Which word means to hinder or obstruct something?

The word "stymie" is often used to describe the act of hindering or obstructing progress, plans, or efforts. This term conveys a sense of creating a barrier that prevents someone from achieving their goals or completing a task. In various contexts, such as discussions about project management, problem-solving, or any situation where progress is impeded, "stymie" effectively captures the essence of obstruction.

In contrast, "transience" refers to the state of being temporary or short-lived, focusing on the fleeting nature of existence rather than obstruction. "Stupefy" means to shock or amaze someone, often to the point of rendering them unable to think or react clearly. "Superfluous" describes something that is unnecessary or excessive, implying surplus rather than obstruction. Thus, "stymie" accurately represents the concept of hindrance, making it the correct choice in this context.
