- Aegeus — Mythical king of Athens, son of Pandion II and father of the hero Theseus, recognized in Hellenic legends for founding early Athenian power structures. His name is permanently linked to the Aegean Sea, into whose waves he threw himself from the cliffs of the Acropolis due to a tragic misunderstanding, erroneously believing his son was killed by the Cretan Minotaur because the returning ship carried black sails.
- Aegisthus — A tragic figure in Greek mythology, the adulterous son of Thyestes and his own daughter Pelopia, born as an instrument of bloody vengeance within the cursed house of the Pelopidae. He is celebrated as the lover of Clytemnestra, with whom he plotted to assassinate King Agamemnon upon his return from the Trojan War, usurping the throne of Mycenae until he was slain by Orestes in an act of filial retribution.
- Aeonium domesticum — A scientific name often used for a popular horticultural hybrid (correctly known as Aichryson x domesticum), belonging to the same Crassulaceae family, characterized by small rosettes of velvety, slightly hairy leaves and thin, highly branched stems. It is an extremely widespread houseplant, valued for its adaptability to indoor conditions and its star-shaped yellow flowers.
- Aërangis biloba — A popular species of epiphytic orchid in the genus Aerangis, native to a wide range of tropical West and Central Africa. It is structurally recognized by its obovate leaves that feature an asymmetrically split tip forming two distinct lobes (bilobed), and by pendulous spikes bearing up to twenty star-like, white flowers with pale pink hues on their short spurs, heavily fragrant at night.
- Aerides — A genus of tropical epiphytic orchids in the family Orchidaceae, native to South and Southeast Asia (from India to the Philippines and New Guinea). They are structurally characterized by vigorous monopodial growth, thick and long aerial roots, and densely clustered pendulous inflorescences with spectacular, heavily fragrant flowers, typically white, pink, or purple, featuring a characteristic forward-pointing spur.
- Aërides cylindricum — A rare species of epiphytic orchid in the genus Aerides, family Orchidaceae, native to the mountainous regions of Southern India. It is structurally characterized by unique, terete, cylindrical leaves adapted to reduce water loss, and by short spikes bearing large, solitary or few-clustered flowers, which are white with pale pink or violet hues on the lip, heavily fragrant.
- Aërides falcatum — A remarkable ornamental species of epiphytic orchid in the family Orchidaceae, native to Southeast Asia (Thailand, Vietnam, Laos, Cambodia, and Myanmar). It is structurally characterized by robust monopodial growth, strap-like, rigid leaves slightly curved like a sickle (falcate), and long, pendulous inflorescences bearing numerous creamy-white flowers with spectacular bright pink-violet blotches on the tips and lip, heavily fragrant.
- Aërides odoratum — The type and highly popular species of tropical epiphytic orchid in the genus Aerides, family Orchidaceae, native to a wide range of South and Southeast Asia. It is structurally characterized by long and robust monopodial stems, strap-like fleshy leaves, and densely packed pendulous inflorescences bearing numerous white or creamy flowers with purple spots at the tips, renowned for their sweet and intense fragrance resembling lemon or jasmine.
- 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.
- Aerodynamics — A branch of fluid mechanics that studies the laws governing the motion of air or other gases, as well as the forces exerted by them on solid bodies in relative motion to them. This scientific field governs the design of aircraft, rockets, and terrestrial vehicles by optimizing lift and drag forces.
- 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.
- Airbrake — A mobile aerodynamic device (retractable lifting surface, flap, or spoiler) mounted on the wings or fuselage of an aircraft or space vehicle, designed to be deployed into the airflow in order to increase drag resistance and rapidly reduce movement speed.
- Aphareus — Proper noun of ancient Greek origin denoting a distinct historical or mythological figure. In Greek mythology, it refers to a legendary king of Messenia, father of Idas and Lynceus; in literary history, it indicates an Athenian orator and tragic poet of the 4th century BC, adopted son of Isocrates.
- Affection / Fondness — A noun with two primary meanings. Emotionally, it denotes a steady feeling of fondness, attachment, warmth, or love toward someone. Clinically, it refers to a pathological condition, disease, lesion, or functional disorder of an organ or biological system.
- Regional medicinal plant — A regional popular name attributed to a herbaceous plant or shrub with empirical medicinal properties or domestic utility, found in the spontaneous flora of certain rural areas in Romania. The term reflects the ethnobotanical richness of local dialects, being frequently used in traditional phytotherapy to alleviate various skin or digestive ailments.
- Permission — The act of permitting and its result; the granting of a permission, a consent, or a tolerance toward a certain state of affairs. It also represents the act of respite, clemency, or indulgence by which someone is offered a temporary delay or a postponement of a penalty, used as a rare variant in old texts or regional dialects.
- Agamemnon — A central character in Greek mythology and Homer's epic 'Iliad', legendary king of Mycenae and the supreme commander of the Achaean armies during the Trojan War. Son of Atreus and brother of Menelaus, his structural figure embodies absolute royal authority, but also the tragic pride that triggered the conflict with Achilles, being assassinated upon his return by his wife, Clytemnestra.
- Agathon — An ancient Greek tragic poet from Athens, a contemporary of Socrates and Euripides, famously known as the main character and host in Plato's celebrated dialogue, the 'Symposium'. His work, of which only very few fragments survive, introduced structural innovations into Hellenic tragedy, such as utilizing entirely fictional characters and plots instead of traditional mythology, as well as composing musical interludes independent of the play's main plot.
- Agavaceae — A taxonomic family of monocotyledonous angiosperm plants (Agavaceae), currently classified as a subfamily (Agavoideae) within the Asparagaceae family. It comprises perennial, xerophytic, or succulent plants, with leaves often arranged in basal rosettes and perfectly adapted to hot and dry climates, including famous economic and ornamental genera such as Agave, Yucca, and Sansevieria.
- Agave — The official taxonomic genus grouping numerous succulent plant species within the subfamily Agavoideae, family Asparagaceae. Members of this genus are renowned for their CAM metabolism which enables water conservation, their socio-economic importance in producing traditional distilled beverages (such as tequila and mezcal), and their major ecological distribution within New World arid biomes.
