The 10th Greek Letter: Kappa

A Symbol of Change and Transformation

Kappa, the tenth letter of the Greek alphabet, holds a deep significance in Greek culture and beyond. Its symbolic meanings have evolved over centuries, reflecting the dynamic nature of language and the human experience.

Origins and Etymology

The origin of Kappa lies in the Phoenician letter Kaph, which represented the sound “k.” As the Greek language developed, Kappa adopted this sound and became an integral part of the Greek alphabet.

In ancient Greece, Kappa was associated with the god Poseidon, ruler of the seas. This connection likely stemmed from the letter's resemblance to a wave or cresting wave. Kappa also symbolized change and transformation, as it stood for the transition between the “old” and the “new.”
