Etymology: "Hammerstone" is a plain compound: "hammer" joined to "stone," the two words simply placed side by side to name a stone used as a hammer. The name describes the function rather than the material, which matters here because archaeologists use it for stones that were never shaped into tools at all. A hammerstone is typically a natural cobble, often quartz or flint, whose rounded ends show battering from repeated blows. The word's real interest lies in what it reveals about how the objects were identified. Early prehistorians, working from the battered stones they found alongside flint blades and cores, needed a name that said what the stone did, and "hammer" plus "stone" did that without any assumption about the material. The compound is transparent to any English speaker, which is why it has stayed in use in archaeological writing for stone tools.
