Which word means to make something known to others?

The word that means to make something known to others is "apprise." When you apprise someone, you inform or notify them about something, typically providing them with important or relevant information. This term emphasizes the act of conveying knowledge or awareness to another person, which is central to communication in various contexts, whether in professional settings or everyday conversations.

In contrast, other choices do not convey this exact meaning. For instance, "broach" refers to mentioning or introducing a topic for discussion, which implies a conversation starter but does not necessarily encompass the broader notion of notifying or informing someone. "Antithetical" describes something that is opposite or contrary, while "aspersion" refers to the act of making damaging or slanderous remarks about someone, which is unrelated to the idea of sharing knowledge or information. Thus, "apprise" is the clear choice that accurately reflects the act of informing others.
