Origin of sure

  • Middle English from Old French safe from Latin sēcūrus secure

    From American Heritage Dictionary of the English Language, 5th Edition

  • From Middle English sure, sur, from Middle French sur, from Old French seür, from Latin sÄ“cÅ«rus (“secure", literally “carefree"), from se (“apart") + cura (“care") (compare Old English orsorg (“carefree"), from or- (“without") + sorg (“care")). See cure. Displaced native Middle English wis, iwis (“certain, sure") (from Old English Ä¡ewis, Ä¡ewiss (“certain, sure")), Middle English siker (“sure, secure") (from Old English sicor (“secure, sure")).
