confidencial
/konfidenˈθjal/ · B1 · adj
confidential (kept, or meant to be kept, in secret)
🤫🔒 Looks like English confidential: shared only with those you confide in
From Latin confidentia, trust, built from con- (with) plus fidere (to trust), the same root as fidelity. Something confidencial is told only to people you trust. The final -cial is said thyal in Spain, so it sounds like con-fee-den-THYAL.
