• Abducens nerve — An anatomical and clinical term used to denote the sixth cranial nerve (abducens nerve or lateral rectus nerve), which exclusively innervates the lateral rectus muscle of the eye. In neurological semiology and clinical psychiatry, paralysis or impairment of the abducens nerve causes convergent strabism and diplopia (double vision), being a crucial indicator for diagnosing intracranial hypertension, brainstem tumors, or skull base fractures, phenomena often accompanied by acute mental confusion or organic delirium.

• Abyssal / Profound — A quality belonging to the abyss or relating to the deepest zones of the oceans (usually below 2000-3000 meters), characterized by total darkness, immense pressure, and low temperatures. In psychology, the term qualifies the hidden elements of the human psyche, originating from the deepest layers of the unconscious.
• Abyssalness / Abyssal quality — The state, quality, or character of being abyssal. It denotes the property of having immense depth, either in a physical sense (specific to oceanic trenches) or in a figurative sense (referring to the unbridgeable profundity of thought, inner feelings, or layers of the unconscious).
• Abyssinia — The historical and traditional name under which the Ethiopian Empire and the Horn of Africa region were known in European cartographic, political, and diplomatic documents until the mid-20th century.
• Abyssinian — A person belonging to the native population of former Abyssinia (modern-day Ethiopia) or originating from there. As an adjective, it denotes anything pertaining to Abyssinia, its inhabitants, or the culture of this historical region in the Horn of Africa. In zoology, it qualifies a famous breed of domestic short-haired cats known for their elegant appearance, resembling the felines venerated in ancient Egypt.
• Abyssinian (feminine) — The feminine form of the term 'abisinian'. It denotes a woman who belonged to the native population of former Abyssinia or a feminine quality associated with this region. In a zoological context, it refers directly to a female cat of the Abyssinian breed.
• Abyssinicus — A specific epithet used in Latin binary nomenclature to designate species of plants, birds, or animals native to the historical region of Abyssinia (modern-day Ethiopia) or endemic to the Horn of Africa. The presence of this adjective in the scientific name indicates the native biogeographical area where the species was first identified, described, or classified.
• Deep — Extending far downward beneath a reference surface (of water, pits, valleys) or far inward from an edge or opening; located at a considerable distance from the surface. As a neuter noun, it designates a profound place, a chasm, the abyss, or the depth of a body of water. Figuratively, it describes an intense feeling, a penetrating mind, a detailed philosophical analysis, or a state of deep sleep.
• Deeply — As an adverb or adjective, it expresses being situated at a great depth, deeply immersed, sunken, or located far from the surface or edge; figuratively, it describes deep involvement in an activity, deep thoughts, or isolation in the thick of a forest. As a neuter noun, it denotes the bottom of a body of water, a chasm, an abyss, or the most secluded and untrodden part of a place.
• Anisophoria — A latent form of strabismus or heterophoria in which the angle of deviation of the visual axes varies depending on the direction of the gaze. This ocular neuromuscular anomaly manifests as asymmetrical positioning of the eyes when binocular fusion is interrupted, causing marked visual fatigue, headaches, or spatial orientation difficulties in patients looking toward the extremes.
• Aquanaut — A scholarly technical term or rare neologism used to denote a navigator, a deep-sea diver, or an operator of autonomous or remote-controlled underwater vehicles, specialized in exploring oceanic abysses or executing engineering works at great depths; a pioneer of deep submarine oceanography. In certain speculative registers, the term is built in analogy with 'astronaut', shifting the focus of exploration from cosmic space to the unknown aquatic depths.
• Arabis — A genus of herbaceous, annual or perennial plants within the family Brassicaceae (Cruciferae), commonly known as rockcress. Most species are native to temperate zones of the Northern Hemisphere and mountainous regions, characterized by often pubescent leaves and small, white, pink, or purple four-petaled flowers, valued in horticulture for rock gardens and ground cover.
• Arabis albida — A species of perennial herbaceous plant in the Brassicaceae family, taxonomically considered a synonym or variety of Arabis caucasica.

• Arabis blepharophylla — A rare species of perennial herbaceous plant, endemic to the California coast (United States), belonging to the Brassicaceae family. It is recognized in botany by its leaves with margins fringed with fine, stiff hairs (resembling eyelashes) and by its spectacular deep pink to purple flowers, highly valued in horticulture as an ornamental plant for rock gardens and containers due to its vibrant, compact growth.
• Arabis scopoliana — A species of perennial herbaceous plant in the Brassicaceae family, endemic to the mountainous regions of the southeastern Alps and northwestern Balkan Peninsula (Dinarides). It is an alpine-orophytic plant adapted to thriving on calcareous screes and rock crevices at high altitudes, characterized by compact rosettes of glabrous or slightly pubescent leaves and short stems bearing white flowers, holding high significance in regional phytogeographic studies.
• Arabism — A word, expression, or grammatical structure borrowed from an Arabic dialect into another language; a linguistic feature specific to the Arabic language.
