- Unruly — Unruly, bad-tempered, quick to anger, and difficult to control or tame (of people or horses); (of terrain, roads, or slopes) steep, precipitous, rugged, rocky, and difficult to access; (regional, of colors or visual appearance) striking, variegated, non-uniform, or spotted, usually having white spots on a dark background.
- Abrașan grape — (Regional) A variety of Romanian grapes with white-greenish berries, grown locally; (by extension) a horse of a specific breed, often characterized as being bad-tempered, high-spirited, or having a variegated appearance.
- Abraxas — A mystical word, symbolic formula, and supreme deity in the cosmology of certain Gnostic sects (especially the followers of Basilides), representing the Supreme Divinity, the Primordial Source, or the ruler of the 365 heavens; (history of religions) a cabalistic word whose Greek letters, when added according to Hellenic numerology (isopsephy), total exactly the value of 365, corresponding to the number of days in a solar year; symbolically represented as a hybrid figure with a rooster's head, a human body, and legs formed by serpents.
- Abrastol — The calcium salt of sulfo-beta-naphthol, used historically in the food and winemaking industries as an antiseptic, preservative, and stabilizing agent for fermented beverages; a chemical compound from the naphthol derivatives class later banned by modern sanitary laws due to its high toxic potential on the organism.
- To abrade — (Technical, rare) To perform an abrasion operation; cutting or smoothing a rigid surface through friction with abrasive materials; to grind or polish industrially.
- Abrasion — A complex process of mechanical wearing down, erosion, grinding, or polishing of a solid surface (rocks, metals, industrial materials) through repeated friction with hard particles or abrasive bodies; (in geology) the destructive erosive action on sea or large lake shores exerted by the violent movement of waves and transported debris; (in medicine/dentistry) progressive pathological loss of hard dental substance or skin tissue (superficial scratch, graze) caused by external mechanical frictional factors.
- Abrasive — A natural or artificial product or material (such as diamond, corundum, carborundum, or sand) composed of hard granules used through friction, wear, or impact to cut, polish, clean, or smooth metallic, wooden, or mineral surfaces; (adjectival, literal) possessing a rough structure capable of wearing down or eroding through friction; (adjectival, figurative) a communication style, behavior, or individual character marked by harshness, aggressiveness, verbal roughness, lack of tact, and a tendency to generate interpersonal conflicts or tensions.
- Almandine — A silicate mineral representing the most widespread and common species of the garnet group, featuring a characteristic deep red, purplish-red, reddish-brown, or black color, containing iron and aluminum. It crystallizes in the cubic system, has a vitreous luster, and high hardness (7-7.5 on the Mohs scale), with its transparent varieties utilized since antiquity as semi-precious gemstones in jewelry and opaque ones as industrial abrasives.
- Aloxite — A commercial or technical designation attributed to a type of artificial corundum (crystallized aluminum oxide), obtained by melting bauxite in specialized electric furnaces. This abrasive material stands out structurally due to its extremely high hardness and thermal resistance, widely utilized in industry for manufacturing grinding wheels, sandpaper, and cutting discs for hard metals.
- Anemoclastics — Clastic rocks, mineral fragments, or sedimentary deposits fragmented, crushed, and structurally shaped by the mechanical action of erosion, abrasion, or transport carried out by the wind (aeolian processes). As an adjective, it describes geological structures or debris formed via wind deflation and corrasion.
- Aeolian corrasion — A geomorphological process of disintegration, fragmentation, and structural destruction of rocks under the direct and prolonged action of wind laden with abrasive sand or dust particles; natural aeolian corrasion or sandblasting.
- Extremely rough — Very rough, excessively rugged, coarse, or sharp; an augmentative adjective used in popular speech to describe an object, a material, or a tool with highly pronounced roughness; it can also denote a type of fish or a rudimentary tool used for cleaning surfaces through abrasive rubbing.
