Picture a medieval speaker saying that someone was worthy of trust: confidence began as an assurance placed in another person, not merely a feeling in your own chest. Its Latin ancestor cōnfīdentia grew from con- and fīdō, so the original image was almost “trust made especially firm.” The same trust-root, traced by etymological sources to PIE *bheidh-, appears in faith and fidelity—and even in fiancé, historically someone to whom one has pledged faith. Around 1400, English inherited confidence through Middle English, probably by way of Old French, although a direct Latin route is also possible. By the 1590s it could mean a secret, because telling someone confidential information was itself an act of trust; confidence is therefore both the feeling that opens your mouth and the secret that comes out of it.
