The word "control" has Latin roots as well. It is derived from the Latin word "contrarotulum", which refers to a "counter-roll" or a register that was used to verify accounts in medieval times. Ultimately, it comes from the Latin word "contrarotulus", where "contra" means "against" and "rotulus" means "roll" or "scroll".
The combination "gain control" likely emerged from the idea of acquiring or obtaining dominion or authority over something, particularly in terms of power, influence, or management.
