The name KDE was intended as a word play on the existing Common Desktop Environment, available for Unix systems. It was supposed to be an intuitively easy-to-use desktop computer environment. The K was originally suggested to stand for “Kool”, but it was quickly decided that the K should stand for nothing in particular – thus the KDE acronym expanded to “K Desktop Environment”. Additionally, one of the tips in certain versions of KDE 3 incorrectly states that the K currently is just meant to be the letter before L in the Latin alphabet, the first letter in the word Linux (which is where KDE is usually run).
