In typography, small capitals (usually abbreviated small caps) are uppercase (''capital'') characters set at the same height and weight as surrounding lowercase (''small'') letters or text figures. They are used in running text to prevent capitalized words from appearing too large on the page, and as a method of emphasis or distinctiveness for text alongside or instead of italics, or when boldface is inappropriate. For example, the all-caps TEXT IN CAPS appears as in small caps. They can be used to draw attention to the opening phrase or line of a new section of text, or to provide an additional style in a dictionary entry where many parts must be typographically differentiated. Well-designed small capitals are not simply scaled-down versions of normal capitals; they normally retain the same stroke weight as other letters and have a wider aspect ratio for readability. Typically, the height of a small capital will be one ex, the same height as most lowercase characters in the font. In Anglo-Saxon typography, small caps are somewhat larger than the x-height. For example, in some Tiro Typeworks fonts, small caps are 30% larger than x-height, and 70% the height of full capitals. To differentiate between these two alternatives, the x-height form is sometimes called petite caps, preserving the name "small caps" for the larger variant. OpenType fonts can define both forms via the "small caps" and the "petite caps" features. Because the support for the petite caps feature is absent from most desktop-publishing programs, many fonts use x-height small caps in the small-caps feature. Many word processors and text-formatting systems include an option to format text in caps and small caps, which leaves uppercase letters as they are, but converts lowercase letters to small caps. How this is implemented depends on the typesetting system; some can use true small caps associated with modern professional fonts, making text such as "Latvia joined on March 29, 2004" look proportional; but less complex digital fonts do not have a small-caps case, so the typesetting system simply reduces the uppercase letters by a fraction, making them look out of proportion. A work-around to simulate real small capitals is to use a one-level bolder version of the small caps generated by such systems, to match well with the normal weights of capitals and lowercase, especially when such small caps are extended about 5% or letterspaced a half point or a point. ==Uses== Small caps are often used for sections of text that is all uppercase; this makes the run of capital letters seem less jarring to the reader. For example, the style of many American publications, including the ''Atlantic Monthly'' and ''USA Today'', is to use small caps for acronyms and initialisms longer than three letters—thus "U.S." in normal caps, but "" in small caps. The initialisms , , , and are often smallcapped. In printed plays and stage directions, small caps are usually used for the names of characters before their lines. French and some British publications use small caps to indicate the surname by which someone with a long formal name is to be designated in the rest of a written work. An elementary example is . Similarly, they are used for those languages in which the surname comes first, such as the Romanization . In many versions of the Old Testament of the Bible, the word "" is set in small caps. Typically, an ordinary "Lord" corresponds to the use of the word ''Adonai'' in the original Hebrew, but the small caps "" corresponds to the use of ''Yahweh'' in the original; in some versions the compound "Lord " represents the Hebrew compound ''Adonai Yahweh''. In zoological and botanical nomenclature, it is common use to print names of the family group in small caps. Linguists use small caps to analyze the morphology and tag (gloss) the parts of speech in a sentence; e.g., : ''The Bluebook'' prescribes small caps for some titles in United States legal citations. In many books, when one part of the book mentions another part of the same book, or mentions the work as a whole, the name is set in small caps (sometimes with normal capitals for the initial letters of certain words in the title), not italics and not roman type within quotation marks. For example, articles in ''The World Book Encyclopedia'' refer to the encyclopedia as a whole and to the encyclopedia's other articles in small caps, as in the "Insurance" article's direction, at one point, to "See ", "No-Fault Insurance" being another of the encyclopedia's articles. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「small caps」の詳細全文を読む スポンサード リンク
