PARAMETER

n.[Gr. ] 1. The latus rectum of a parabola. It is a third proportional to the abscissa and any ordinate, so that the square of the ordinate is always equal to the rectangle under the parameter and abscissa; but in the ellipsis and hyperbola it has a different proportion.
2. In conic sections, a third proportional to any diameter and its conjugate. In the parabola, a third proportional to any absciss and its ordinate.

Webster's 1913 Dictionary

PARAMETER

Pa *ram "e *ter, n. Etym: [Pref. para- + -meter: cf. F. paramètre. ]

1. (a ) (Math. ) A term applied to some characteristic magnitude whose value, invariable as long as one and the same function, curve, surface, etc. , is considered, serves to distinguish that function, curve, surface, etc. , from others of the same kind or family. Brande & C. (b ) Specifically (Conic Sections ), in the ellipse and hyperbola, a third proportional to any diameter and its conjugate, or in the parabola, to any abscissa and the corresponding ordinate.

Note: The parameter of the principal axis of a conic section is called the latus rectum.

2. (Crystallog.)

Defn: The ratio of the three crystallographic axes which determines the position of any plane; also, the fundamental axial ratio for a given species.

parameter

pa ram e ter |pəˈramitər pəˈræmədər | ▶noun technical a numerical or other measurable factor forming one of a set that defines a system or sets the conditions of its operation: the transmission will not let you downshift unless your speed is within the lower gear's parameters. • Mathematics a quantity whose value is selected for the particular circumstances and in relation to which other variable quantities may be expressed. • Statistics a numerical characteristic of a population, as distinct from a statistic of a sample. • (in general use ) a limit or boundary that defines the scope of a particular process or activity: they set the parameters of the debate. ORIGIN mid 17th cent.: modern Latin, from Greek para- ‘beside ’ + metron ‘measure. ’ usage: Until recently, use of the word parameter was confined to mathematics and related technical fields. Since around the mid 20th century, however, it has been used in nontechnical fields as a technical-sounding word for ‘a limit or boundary, ’ as in they set the parameters of the debate. This use, probably influenced by the word perimeter, has been criticized for being a weakening of the technical sense. Careful writers will leave parameter to specialists in mathematics, computer science, and other technical disciplines. As a loose synonym for limit, boundary, guideline, framework, it is a vogue word that blurs more than it clarifies. Perimeter is a different word, meaning ‘border, outer boundary, or the length of such a boundary. ’

American Oxford Thesaurus

parameter

parameter noun the parameters of the debate: framework, variable, limit, boundary, limitation, restriction, criterion, guideline. WORD NOTE parameter Parameter is a technical term for a variable or an arbitrary constant that appears in a mathematical equation —its value restricts or determines the specific form of the numerical expression. Lazily equating it with perimeter, the otherwise lexically correct deploy it to mean "boundary " or "limit, " as in, I'm checking out the parameters of the debate. Stick with perimeters, or, in this example, boundaries or terms. — JS Conversational, opinionated, and idiomatic, these Word Notes are an opportunity to see a working writer's perspective on a particular word or usage.

Oxford Thesaurus

parameter

parameter noun they set the parameters of the debate: framework, variable, limit, boundary, limiting factor, limitation, restriction, specification, criterion, guideline; technical constant.
