K (named kay /ˈkeɪ/) is the eleventh letter of the ISO basic Latin alphabet.

In English, the letter K usually represents the voiceless velar plosive; this sound is also transcribed by /k/ in the International Phonetic Alphabet and X-SAMPA.

The letter K comes from the Greek letter Κ (kappa), which was taken from the Semitic kap, the symbol for an open hand. This, in turn, was likely adapted by Semites who had lived in Egypt from the hieroglyph for "hand" representing D in the Egyptian word for hand, d-r-t. The Semites evidently assigned it the sound value /k/ instead, because their word for hand started with that sound. In modern-day English slang, the word "k" is used as a substitute for the abbreviation "O.K.", or "Okay." In International Morse code it is used to mean "over".

In the earliest Latin inscriptions, the letters C, K and Q were all used to represent the sounds /k/ and /g/ (which were not differentiated in writing). Of these, Q was used to represent /k/ or /g/ before a rounded vowel, K before /a/, and C elsewhere. Later, the use of C (and its variant G) replaced most usages of K and Q. K survived only in a few fossilized forms such as Kalendae, "the calends".

In computing, a newline, also known as a line break or end-of-line (EOL) marker, is a special character or sequence of characters signifying the end of a line of text. The name comes from the fact that the next character after the newline will appear on a new line—that is, on the next line below the text immediately preceding the newline. The actual codes representing a newline vary across operating systems, which can be a problem when exchanging text files between systems with different newline representations.

There is also some confusion whether newlines terminate or separate lines. If a newline is considered a separator, there will be no newline after the last line of a file. The general convention on most systems is to add a newline even after the last line, i.e. to treat newline as a line terminator. Some programs have problems processing the last line of a file if it is not newline terminated. Conversely, programs that expect newline to be used as a separator will interpret a final newline as starting a new (empty) line.
