• Adige — The second longest river in Italy (after the Po), originating in the Rhaetian Alps near the borders with Austria and Switzerland, and flowing for over 400 kilometers through the Trentino-Alto Adige and Veneto regions before emptying into the Adriatic Sea. This structural hydrological entity traverses major historical cities such as Verona, playing a crucial role in irrigation, hydropower, and the economic geography of Northern Italy.
• Alazeia — A major river located in northeastern Siberia, within the Sakha Republic (Yakutia), Russian Federation; a watercourse with a length of approximately 1,590 km, which rises from the Alazeia Plateau and structurally flows through the East Siberian Lowland in a catchment basin marked by thousands of lakes, emptying into the East Siberian Sea (Arctic Ocean). This river is characterized by an extreme hydrological regime, remaining frozen from late September until early June, serving as a vital ecological artery for the subarctic tundra and forest-tundra zones.
• Allahabad — A highly important historical city located in the northern Indian state of Uttar Pradesh, officially renamed Prayagraj in 2018. The city is famous in universal culture as a sacred Hindu pilgrimage site due to its geographical position at the 'Triveni Sangam', the confluence point of the holy rivers Ganges and Yamuna, along with the mythical underground river Sarasvati, hosting the gigantic Kumbh Mela festival.
• Alzette — A medium-sized river in Western Europe, approximately 73 kilometers long, which rises in France and flows primarily through the Grand Duchy of Luxembourg, crossing its capital city and emptying into the Sauer River. This watercourse represents a major hydrographic and landscape structural axis for the region, renowned for the deep valley it carves into Luxembourg sandstone and for the historical fortifications built along its banks in Luxembourg City.
• Yalu River — The official Korean name (Amnok-kang / Yalu) of the border river located on the natural frontier between China and North Korea. Having a length of approximately 790 kilometers, its watercourse originates from the sacred Paektu Mountain and empties into the Korea Bay, representing a point of major geopolitical, historical, and strategic importance in East Asia.
• Riverside anemone — A scientific synonymous name for Eriocapitella rivularis, a perennial herbaceous plant in the family Ranunculaceae, native to a wide range across Asia (Himalayas, India, China, Nepal). This vigorous garden plant prefers stream banks, floodplains, and damp meadows, standing out due to its tall, branched stems that bear numerous immaculate white flowers, whose sepals have a blue-indigo or violet reverse, highlighting the azure stamens in the center.
• Asprete fish — A regional and popular name used in certain hydrographic basins for the asprete (Romanichthys valsanicola) or for related small freshwater fish species in the Percidae family; a rare fish, considered a monument of nature, adapted to fast mountain streams with rocky bottoms, where it lives hidden under rocks. The term functions as an archaic indicator in local fishing dialects of the Carpathian zone.
• Asprete fish — A rare regional variant for the asprete (Romanichthys valsanicola) or for other small mountain fish species in the Percidae family; an endemic Carpathian fish with very rough and rigid scales, adapted to fast-flowing streams with rocky bottoms. The term is used exclusively in certain sub-mountainous rural communities as a descriptive popular name based on the texture of the fish's protective coating.
• Female asprete — A feminine form or rare regional variant popularly used to denote the female of the asprete fish (Romanichthys valsanicola) or other related mountain fish varieties in the Percidae family; the term is strictly localized in the villages along the mountain river valleys of the Carpathians, making direct reference to the structural roughness of the species' characteristic ctenoid scales.
• Atelcuzu — A historical name (derived from Byzantine sources, specifically from Emperor Constantine VII Porphyrogenitus' work as 'Etelköz') denoting the geographical region temporarily inhabited by Hungarian tribes in the 9th century, prior to their definitive settlement in the Pannonian Basin. The territory, literally translated as 'Between rivers' or 'The land between rivers', was located north of the Black Sea, likely spanning between the Dnieper, Dniester, Prut, and Siret rivers, partially covering areas of eastern Romania and Moldova.
• Avon — An international proper name with multiple applications. In a global economic context, it designates a leading American multinational cosmetics and personal care company, historically recognized for its direct selling model. In a geographical context, it represents the name of several rivers and counties in the United Kingdom (such as Stratford-upon-Avon, the birthplace of William Shakespeare), the hydronym originating from the Old Welsh word 'afon', which literally means 'river'.
