noun / verb
hammer
HAM-ur/ˈhæmər/
A tool used to deliver forceful repeated blows.
The hammer has a steel striking head and curved claw on a wooden handle.

Etymology
Old English hamor already named the striking tool. A related Old Norse word meaning “stone, crag” suggests that the name may originally have referred to a tool with a stone head.
In context
hammer can be used for an infinite number of things, not just hammering a nail.
