History
Etymology
Borrowed from Latin sēcūrus (“of persons, free from care, quiet, easy; in a bad sense, careless, reckless; of things, tranquil, also free from danger, safe, secure”), from sē- (“without”) + cūra (“care”); see cure. Doublet of sure and the now obsolete or dialectal sicker (“certain, safe”).
