controlar
/kontɾoˈlaɾ/ · A2 · verb
to control, to rein in
🎛️ controlar = control + -ar: the English word with a Spanish verb ending
Same root as English control, from French contrôle (contre-rôle, a duplicate register used to verify accounts). That checking origin explains why controlar also means to monitor or verify, not just to rein in.
