Etymology

Origin of protector

1325–75; < Late Latin ( protect, -tor ); replacing Middle English protectour < Middle French

Explanation

A protector is someone who takes care of you. In most families, part of the parents' job is to be their children's protectors. A museum guard is a protector of valuable artworks, and a Great Pyrenees dog might work as the protector of a flock of sheep, barking at predators. You can tell from the word protector that it's all about protecting, or keeping safe from harm. In Latin, protect means "covered in front," from the verb protegere and its roots pro-, "in front" and tegere, "to cover."
