A positive declaration intended to give confidence; a promise or guarantee. Confidence or certainty in one's abilities.
From Old French asseurance, from assurer meaning 'to make sure.' Ultimately from Latin ad- (to) + securus (secure). The word entered English in the 14th century.
Assurance beautifully bridges the external (promises from others) and internal (self-confidence) meanings of security - we need both others' assurances and self-assurance to navigate uncertainty effectively.
