• Abasic — A medical term describing a person affected by abasia, characterized by the partial or total inability to walk or maintain an erect posture, despite muscular strength, sensation, and coordination of the limbs being completely preserved in the recumbent position. It is encountered in organic neurological conditions (frontal or cerebellar lesions, extrapyramidal syndromes) or in psychogenic conversion disorders (classical hysteria, presenting as astasia-abasia syndrome).
• White — Having the color of snow or milk, resulting from the total and simultaneous reflection of all rays within the solar spectrum; devoid of coloring, pale, or immaculate. As a neuter noun, it denotes the color itself, a blank space or, figuratively, a state of purity, innocence, transparency, or legality of an action or structural system.
• Bluish — Tending toward blue, having a faint, secondary, or faded shade of blue; of an attenuated or pastel azure. The term is used in everyday, scientific, or industrial language to describe the discrete coloration of certain minerals, anatomical textures, meteorological phenomena, or pigment mixtures.
• Alkalescent — Becoming alkaline; showing a tendency to acquire basic (alkaline) properties, or having weakly expressed or developing alkaline characteristics. In biology, the term often describes substances or organic media undergoing a phase of slight alkalinization as a result of specific chemical reactions.
• Alkalescence — The property of being alkalescent; the state of a substance, solution, or organic medium showing a weak, incipient, or developing alkalinity. It represents the transitional phase or moderate chemical character where the pH evolves from neutral toward basic levels without reaching a highly corrosive value.
• Alkalic — Containing alkali; having basic or alkaline properties; alkaline. In geology and petrography, the term describes igneous rocks or minerals rich in alkali metals (such as sodium and potassium), characterized by a specific chemical composition that influences the structure and evolution of crustal melts.
• Alkaline — Pertaining to or characteristic of bases (alkali); having basic properties, characterized by a pH value greater than 7. In chemistry, the term describes solutions that neutralize acids or elements from the first group of the periodic table (alkali metals); in geology, it defines rocks or minerals rich in sodium and potassium oxides.
• Alkalinity — The property of being alkaline; the total concentration of basic substances in a solution capable of neutralizing hydrogen ions. In hydrology and ecology, it represents the buffering capacity of water against acidification, primarily determined by the presence of carbonate, bicarbonate, and hydroxide ions.
• Alkali — An archaic form or less frequent spelling variant for the noun 'alkali'; a generic name given to the soluble hydroxides of alkali metals. In old scientific literature, the term defined any compound capable of neutralizing acids and altering the coloration of plant-based chemical indicators.
• Literacy teacher — A person engaged in teaching literacy to a group of people, instructing illiterate individuals to read and write; an instructor or educator involved in social campaigns to eradicate illiteracy. As an adjective, it describes a factor, a teaching program, or a pedagogical tool designed to trigger and support the learning of the basic notions of the alphabet.
• Anorthite — A mineral belonging to the silicate class, representing the pure calcium endmember of the plagioclase feldspar isomorphic series (calcium aluminum silicate). It crystallizes in the triclinic system, features a white, grayish, or reddish color, and is a common structural constituent in basic and ultrabasic igneous rocks (such as gabbros and basalts), as well as in some metamorphic rocks or meteoritic materials.
• Arithmetic — The oldest and most elementary branch of mathematics, dealing with the study of numbers, their properties, and fundamental operations such as addition, subtraction, multiplication, and division. In an educational sense, it represents the core school subject introducing primary numerical calculus, forming the foundation for advanced algebraic structures and number theory.
• Augitite — An effusive, ultrabasic, and melanocratic igneous rock, completely lacking feldspars, composed primarily of large augite and magnetite crystals embedded in a glassy or microcrystalline basaltic groundmass. In structural geology, it represents a rare variety of volcanic pyroxenite.
