Etymology: "Coastguard" is about as transparent as English compounds get: "coast" joined to "guard," with nothing hidden in either part. "Coast" comes from Old French "coste," meaning a slope or side, which passed into English and came to mean the land along the sea. "Guard" entered English from Old French "garde," a term for watching over or protecting, and it is a word with a long history of its own, related to "ward" and "warden." The compound describes exactly what it sounds like. Its first element places the work at the boundary where land meets water, and its second element names the job of watching over that boundary and the people on it. The word is therefore a straightforward description of a function rather than a metaphor or a name pulled from history. Because the word is so direct, its meaning has stayed close to its parts. A coastguard watches the shore, guards against threats arriving from the sea, and steps in when ships or swimmers run into trouble, which is simply what the two elements promise.
