Etymology

The word "diffident" originates from Latin diffidere ("to distrust"), combining dis- (apart, away) and fidere (to trust). The morpheme fid (from Latin fides, meaning "faith" or "trust") appears in related words like "confidence" (full trust) and "infidelity" (lack of trust). Over time, "diffident" evolved to describe someone who withdraws (dif-) from trust (fid) in themselves, hence its modern meaning of shyness or self-doubt.
