#compound

• Shell game — An illegal and fraudulent game of chance, usually practiced in crowded public places (fairs, markets, stations), consisting of spectators guessing the hidden object (a ball, a coin) under one of three cups, thimbles, or playing cards manipulated quickly and with manual skill by a swindler. In a figurative sense, the term describes an action based on deception, manipulation, hidden tricks, or a duplicitous strategy by which the truth is concealed.
• Azure-blue — Being of a blue color with light and luminous shades, similar to that of a clear summer sky or tropical marine waters; intense azure. The term is frequently used in descriptions of natural landscapes, in visual arts, or in the textile industry to evoke an atmosphere of serenity, clarity, and structural purity.
• Light-blue — Having a blue color of low intensity, with a pronounced white tint; light blue or attenuated azure. The term is used in everyday, technical, or industrial language to differentiate pastel and bright shades from dark or saturated ones within the structural color spectrum.
• Carpenter bee — A popular name attributed to the bumblebee or carpenter bees of the genus Xylocopa, characterized by a massive, robust body of a shiny-black or dark-violet color, with opaque wings and a deep buzz, which build their nests by burrowing tunnels into the dry wood of rural structures.
• Bumblebee — A popular name given to the bumblebee or to certain species of large flies, horseflies, or solitary ground wasps, characterized by a darker, blackish or coppery coloration and a loud buzzing sound, which vaguely resemble bees but do not produce honey.
• Albon compound — A commercial or technical name attributed to a chemical compound of the sulfonamide class, used historically in veterinary medicine for its antibacterial properties; a light-colored, whitish or greyish mineral, reported in certain limestone geological structures.
• Albuminate — A chemical compound, salt, or molecular combination resulting from the reaction of an albumin-class protein with a base, an oxide, or a heavy metal; a complex organic substance used historically in pharmacology or dyeing due to its structural binding properties.
• 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.
• Alkaloid — A nitrogenous organic substance, typically possessing a basic (alkaline) character and a complex heterocyclic structure, primarily biosynthesized by plants, but also by certain fungi or animals. Alkaloids exhibit intense pharmacodynamic action on the central nervous system and the human body, functioning, depending on the dosage, as essential medicines, stimulants, or highly violent poisons (for example: morphine, caffeine, nicotine, atropine, quinine).
• Alcohol — An organic compound containing one or more hydroxyl (-OH) functional groups bound to a saturated carbon atom. In common parlance, the term refers to ethanol or ethyl alcohol, a volatile, flammable liquid obtained through the fermentation of sugars or chemical synthesis, acting as the active ingredient in intoxicating beverages and an essential solvent in industry and pharmacy.
• Alcohol — The standard and widely adapted Romanian spelling for alcohol. An organic compound characterized by the presence of one or more hydroxyl groups attached to a saturated alkyl radical. It represents the structural baseline of ethanol used as an antiseptic, general industrial solvent, or as the major psychoactive ingredient in a wide range of fermented or distilled beverages.
• Alcoholate — In chemistry, an organic compound obtained by replacing the hydrogen atom in the hydroxyl group of an alcohol with a metal atom (alkoxide). In pharmacy, the term designates a medicinal liquid preparation obtained by distilling alcohol over aromatic plant substances, used as an antiseptic or flavoring remedy.
• Alcoholizable — Capable of being alcoholized; a substance, organic compound, or liquid mixture that has the structural property to receive alcohol into its composition or to chemically react with ethanol. In biology, it describes a tissue or organic sample capable of being stably impregnated with alcohol for cellular fixation or preservation.
• Aldehyde — An organic compound containing a carbonyl functional group bonded to a hydrogen atom (the formyl group, -CHO), necessarily located at the end of a carbon chain. Aldehydes are obtained industrially or in the laboratory through the dehydrogenation or controlled oxidation of primary alcohols and are widely used in chemical synthesis, the perfume industry, and disinfectant production.
• Aldeide — An old or regional orthographic variant for the term 'aldehyde'; an organic compound characterized by the presence of the carbonyl functional group (-CHO) bonded to a hydrocarbon radical or a hydrogen atom. Although current standards of the Romanian Academy mandate the spelling with 'h', this form is still found in early technical textbooks or vintage translations.
• Aldimines — A class of nitrogenous organic compounds formally derived from an aldehyde, by replacing the carbonyl oxygen atom with an imino group (=N-R or =N-H). These represent secondary imines or Schiff bases with the general structure R-CH=N-R', serving as highly valuable intermediates in fine organic synthesis, drug manufacturing, and enzymatic biochemistry.
• Aldol — A bifunctional organic compound containing both an aldehyde group (-CHO) and a hydroxyl group (-OH) attached to a carbon atom in the beta position (b-hydroxyaldehyde). The term specifically designates 3-hydroxybutanal, obtained via the aldol condensation of two acetaldehyde molecules, serving as a critical intermediate in the industrial synthesis of butadiene and other macromorphological compounds.
• Aldoxime — A nitrogenous organic compound belonging to the oxime class, formally or practically obtained through the condensation reaction of an aldehyde with hydroxylamine (NH2OH), having the general structure R-CH=N-OH. This type of oxime is characterized by the presence of a hydrogen atom bonded to the azomethine carbon, unlike ketoximes, serving as a valuable intermediate in nitrile and amide synthesis.
• Aldrofan — A historical or regional commercial name for a pharmaceutical compound utilized in treating acute respiratory disorders or as an adjuvant agent in dermatological therapy; in a generic sense, it represents a specific chemical formulation stored as tablets or stabilized solution according to industrial pharmacological standards.
• Creeping pathweed — A regional popular name assigned to a species of creeping herbaceous plant with long, flexible stems that often grows along roads, paths, or ditch edges. Structurally, the name suggests the plant's ability to rapidly expand across the soil, forming dense vegetation networks that seem to 'run' parallel to access pathways.
