The word "control" originates from the Latin word "contrōlāre", which means "to check, verify, or regulate". It stems from the Latin words "contrā", meaning "against", and "rōlla", meaning "roll". The concept of control involves having power over something and ensuring that it follows a predetermined course, similar to rolling against or checking its progress.
The term "button" has a different etymology. It comes from the old French word "bouton", which means "a bud, a knob". This French word was derived from the Latin word "botōnem", a variation of "botulus", meaning "a round swelling" or "sausage". The term "button" was eventually used to refer to any small, rounded object that could be pressed.
