Etymology
Origin of secure
First recorded in 1525–35; from Latin sēcūrus “carefree,” equivalent to sē- se- + cūr(a) “care” ( see cure) + -us, adjective suffix; cf. sure
Explanation
Secure means safe, protected. Your money is secure in a bank. Supportive friends and family make you feel secure. Secure can also be used as a verb. You secure the sails before you take out the sailboat, which means you tie them down. If you secure someone a ticket to a popular Broadway play, you've found them a hard-to-find seat. On an airplane, you're told that in the event you need an oxygen mask, you should secure yours — get it in place — before helping someone else. Almost all meanings contain the idea of safety: making sure things are right.
