English[edit]
Etymology[edit]
From Latin normālis (“made according to a carpenter’s square; later: according to a rule”), from nōrma (“carpenter’s square”), of uncertain origin.^{[1]}^{[2]}^{[3]}^{[4]} The earliest use of the word in English was to mean “perpendicular; forming a right angle” like something normālis (“made according to a carpenter’s square”),^{[1]}^{[5]} but by Late Latin normālis had also come to mean “according to a rule”, from which modern English senses of the word derive:^{[5]} in the 1800s, as people began to quantitatively study things like height and weight and blood pressure, the usual or most common values came to be referred to as “normal”, and by extension values regarded as healthy or desirable came to be called “normal” regardless of their usuality.^{[6]}

 (mathematics) Adhering to or being what is considered natural or regular in a particular field or context:
 (number theory, of a real number) In whose representation in a given base b ≥ 2, for every positive integer n, the b^{n} possible strings of n digits follow a uniform distribution.

A number whose individual digits in a given base representation follow a uniform distribution is said to be simply normal.

A number that is normal for every base b ≥ 2 is said to be absolutely normal.

 (algebra, of a subgroup) With cosets which form a group.
 (algebra, of a field extension of a field K) Which is the splitting field of a family of polynomials in K.

 (rail transport, of points) In the default position, set for the most frequently used route.
 (geometry) Perpendicular to a tangent of a curve or derivative of a surface.
 The interior normal vector of an ideal perfect sphere will always point toward the center, and the exterior normal vector directly away, and both will always be colinear with the ray whose’ tip ends at the point of intersection, which is the intersection of all three sets of points.
Usage notes[edit]
 When used to describe a group of people, normal can be understood as meaning that those not part of the group are strange or freakish. Its usage can therefore be understood as offensive to those it excludes.
