diffident

Definitions

dif- (apart, away) + fid (trust) + -ent (adj.) = 'trusting turned away.' You'd expect 'distrustful,' but the missing trust is trust in oneself — so diffident means shy, hesitant, lacking self-confidence. It's the quiet opposite of confident.

Why It Means This

The surprise is the direction of the missing trust. The prefix dif- (apart) suggests trust withdrawn, and you might guess it means suspicious of others. But historically the word settled on a lack of trust in oneself — hence shy and self-effacing, not wary. Confident and diffident share the same root with opposite prefixes: full self-trust vs self-trust pulled away.
