Word Origin and History for k

K

Roman letter, from Greek kappa, ultimately from Phoenician and general Semitic kaph, said to be literally "hollow of the hand," so called for its shape. For more on the history of its use, see see C. As a symbol for potassium, it represents Latin kalium "potash." Slang meaning "one thousand dollars" is 1970s, from kilo-. As an indication of "strikeout" in baseball scorekeeping it dates from 1874, said to be from last letter of struck, perhaps because first letter already was being used as abbreviation for sacrifice. The invention of the scorecard symbols is attributed to U.S. newspaperman Henry Chadwick (1824-1908) of the old New York "Clipper."

Smith was the first striker, and went out on three strikes, which is recorded by the figure "1" for the first out, and the letter K to indicate how put out, K being the last letter of the word "struck." The letter K is used in this instance as being easier to remember in connection with the word struck than S, the first letter, would be. [Henry Chadwick, "Chadwick's Base Ball Manual," London, 1874]
K as a measure of capacity (especially in computer memory) or number (especially of salary), meaning "one thousand" is an abbreviation of kilo.

kappa

tenth letter of the Greek alphabet, from an Aramaized form of qoph; see K.

Encyclopedia Article for k

kappa

in Japanese folklore, a type of vampirelike lecherous creature that is more intelligent than the devilish oni (q.v.) and less malevolent toward men. Kappa are credited with having taught the art of bonesetting to humans. They are depicted in legend and art as being the size of a 10-year-old child, yellow-green in colour, and resembling monkeys, but with fish scales or tortoise shells instead of skin. On the top of their head they have hollow indentations that are filled with water; if the water is spilled, they are said to lose their supernatural powers. Legends of encounters with kappa invariably include a reference to their capacity for keeping a promise, extracted from them after forcing their heads down or by tricking them into bowing low, thus spilling out the water. They have a taste for cucumbers, and a standard way of placating kappa is to throw a cucumber into the water where they live
