• Avaș — An archaic regionalism used in certain areas of northwestern Romania to describe a wooded land, a deep clearing, a narrow valley, or a secluded, shaded place; the term also has a strong toponymic value, being closely linked to the Oaș Country (the historical name originates from a similar etymological root). As an adjective, in ancient local dialects, it could express the idea of a hidden, sheltered, or wild location.
• Bac Bo — A geographical and historical name used to designate the northern region of Vietnam, historically known in the West as Tonkin. This area, centered on the fertile delta of the Red River, represents the cradle of Vietnamese civilization and includes the capital Hanoi; in a modern sense, the term is used in administration, geopolitics, and tourism to describe the northern Vietnamese provinces.
