字母k

K \K\, (k[=a]),
   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 Ph[oe]nician source, the
   ultimate origin probably being Egyptian. Etymologically K is
   most nearly related to c, g, h (which see).

   Note: In many words of one syllable k is used after c, as in
         crack, check, deck, being necessary to exhibit a
         correct pronunciation in the derivatives, cracked,
         checked, decked, cracking; since without it, c, before
         the vowels e and i, would be sounded like s. Formerly,
         k was added to c in certain words of Latin origin, as
         in musick, publick, republick; but now it is omitted.

   Note: See Guide to Pronunciation, [sect][sect] 240, 178, 179,
         185.
