Use the word confidant when you want to refer to someone who is entrusted with personal information and expected to keep it private. It typically indicates a relationship based on trust and discretion, often used to relate to the closest circle of friends or advisors.

The word confident is used to describe either a sureness about handling something, such as a task or social situation, or a certainty of opinion. Expressing confidence can relate to one's own abilities or the belief in someone else's capabilities.

While confidant and confident sound alike, their meanings are distinct. A confidant is someone you trust with your secrets, serving a noun in the English language. In contrast, confident describes an attitude of self-assurance or belief in someone or something, functioning as an adjective. Remember to use confidant when speaking about trust and discreet relationships and confident when describing certainty and self-reliance.
