confidentiality
UK: ˌkɒnfɪˌdenʃiˈæləti | US: ˌkɑːnfɪˌdenʃiˈæləti
n. the state of keeping information private or secret
n. the ethical or legal obligation to protect sensitive data
The word "confidentiality" traces back to Latin roots. The prefix "con-" (together) combines with "fidere" (to trust), forming "confidere" (to trust fully). The suffix "-ential" transforms it into an adjective ("confidential"), and "-ity" nominalizes it, creating the abstract concept of secrecy or privacy. The progression reflects trust-based secrecy—a shared understanding of protected information.
