self-doubt
UK: ˌself ˈdaʊt | US: ˌself ˈdaʊt
n. lack of confidence in one's own abilities or judgment
The word "self-doubt" combines "self," derived from Old English "self" (meaning "one's own person"), and "doubt," from Old French "douter" (meaning "to fear or hesitate"), which traces back to Latin "dubitare" (to waver or hesitate). The compound emerged in English to describe the internal struggle of questioning one's own worth or decisions, reflecting a blend of introspection ("self") and uncertainty ("doubt").
