Meaning
Formerly, k was added to c, in certain words of Latin origin, as in musick, publick, republick. but in modern practice, k is very properly omitted, being entirely superfluous, and the more properly, as it is never written in the derivatives, musical, publication, republican. It is retained in traffick, as in monosyllables, on account of the pronunciation of the derivatives, trafficked, trafficking.
K is silent before n, as in know, knife, knee. As a numeral, K stands for 250; and with a stroke over it, for 250,000. This character was not used by the ancient Romans, and rarely in the later ages of their empire. In the place of k, they used c, as in clino, for Greek. In the Teutonic dialects, this Greek letter is sometimes represented by h. [See H.]
