Specifically: A distinct part or portion of a book or writing; a subdivision of a chapter; the division of a law or other writing; a paragraph; an article; hence, the character, often used to denote such a division.

(Locke) A distinct part of a country or people, community, class, or the like; a part of a territory separated by geographical lines, or of a people considered as distinct. "The extreme section of one class consists of bigoted dotards, the extreme section of the other consists of shallow and reckless empirics."

In mechanical drawing, as in these Illustrations of a cannon, a longitudinal section (a) usually represents the object as cut through its center lengthwise and vertically; a cross or transverse section (b), as cut crosswise and vertically; and a horizontal section (c), as cut through its center horizontally. Oblique sections are made at various angles. In architecture, a vertical section is a drawing showing the interior, the thickness of the walls, ets, as if made on a vertical plane passed through a building. <mathematics> Angular sections, an instrument to aid in drawing a series of equidistant parallel lines, used in representing sections.

Section, Part. The English more commonly apply the word section to a part or portion of a body of men; as, a section of the clergy, a small section of the Whigs, etc. In the United States this use is less common, but another use, unknown or but little known in England, is very frequent, as in the phrases "the eastern section of our country," etc, the same sense being also given to the adjective sectional as, sectional feelings, interests, etc. Origin: L. Sectio, fr. Secare, sectum, to cut; akin to E. Saw a cutting instrument: cf. F. Section. See Saw, and cf. Scion, Dissect, Insect, Secant, Segment. Source: Websters Dictionary (01 Mar 1998) |
| section, caesarian | Procedure in which an infant, rather than being born vaginally, is surgically removed from the uterus. As the name caesarian suggests, this is not a new procedure. It was done in ancient civilizations upon the death of a pregnant woman near term to salvage the baby. Julius caesar (or, more likely, one of his predecessors) was born by this procedure. The term section in surgery refers to the division of tissue. What is being divided here is the abdominal wall of the mother and the wall of the uterus in order to extract the baby. In shakespeare's macbeth the witches' prophecy was that..none of woman born/ shall harm macbeth (iv.i). Unfortunately for macbeth, the scottish nobleman macduff was from his mother's womb/ untimely ripped. And thus not naturally born of woman (v.vii). Macduff is the only agent capable of destroying macbeth. He kills macbeth in battle. (12 Dec 1998) |
