Control (noun) is the ability or power to direct, manage, or regulate something or someone. To control (verb) means to direct how something behaves or develops. Example: She has excellent control over her emotions.
What Does Control Mean?
Control entered English in the 15th century from the Anglo-French contreroule, meaning a duplicate register used to verify accounts — the idea being that you check one roll against another to ensure accuracy. This gave rise to the broader modern sense of regulation and authority over something.
The Latin root contra (against) combined with rotulus (a small wheel or roll) is also the ancestor of words such as controller, controllable, and the British spelling controlling. The original notion of double-checking evolved into the modern meaning of having power over a process or situation.
In contemporary English, control spans a very wide range of contexts: technology (remote control), psychology (self-control), business (quality control), and everyday emotion management (lose control, stay in control).

Usage Notes
- Noun + preposition: Use control of when referring to possession of authority (control of the company) and control over when emphasising dominance or influence (control over her emotions). Both are correct; control over is more common in personal or emotional contexts.
- Verb object: Control as a verb is transitive — it always takes a direct object: control the temperature, control your breathing. You cannot say control without specifying what is being controlled.
- Double consonant in British English: In British English, the final l is doubled before suffixes beginning with a vowel: controlled, controlling, controller. American English uses a single l: controlled (same), but controlling is identical in both varieties.
- Scientific register: In research and academic writing, a control (noun) refers to a baseline condition against which experimental results are measured. This is a specialist use that learners at C1+ should recognise.
- False friend warning: In several European languages, the cognate of control means simply "to check" or "to inspect". In English, control implies authority and power over something — closer to manage or regulate than to check.
