Origin & History of “hammer”

Hammer is part of a widespread Germanic word-family, including also German and Danish hammer, Dutch hamer, and Swedish hammar. The ancestor of the Scandinavian forms, Old Norse hamarr, meant ‘stone crag’ as well as ‘hammer’. this and possible connections with the standard words for ‘stone, rock’ in the Indo-Iranian and Balto-Slavonic language groups (such as Sanskrit açman and Russian kamen’) suggest that hammer originally denoted some sort of tool with a stone head.
