What does diffidence mean?
Diffidence is the quality of being shy, reserved, or hesitant because one lacks confidence in oneself. A diffident person tends to hold back in social or professional situations, speak quietly, downplay their own abilities, or avoid asserting opinions — not out of arrogance or indifference, but out of self-doubt or excessive modesty. The word is formal in register and appears most often in writing: profiles of reticent public figures, descriptions of awkward first meetings, or accounts of talented people who underestimate themselves. Importantly, diffidence is not the same as indifference, which means lack of concern; nor is it mere politeness. It sits on the opposite end of the scale from confidence and assertiveness, yet it often attracts sympathy rather than criticism, since it suggests humility rather than fault. Knowing the word allows a precise distinction between someone who does not care to speak and someone who would like to but cannot quite dare.
nounDiffidence is shyness or modesty that arises from a lack of self-confidence; a hesitant, self-doubting manner in dealing with others.

Etymology of diffidence
Diffidence comes from the Latin verb diffidere, meaning 'to mistrust or lack confidence', formed from dis- ('away from') and fidere ('to trust'), the same root that gives us confidence, fidelity, and confide. English adopted the noun in the late sixteenth or early seventeenth century via the adjective diffident, which originally could mean 'distrustful of others' before narrowing to mean 'lacking self-confidence'. Its Romance cousins include French défiance and Italian diffidenza, which retain the older sense of distrust.
