The “C” on the C button doesn’t mean anything

It seems so obvious to me that the only reason the C button is called that is because Nintendo had already named other buttons on older controllers that way. The Nintendo 64 controller had the C buttons, the GameCube controller had the C-stick, and even the Wii Nunchuck had a C button. Many people speculate about theories saying the C might stand for “cast,” “capture,” “chat,” or other similar things. I’m convinced that the C isn’t directly tied to the button’s function. It’s just that Nintendo has a “tradition” of naming buttons “C.”
