Morphology

confidence = confide (opaque) = confide + ence

The word is formally built with the suffix -ence, but the statistical meaning is a specialized extension from the idea of trust or certainty and is not directly predictable from the base word for most learners.

Etymology

Confidence comes from the Latin parts con- ('with') and fidere ('to trust'), the same root as confide. In science and statistics this idea of 'trust' became a number, so a confidence score shows how much 'certainty' or trust we have in a result.
