Etymology

Origin of protection

First recorded in 1275–1325; Middle English proteccio(u)n, from Late Latin prōtēctiōn-, stem of prōtēctiō “shelter,” literally, “a covering in front”; equivalent to protect + -ion

Explanation

Protection refers to keeping something or someone safe. Through protection, we shelter and defend things. Since protecting is to shelter from harm, protection is the act of doing so. Children are under the protection of their parents, who keep them safe. The Secret Service is responsible for the protection of the President. Many famous people hire bodyguards, who offer protection. A security guard offers protection to a bank or store. Also, a house gives you protection from the weather. Valuable things and vulnerable people need the most protection. Protection keeps things and people safe.
