Root Explanation

Confidentiality is formed from "con-" (meaning together) and "fidere" (meaning to trust). The word refers to the quality of being trusted together with someone, implying that information is shared in a trusted manner.

Memory Tip

Think of sharing information 'together' ('con-') with someone you 'trust' ('fidere') — that's what confidentiality means.
