Etymology

Origin of protect

First recorded in 1520–30; from Latin prōtēctus “covered in front,” past participle of prōtegere “to cover in front,” equivalent to prō- pro- ¹ + tegere “to cover” (akin to toga, thatch )

Explanation

Whether it’s your reputation or your jewelry, when you protect something you keep it safe from anything that might threaten or harm it. The word protect came into English by way of the Latin verb protegere, a combination of pro- meaning “in front,” and tegere, meaning “to cover.” When you protect something, in a way you’re covering it or shielding it from harm. Often the word is used in the sense of protecting something, like a valued item or a person, but you can also protect against something. For example, you might get a flu shot to protect against the flu virus.
