• Absorption — The physical or chemical process by which a substance (gas, liquid, or energy) enters the mass of another body; in clinical toxicology and pharmacokinetics, it represents the entry of a toxin or drug into the bloodstream through biological membranes.
• Accadân — Historical and archaic name of a stream and an old village located in Tulcea County, Dobrogea, Romania. The settlement was originally inhabited by a significant Turkish and Tatar community that withdrew after the 1877 Independence War, with the village later repopulated by Romanian families from Moldavia.
• Aerodynamic — Relating to aerodynamics, concerning the motion of air and gases relative to solid bodies; having a fluid and optimized geometric shape, specially designed to minimize the drag resistance opposed by air during movement. It is widely applied in the design of aircraft, high-speed vehicles, and high-performance sports equipment.
• Aerodynamic efficiency — The quality, property, or degree to which a solid object possesses an aerodynamic shape; the structural capacity of a vehicle's body or an aircraft's fuselage to pierce through air layers with minimal drag resistance. Although frequently used in automotive or commercial jargon, the refined technical term 'aerodynamics' is preferred in academic settings.
• Agricea — The name of a small watercourse (stream) or a valley located within the geographic area of Romania, carrying local hydrographic importance. It represents a specific rural hydronym, often used by local communities as a landmark for outlining agricultural properties or pastures.
• Alburus — The name of a small stream or river in Romania, as well as a local surname or secondary toponym found within the Carpathian geographical region.

• Upstream — The upper sector of a watercourse, located towards the source, relative to a given reference point; the direction opposite to the water flow. Often used in hydraulic engineering and ecology to describe the location of structures or phenomena situated upstream.
• Upstream — Upstream, toward the sources of a watercourse; in the direction opposite to the water flow. As a noun, it designates the upper reach of a river relative to a fixed point of observation. Figuratively or economically, it describes the initial phases within a supply chain or industrial process.
• Upstream — A regional adverbial form used in certain mountainous areas to indicate the direction towards the mountain crest, up the slope, or towards the headwaters of a river. It functions as an antonym for the terms 'avale' or 'ajos', being a spatial orientation element specific to shepherding and lumberjack communities.
• Andrabus — A rare toponym of local origin, representing the name of a minor watercourse or a geographical micro-region within the Eastern European hydrographic area. In the context of historical cartography, the term identifies a low landform or a dry valley, historically used as a boundary marker for rural properties or boyar estates.
• 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.
• Aoșa — The name of a small river or brook within the Romanian hydrographic network, located as a tributary in mountain or sub-Carpathian basins. This microtoponym reflects features of ancient folk speech in certain isolated rural areas where archaic water names were preserved.
• Little water — A diminutive and hypocoristic form of the noun 'apă' (water); a small river, a brook, a thin stream of running fresh water, or a small quantity of clear liquid collected in a vessel.
• Argeșel — The name of a river in southern Romania, a left tributary of the Dâmbovița River, which originates in the Făgăraș Mountains and flows through Argeș County. Structurally, the term represents a hydronymic diminutive form derived from the Argeș River, also identifying the local village of Argeșelu in the aforementioned county, a microregion historically recognized for its picturesque rural settlements and well-developed hydrographic network.
• Arghel — The name of a river (tributary of the Moldovița river) and a component village within the Moldovița commune, Suceava county, Romania, structurally located in the picturesque mountain landscape of the Bucovina Ridges. In a geographical and documentary sense, the locality is characterized by a community tightly linked to traditional wood logging, animal husbandry, and the preservation of ethnocultural elements specific to Hutsuls and Bucovinians.
• Arinoasa — A Romanian toponym designating watercourses or rural micro-toponyms (such as the Arinoasa stream), whose name derives directly from the abundant presence of alder trees on their banks.
• Arpașu Mic — A secondary watercourse, left tributary of the Arpașu Mare river or component of the Arpaș hydrographic basin on the northern slope of the Făgăraș Mountains, Sibiu County. Its narrow valley is defined by rugged terrain and a hydrological dynamic specific to mountain torrents, contributing directly to the total discharge of the local hydrographic network in southern Transylvania.
