Etymology: Grousers are the metal cleats or bars bolted to the treads of tracked vehicles and to the soles of some boots and snow equipment, and the name comes from the verb "grouse," not from the bird. The plural form simply makes "grouser" the agent-style noun for the thing that does the gripping. The verb "grouse" is itself of uncertain origin, which leaves the deeper history of the sense unclear. The suffix "-er" is the familiar English ending that turns a verb into a noun for a person or device, as in "lever" or "hammer." Its origin lies in Old English "-ere," which traces back through Latin "-arius" to a Proto-Germanic form, and it gave English a steady supply of tool names. Attaching it to "grouse" produced a term for whatever grips or bites into a surface.
