    the eleventh letter of the English alphabet, is nonvocal consonant. The form and sound of the letter K are from the Latin, which used the letter but little except in the early period of the language. It came into the Latin from the Greek, which received it from a Phœnician source, the ultimate origin probably being Egyptian. Etymologically K is most nearly related to c, g, h (which see).
