(assure)
guarantee certainty
Etymology
'assure' originates from Old French, specifically the word 'asseurer', where the prefix 'a-' (from Latin 'ad-') meant 'to' and the root comes from Latin 'securus' meaning 'secure' or 'free from care'.
'assure' changed from Old French 'asseurer' and Middle English 'assuren' and eventually became the modern English word 'assure'.
Initially, it meant 'to make secure or free from care', and over time it evolved into its current senses of 'to make someone confident' and 'to guarantee or ensure something'.
