• Actinium variant — An archaic graphic form or transliteration used in 19th-century science textbooks for the chemical element actinium; a Latinized literary name designating substances or compounds with specific radiant structural properties. In modern terminology, the term has been completely replaced by internationally standardized forms.
• Amplexion — The act or state of embracing, surrounding, or structurally clasping; in old or comparative anatomical and medical terminology, it designates the circular encompassing of an organ by a neighboring muscular or vascular formation. This term conveys a conceptual nuance of close and intimate anatomical fixation between two tissue elements.
• Amythaonius — A Latin possessive adjective derived from the name Amythaon, meaning 'amythaonic', 'of Amythaon', or 'descended from Amythaon'. It is used in classical Greco-Roman poetry (for instance, in the works of Virgil or Ovid) as an elegant patronymic epithet to describe his son, the prophet Melampus (Melampus Amythaonius).
• Anti-Latinism — A political doctrine, ideological movement, or xenophobic attitude directed against Latin peoples, their culture, language, or historical heritage; a rejection of or prejudice toward the Neo-Latin or Mediterranean identity.

• Arabicus — A Latin term meaning 'Arabic' or 'originating from Arabia', currently utilized in the international nomenclature of biological sciences to designate plant or animal species native to the Arabian Peninsula. In historical or Christian theological texts, the word designates linguistic elements or manuscripts belonging to the Semitic cultural area, serving as a clear geographical and typological provenance marker in paleographic studies.
• Arachnoides — A term of Greco-Latin origin meaning resembling a spiders web, utilized in the international nomenclature of biological sciences as a specific epithet for various species or as an archaic variant for meningeal structures. In botanical taxonomy, it designates plants that exhibit fine, interwoven, and delicate hairs on leaves, stems, or rhizomes, creating a characteristic reticular appearance.
• Armoricum — Neuter proper form borrowed directly from Latin, used in historical sources and ancient cartography to designate the 'Armorican Sea' (Mare Armoricum) or territorial elements adjacent to the Brittany peninsula. Retained in academic and epigraphic studies.
• Asinus — The scientific Latin name for the donkey or ass (Equus asinus), a domestic mammal belonging to the equidae family; widely used in high-precision zoological taxonomy. In a cultural and literary sense, the term appears in famous Latin phrases or ancient medieval treatises to portray the animal's traits or to reference structural ignorance or stubbornness.
• Golden — Feminine singular form of the Latin adjective 'aureus' (golden, made of gold), widely utilized in biological binomial nomenclature as a specific epithet to indicate species of plants, fungi, or animals characterized by a brilliant golden-yellow coloration or distinct metallic reflections.
• Gold-variegated — Feminine singular form of a compound adjective used in botanical and horticultural binomial nomenclature to describe a cultivar or plant variety whose leaves are variegated, mottled, or striped with spots of an intense golden-yellow hue.
• Aureus — Latin taxonomic adjective meaning 'golden', used as a specific epithet in binomial nomenclature (famous for Staphylococcus aureus, named after the yellow color of its colonies on agar plates).

• Auxilium — A Latin term representing the original concept of help, assistance, or military alliance; in the Roman Empire, it denoted non-citizen auxiliary troops (auxilia), while in feudalism, it represented the obligation of military and financial assistance that a vassal owed to his lord (auxilium et consilium).
• Avis — A term borrowed directly from Latin (where it means 'bird'), used in old Romanian, archaic legal texts, or scientific ornithological works to designate a bird or a winged creature. Additionally, this etymological root forms the basis of many modern aviation and aeronautical neologisms (such as 'avion' or 'aviator'), being preserved as a reference element in classical taxonomic classifications.
• Azureum — A term of Latin origin used in international scientific nomenclature (botany, zoology, microbiology) as a specific epithet to designate species of plants, insects, or microorganisms that display a characteristic azure-blue coloration. In a structural sense, the word serves as a morphological indicator in taxonomy for the visual identification of specimens.
