Etymology
It is formed from Old French en- + seur (“sure, safe”), a verb made on the adjective.[1][3][4] The adjective is from Latin sēcūrus (“free from care”),[5] itself made of sē- (“without”) and cūra (“care”).[6][5] The AND refers the verb to the FEW's article on the Latin adjective, and Tobler–Lommatzsch sets it beside the parallel asseurer.[1][3] Etymonline thinks the verb was probably influenced by that parallel formation.[4]
Earliest recorded meaning
The word is Anglo-Norman: the AND's first citation is of 1271–72.[1] Greimas dates the word to 1304 in the Year Books of the English courts, with the sense "to assure",[7] and Godefroy quotes the same law reports: Pur enseurer l'estat Adam "to secure Adam's estate".[2]
Semantic evolution
From making someone or something safe the verb passed to giving a pledge or guarantee, and reflexively to feeling secure or banding together for safety; the past participle served as an adjective, "safe, protected" and "assured, certain of".[1] Tobler–Lommatzsch has no quotation of its own and refers to Godefroy.[3] It lived on in English as ensure and its spelling variant insure.[8][4]

Anglo-Norman
The AND heads the verb enseurer, with the spelling ensurer, and dates its first citation to 1271–72.[1] Middle English took it as ensuren, also spelled enseuren, "to assure (someone that something is true)", often in the verse filler "I you ensure"; the MED derives it from the Old French verb.[8] Its English descendants are ensure, late 14th century, and insure, a mid-15th-century spelling variant that later took the commercial sense of insurance.[4]
