Which term means to accept something as true?

The term that means to accept something as true is "credence." It denotes a belief in or acceptance of something as valid or genuine. In various contexts, credence can refer to the level of trust that one places in a claim, statement, or piece of information. When someone gives credence to an assertion, they are essentially acknowledging it as worthy of consideration or belief.

The other options do not convey the same meaning. For instance, "contravene" suggests opposing or violating a rule or law, and does not imply acceptance. "Purport" often refers to the appearance of being or intending something, but does not necessarily involve belief. "Delineate" means to describe or portray something precisely, which also does not pertain to belief or acceptance. Thus, "credence" is the term best aligned with the concept of accepting something as true.
