25 is one of the letters used in the wrare language, of the Canacanatranancona. 25 makes the same sound, as the letter "L" in the English Language, but with a stronger accent.
25 was first used in 1924, by the inventor of the Canacanatrananconan Language, Wie Am I. Onn Mie Hed. 25 has been used ever since. But Propositions have been made quite a few times in the history of the Canacanatranancona, to outlaw the letter 25. But the majority have always voted No, due to language loving.
