Etymology

From secure + -ity, from Middle English securite, from Middle French securité (modern sécurité), from Latin sēcūritās, from Latin sēcūrus (“safe, secure”), from sē- (“without”) + cūra (“care”); see cure. Similar to Latin sine cūrā (“without care, carefree”), which led to English sinecure. Doublet of surety.
