Etymology
The letter K comes from the Greek letter kappa and has its origins in the Semitic letter kaph, which represented an open hand. It was adopted by the Romans and incorporated into the Latin alphabet. K was established as the eleventh letter of the English alphabet and typically represents the voiceless velar plosive sound (/k/), as in “kite.”
