Which term means to accept something as true without proof?

The term that means to accept something as true without proof is "believe." When someone believes something, they accept it as true or probable without needing concrete evidence or verification. This process often relies on personal conviction, experience, or intuition rather than empirical data or rational analysis. Belief is a fundamental aspect of human cognition and can underpin various decisions and actions individuals make based on their understanding of the world around them.

While "assert," "confirm," and "trust" may involve elements related to belief, they do not fit the specific definition of accepting something as true without proof. An assertion typically involves stating something confidently, often seeking to persuade others of its truth, while confirmation requires some level of evidence or validation to support the claim. Trust, on the other hand, involves reliance on the integrity, strength, or ability of someone or something, which also implies a level of proof or experience that justifies that reliance.

In summary, to "believe" is to take something as true without the necessity of proof, making it the most accurate choice in this context.
