X

Small-cap X (left) and lower-case x (right) are distinct when italic, which is the convention of several phonetic alphabets. X is the only small-capital letter of the basic Latin alphabet that is not included in Unicode.

Translingual

Etymology 1

Letter

1. The twenty-fourth letter of the basic modern Latin alphabet.

Etymology 2

The variable name comes from usage in Spain, as up to the 16th century ⟨x⟩ had the sound value Template:IPAchar in Template:Bor, so was used to transcribe Template:Der used for the purpose of a variable as an abbreviation of Template:M. Its sound value in Spanish has since then become Template:IPAchar, which explains the decision Template:W in the circle of the Template:W to assign this character to the voiceless velar fricative. Compare Template:Ncog for the development of the sense of a communicated kiss.

Usage notes

Using Template:M (in upper- or lower-case, italicized or not, and sometimes rotated 90 degrees) to indicate multiplication was common in 17th-century mathematical texts. Today, this usage is considered poor typography, but it is nevertheless common because computer keyboards lack a Template:Angbr key.

Etymology 4

A CD-R claiming 52X speed.

A DVD-R claiming 8x speed.

Originates in given multiples of the speeds specified in the original CD and DVD standards, then, by reason of the actual unit being without name but just implied by the multiplication sign, reinterpreted as or used as if a unit, considering also that data transfer speed is variable, so that now, bolstered by stylization of the sign in the marketing of manufacturers, either spelling, with the multiplication sign or with the ex borrowed from the iconic mathematical variable sign, seems correct.

Symbol

1. Template:Lb A unit of transfer rate of CD drives, equal to 150 KiB per second.
2. Template:Lb A unit of transfer rate of DVD drives, equal 1.32 MiB per second.
