K is a letter of the Latin alphabet. In the English alphabet and in most European languages, it occupies the twenty-first position. Its lowercase form is "k".
In most languages that use it, K represents the voiceless velar plosive, a sound produced at the back of the mouth without vibration of the vocal cords—the sound at the beginning of the Somali word "kabo". This letter became part of the Latin-script Somali alphabet in 1972.
History
The letter's origin traces back to the Phoenician letter kaph, thought to have represented a hand. The Greeks adapted this to create kappa (Κ, κ), and the Romans took the letter from Greek, sometimes influenced by Etruscan and early Latin forms.
In early Latin, K was used sparingly because the letter C typically represented the /k/ sound. K was retained in only a few common words, such as "Kalendae". Use of K became more widespread when Germanic and northern European languages adopted the Latin alphabet, since C does not have a consistent sound value in those languages.
Language use
In German, Swedish, Polish, and Turkish, K is a regular and consistent letter. French and Italian use it selectively, mostly in borrowed words. Many African languages, including Somali and Swahili, use K as a basic letter with relatively little variation in its sound value.
Symbolic uses
K is used as a symbol in scientific fields: the unit Kelvin for temperature (K), the chemical symbol for potassium (K, from Latin kalium), and in mathematics and computing, where K often denotes one thousand or 1024. In Unicode, uppercase K is U+004B and lowercase k is U+006B.
