and Northern Irish English. Tom McArthur in the Oxford Guide to World English acknowledges that British English shares "all the ambiguities and tensions [with] the word 'British' and as a result can be used and interpreted in two ways, more broadly or more narrowly, within a range of blurring and ambiguity".

Variations exist in formal (both written and spoken) English in the United Kingdom. For example, the adjective wee is almost exclusively used in parts of Scotland, north-east England, Northern Ireland, Ireland, and occasionally Yorkshire, whereas the adjective little is predominant elsewhere. Nevertheless, there is a meaningful degree of uniformity in written English within the United Kingdom, and this could be described by the term British English. The forms of spoken English, however, vary considerably more than in most other areas of the world where English is spoken and so a uniform concept of British English is more difficult to apply to the spoken language.

Subsidiarity is a principle of social organization that holds that social and political issues should be dealt with at the most immediate or local level that is consistent with their resolution. The Oxford English Dictionary defines subsidiarity as "the principle that a central authority should have a subsidiary function, performing only those tasks which cannot be performed at a more local level". The concept is applicable in the fields of government, political science, neuropsychology, cybernetics, management and in military command (mission command). The OED adds that the term "subsidiarity" in English follows the early German usage of "Subsidiarität". More distantly, it is derived from the Latin verb subsidio (to aid or help), and the related noun subsidium (aid or assistance).

The development of the concept of subsidiarity has roots in the natural law philosophy of Thomas Aquinas and was mediated by the social scientific theories of Luigi Taparelli, SJ, in his 1840–43 natural law treatise on the human person in society. In that work, Taparelli established the criteria of just social order, which he referred to as "hypotactical right" and which came to be termed "subsidiarity" following German influences.

Rhythm (from Greek ῥυθμός, rhythmos, "any regular recurring motion, symmetry") generally means a "movement marked by the regulated succession of strong and weak elements, or of opposite or different conditions". This general meaning of regular recurrence or pattern in time can apply to a wide variety of cyclical natural phenomena having a periodicity or frequency of anything from microseconds to several seconds (as with the riff in a rock music song); to several minutes or hours, or, at the most extreme, even over many years.

The Oxford English Dictionary defines rhythm as "The measured flow of words or phrases in verse, forming various patterns of sound as determined by the relation of long and short or stressed and unstressed syllables in a metrical foot or line; an instance of this".

Harlequinade is an English comic theatrical genre, defined by the Oxford English Dictionary as "that part of a pantomime in which the harlequin and clown play the principal parts". It developed in England between the 17th and mid-19th centuries. It was originally a slapstick adaptation or variant of the commedia dell'arte, which originated in Italy and reached its apogee there in the 16th and 17th centuries. The story of the Harlequinade revolves around a comic incident in the lives of its five main characters: Harlequin, who loves Columbine; Columbine's greedy and foolish father Pantaloon (evolved from the character Pantalone), who tries to separate the lovers in league with the mischievous Clown; and the servant, Pierrot, usually involving chaotic chase scenes with a bumbling policeman.

Originally a mime (silent) act with music and stylised dance, the harlequinade later employed some dialogue, but it remained primarily a visual spectacle. Early in its development, it achieved great popularity as the comic closing part of a longer evening of entertainment, following a more serious presentation with operatic and balletic elements. An often elaborate magical transformation scene, presided over by a fairy, connected the unrelated stories, changing the first part of the pantomime, and its characters, into the harlequinade. In the late 18th and 19th centuries, the harlequinade became the larger part of the entertainment, and the transformation scene was presented with increasingly spectacular stage effects. The harlequinade lost popularity towards the end of the 19th century and disappeared altogether in the 1930s, although Christmas pantomimes continue to be presented in Britain without the harlequinade.

A paramilitary is a force or unit that functions and is organized in a manner analogous to a military force, but does not have professional or legitimate status. The Oxford English Dictionary traces the use of the term "paramilitary" as far back as 1934.

An antiquarian or antiquary (from Latin antiquarius 'pertaining to ancient times') is an aficionado or student of antiquities or things of the past. More specifically, the term is used for those who study history with particular attention to ancient artefacts, archaeological and historic sites, or historic archives and manuscripts. The essence of antiquarianism is a focus on the empirical evidence of the past, and is perhaps best encapsulated in the motto adopted by the 18th-century antiquary Sir Richard Colt Hoare, "We speak from facts, not theory."

The Oxford English Dictionary first cites "archaeologist" from 1824; this soon took over as the usual term for one major branch of antiquarian activity. "Archaeology", from 1607 onwards, initially meant what is now seen as "ancient history" generally, with the narrower modern sense first seen in 1837.

The Concise Oxford English Dictionary (officially titled The Concise Oxford Dictionary until 2002, and widely abbreviated COD or COED) is one of the best-known of the 'smaller' Oxford dictionaries. The latest edition contains over 240,000 entries and 1,728 pages ("concise" compared to the OED at over 21,000 pages). Its 12th edition, published in 2011, is used by both the United Nations (UN) and NATO as the current authority for spellings in documents in English for international use. It is available as an e-book for a variety of handheld device platforms. In addition to providing information for general use, it documents local variations such as United States and United Kingdom usage.

It was started as a derivative of the Oxford English Dictionary (OED), although section S–Z had to be written before the Oxford English Dictionary reached that stage. However, starting from the 10th edition, it is based on the Oxford Dictionary of English (ODE) rather than the OED. The most recent edition is the 12th, published in 2011.
