Etymology: "Buoyages" is the plural of "buoyage," a collective noun for the markers that float on water to show sailors where channels, hazards, or moorings lie. The base word, "buoy," came into English from Middle Dutch or a related Low German source, and the "-age" ending is a French-derived suffix that English took from Old French, where it was used to form nouns for collections, charges, and costs connected to a thing. The combination is plainly a practical coinage rather than an old term with a dramatic backstory. English speakers attached "-age" to "buoy" to name the whole system of floating marks, much as "pilotage" names the business of guiding ships and "moorage" the fees for tying up at a dock. The pairing of a Germanic-origin noun with a French-derived suffix is typical of English vocabulary, where such hybrids are common.
