Which word means to demand something forcefully?

The term "insist" is used to describe a situation where someone demands something forcefully, showing a strong conviction about their request or belief. When you insist, you are not merely asking or requesting something lightly; instead, you are making it clear that you expect compliance or recognition of the validity of your demand. This forcefulness often implies a sense of urgency or importance associated with the request.

In contrast, other terms like "request" and "ask" generally imply a more polite or casual manner of seeking something, without the same level of forceful demand. "Command," while also conveying a sense of authority, can imply a more formalized structure or commands given in a military context, which is different from the personal forcefulness implied by insisting. Therefore, "insist" best captures the meaning of demanding something forcefully.
