• Antiworld — A hypothetical world, parallel universe, or symmetrical cosmic region structurally composed entirely of antimatter, where atoms are formed by antiprotons, antineutrons, and positrons. In a theoretical sense, a direct structural collision between our world and an antiworld would generate a process of total annihilation, releasing an immense amount of energy in the form of gamma rays.
• Antitropic — Exhibiting inverse symmetry, situated in direct structural opposition, or having physical and geometric properties oriented in the opposite direction relative to a reference element. In anatomy, it describes paired organs or structures facing each other in opposite planes; in crystallography, it refers to symmetrically inverted crystalline axes or faces.
• Anti-universe — A hypothetical universe composed entirely of antimatter (antiparticles such as antiprotons, antineutrons, and positrons), representing an inverted physical and structural duplicate of our material universe. In advanced quantum mechanics theories and science fiction literature, a potential direct contact between our universe and this anti-universe would instantly lead to total annihilation, converting the entire mass into pure energy.
• Diaphragm girder — A secondary horizontal beam, rigid connecting piece, or structural stiffening element mounted transversally between two parallel main girders, aiming to maintain their distance constant, prevent their twisting or buckling, and uniformly distribute gravitational or dynamic loads. This element is essential in the construction of steel bridges, viaducts, and complex roof frameworks.
• Archilochian verse — A reference to the famous Greek lyric poet Archilochus of Paros or, in a structural-metric sense, the name of verses or stanzas composed of specific combinations of dactyls and trochees invented or popularized by him in ancient satire. In literary terminology, an archiloc denotes an asymmetrical, vigorous rhythmic structure, often used to convey polemical, ironic, or incisive messages.
• Arda — A proper name designating a major river in the Balkan Peninsula, a tributary of the Maritsa, rising in the Rhodope Mountains (Bulgaria) and flowing through northeastern Greece and a section of Turkey. In the context of J.R.R. Tolkien's high-fantasy legendarium, the term represents the mystical name of the entire created Earth, including continents and seas, configured as the structural realm for the history of Elves and Men.
• Arol coin side — An archaic and regional Romanian term attested in southern Moldova denoting the obverse (face) of a coin or medal, traditionally featuring an emblem like an eagle. By extension, it signifies an old rural gambling game similar to heads or tails.
• Arolă — A regional feminine variant and historically attested form of the noun 'arol', used identically to denote the obverse side of a coin or the traditional coin-flipping game.
• Asclepiad — A verse used in ancient Greek and Latin metrics, composed of a spondee, two or three dactyls, and a trochee, or characterized by the presence of choriambs, attributed to the poet Asclepiades of Samos. As an adjective, it describes a stanza, a poem, or a rhythmic structure organized according to these rigorous writing rules.
• Astrophic — Not organized into stanzas; a term used in literary theory and poetics to describe a poem, lyrical composition, or verse text that flows continuously without structural division into defined strophic units. This compositional technique provides the text with a distinct narrative or discursive fluidity, characteristic of certain modern literary movements or grand-scale poems in classical epics.
• Astronomy — A fundamental and natural science that deals with the study, observation, measurement, and physico-mathematical interpretation of celestial bodies (stars, planets, satellites, comets, asteroids, galaxies), cosmic structures, and the universe as a whole. This discipline investigates the origin, evolution, chemical composition, and motion dynamics of matter and energy in extra-atmospheric space, being one of the oldest branches of human knowledge.
• Obverse — The obverse or principal face of a coin, medal, seal, or decoration, usually bearing the effigy of the issuer, the state coat of arms, the ruler's name, or the primary symbolic motif; popularly known as 'heads' in contrast to the reverse ('tails'). As an adjective, in technical or specialized usage, it describes the element facing forward or the side directly presented to view during the minting or printing process.
• Backhand — A technical stroke executed in racket sports (tennis, table tennis, badminton) played with the back of the hand facing the direction of the ball's trajectory. This structural maneuver requires specific body positioning and shoulder rotation, and it can be performed either single-handed or with both hands to ensure superior control and increased ball speed.
