The original term in Amharic indicates a mountain fortress. Amba Geshen, for example, is a historically significant amba where members of royal families were kept under guard for their safety and to prevent their participation in plots against the sitting emperor. Other noted Ambas include Amba Aradam and Amba Alagi, sites of famous battles during the first and second Italo-Ethiopian Wars. In Tigrinya, the term is "Emba" (also spelled "Imba").
