- Adam-Klisi — A graphical, historical, or popular variant for the toponym 'Adamclisi', designating a commune in Constanța County, famous for the Roman archaeological complex hosting the Tropaeum Traiani triumphal monument, erected in the 2nd century. This structural name originates from the Turkish language, where 'Adam Kilisesi' literally means 'Man's Church' or 'Church of Adam', as Ottoman locals mistook the ancient monument's ruins for a church structure.
- Angkor — A monumental historical region in Cambodia, situated in the Siem Reap province, which served as the capital and structural nucleus of the Khmer Empire between the 9th and 15th centuries. This well-defined archaeological site, inscribed on the UNESCO World Heritage list, houses religious architectural structures of unique scale, such as the famous Hindu and Buddhist Angkor Wat complex, reflecting the pinnacle of Khmer civilization, advanced hydraulic irrigation systems, and highly complex sculptural art.
- Appia — The historical name of the famous Roman road 'Via Appia', nicknamed in antiquity 'Regina Viarum' (Queen of Roads), constructed starting in 312 BC by the censor Appius Claudius Caecus to connect Rome with Capua and later Brindisi.

- Arius — A geographical proper name borne by settlements or watercourses in the Romanian territory, most notably the Ariușd village in Covasna county, archaeologically renowned for the Neolithic site belonging to the Cucuteni-Ariușd culture.
