#orbit

• Alloglottic — Relating to persons, communities, or population groups: speaking a language other than the official or majority language of the state or region in which they reside; a foreign-speaking person integrated into a linguistic environment different from their native one. In demographic studies, the term describes linguistic minorities that preserve their mother tongue alongside the use of the dominant administrative language.
• Not now — A contracted, popular, or regional phonetic form resulting from the rapid blending of the temporal adverb 'acum' (in regional variants 'amu' or 'amuș') with the negation 'nu'. It is used in current informal speech to express an immediate contextual negation, hesitation, or a spontaneous reaction of rejection regarding a present action.
• Analemma — The elongated figure-eight curve (or asymmetric infinity symbol) plotted on a diagram or terrestrial globe, obtained by photographing the Sun successively throughout a calendar year at the exact same hour and from the same fixed physical location. This structural visual phenomenon is the direct result of the axial tilt of the Earth combined with the eccentricity of its elliptical orbit around the Sun, historically used in gnomonics for calibrating sundials and calculating the equation of time.
• Anophthalmia — A severe and rare congenital anomaly characterized by the complete absence of one or both eyeballs, caused by the developmental arrest of the optic vesicles during the first weeks of intrauterine life. This structural lack of the eye results in reduced orbital and eyelid volume, frequently associated with genetic mutations or complex malformative syndromes.
• Season — Each of the four main divisions of the year (spring, summer, autumn, and winter), structurally determined by the Earth's position on its orbit around the Sun and the tilt of the terrestrial axis. This cyclical phenomenon generates regular climatic variations, systematic changes in the length of day and night, as well as profound transformations in the biological rhythm of global flora and fauna.
• Previous female speaker — A female person who has spoken before others in a meeting, conference, or public debate. In discourse analysis, the term designates the speaker whose arguments, ideas, or conclusions serve as a point of reference or basis of rebuttal for subsequent participants.
• Antilunar point — A hypothetical or real point on the celestial sphere or Earth's surface located in direct opposition (180 geometric degrees away) to the Moon (Selene). In a structural sense, it defines the axis diametrically opposite to the lunar vector, utilized in celestial mechanics calculations to determine antipodal gravitational resonance points or in astronomical meteorology to locate rare optical phenomena reflected symmetrically to the natural satellite's position.
• Apocenter — The point in the elliptical orbit of a celestial body or an artificial satellite that is farthest from the center of attraction; the extremity of the orbit's major axis opposite to the pericenter. Depending on the central body around which the orbital motion takes place, the term takes specific names, such as apogee for Earth or aphelion for the Sun.
• Apogalacticon — The point in the elliptical orbit of a star, a stellar cluster, or a celestial body orbiting a galaxy's nucleus that is farthest from the galactic center; galactic apoapsis. In stellar dynamics, this point represents the moment when the body's orbital velocity reaches its minimum value due to the maximum distance from the central mass.
• Apogee — The point in the elliptical orbit of the Moon or an artificial satellite that is farthest from the Earth; terrestrial apoapsis. Figuratively, the term denotes the highest point, climax, or maximum level of development, glory, power, or brilliance that a person, a civilization, a science, or a work of art can reach.
• Apse — A monumental semicircular, polygonal, or rectangular recess, vaulted in the shape of a semi-dome, located behind the nave of a Christian church or at the back of an ancient Roman basilica, housing the imperial throne or the liturgical altar. In astronomy, it designates either of the two extreme points (closest or farthest) of the elliptical orbit traveled by a celestial body.
• Apsidal — Pertaining to an apse, relating to an apse, or having the shape of an apsidal structure; a vaulted or semicircular architectural element specific to the altar of Christian churches. In structurally applied astronomy, the term describes the imaginary line connecting the farthest or closest points to the center of attraction in the elliptical trajectory of a celestial body.
• Arabophone — Arabic-speaking; a person who uses the Arabic language as a mother tongue or as their primary medium of daily communication. In an extended sense, the term describes communities, geographic regions, media outlets, or literary publications worldwide that conduct their activities, transmit messages, or draft official documents in this Semitic language.
• Arabophone — A woman who speaks the Arabic language as a mother tongue or primary means of communication; the feminine form of the term arabofon. As an adjective, it describes feminine entities, such as a community, population, radio broadcast, or administrative region, within which the Arabic language is currently and widely utilized.
• Argotist — A person who frequently, consciously, or predominantly uses an argotic language in everyday communication; a member of a codified social group who masters the secret rules of a specific community. As an adjective, it describes a verbal behavior centered around cryptic, nonconformist structures.
• Female argotist — A woman who frequently, consciously, or predominantly uses an argotic language in everyday communication; a female member of a codified social, professional, or subcultural group who masters its secret linguistic norms. As an adjective, it describes a female person or verbal style focused on nonconformist, cryptic street expressions.
• Assimilated — Having been absorbed, integrated, transformed, or structurally incorporated into a pre-existing system, becoming a homogenous part of it. In biology, it describes nutrients converted into living matter; in psychology, knowledge organically internalized into the cognitive structure; in linguistics, a sound phonetically modified under the influence of a neighboring one.
• Aspirated consonant — A consonant whose pronunciation involves an additional and audible emission of breath, specific to many Germanic or Oriental languages; as an adjective, it describes a feminine entity, a surface (such as a carpet), or a liquid or gaseous substance that has undergone pneumatic absorption.
• Asteroid — A rocky or metallic celestial body, much smaller than a planet, orbiting the Sun, with most clustered in the main belt between Mars and Jupiter; as an adjective, it describes an object, organism, or structure exhibiting a stellar shape or star-like radial symmetry.
• Astronaut — A person specifically trained and qualified to navigate in outer space or to serve as a crew member on a spacecraft, orbital station, or interplanetary vehicle. Their activity involves piloting spacecraft, conducting scientific experiments in microgravity, and performing extravehicular activities (EVA), being the standard term traditionally used by the American (NASA) and Western European aerospace programs.
