U+039A "Κ" Greek Capital Letter Kappa Unicode Character

U+039A "Κ" Greek Capital Letter Kappa is the uppercase version of the tenth letter in the Greek alphabet, corresponding to the English "K" and derived from the Phoenician letter kaph. In modern Greek, it represents the voiceless velar plosive sound, akin to the "k" in "kite," while in ancient Greek it held the same phonetic value. This character is commonly used in academic disciplines such as mathematics, physics, and statistics, where it often denotes a constant, a curvature, or a specific parameter. It also appears in technical notation for thermodynamic equilibrium constants, binding affinities, and as a symbol in linguistics for the velar plosive. The glyph itself resembles a vertical stroke with two diagonal arms extending from the top and middle of the right side, distinguishing it from the Latin "K" by its slightly more vertical proportions and open shape.
