A pneumatic stapler that drives nails faster than your eyes can blink, shingle by shingle.

means A power tool—usually air-driven—that rapidly hammers nails to fasten shingles and other roofing materials to a roof deck.

from A plain compound of trade English. 'Roof' descends from Old English 'hrof,' meaning the top covering of a building, while 'nail' comes from Old English 'naegel,' a cousin of the German 'Nagel,' both reaching back to a Proto-Germanic root for a peg or claw. 'Nailer' adds the agent suffix '-er'—literally 'a thing that nails'—a workshop habit of naming tools by what they do (think of the planer, the router, the sander). The full phrase is a 20th-century arrival, born alongside the pneumatic nail gun, when the old roofer's hand-hammer gained an air hose and a trigger.
