Keeping under one's thumb is an idiomatic expression that refers to having firm control or dominance over someone or something. The phrase suggests the idea of keeping someone or something metaphorically suppressed or subjugated, just as one might hold a person or object under their thumb in a tight grip.
To keep someone under one's thumb implies asserting authority or power over them, often in a controlling or manipulative manner. It suggests that the person in power has significant influence and control over the actions, decisions, and behavior of the person or people being controlled. This influence can be exerted through various means, such as intimidation, coercion, or manipulation, resulting in the submissive party being unable to act independently or make decisions freely.
The expression is commonly used in contexts where one person has considerable dominance over another, typically in personal relationships, workplaces, or hierarchical structures. It can describe situations where someone exercises control over another's actions, thoughts, or choices, limiting their freedoms and autonomy.
Keeping someone under one's thumb can also imply a level of dependency or subservience, as the person being controlled may feel trapped or helpless in their situation. The phrase implies a power dynamic that is imbalanced, with one party having a disproportionate amount of control and authority over the other.
