n. a person who protects or watches over something or someone
vt. to protect or keep safe from harm or danger

The word "guard" originates from the Old French garder, meaning "to protect or keep watch," which itself derives from the Frankish wardōn (a Germanic root meaning "to watch or defend"). The term entered Middle English as garden or warden, eventually settling into its modern spelling and meaning. The evolution reflects a shift from Germanic to Romance influence, retaining the core idea of vigilance and protection.
