• Achromatization — The act of achromatizing and its result; a technical or experimental process through which the chromatic aberrations of an optical system consisting of lenses or prisms are corrected and eliminated. This structural phenomenon allows light beams of different wavelengths to reunite at a common focal point, ensuring highly clear images without artificial color fringes.
• Aethionema grandiflorum — Scientific name of the Persian stonecress, a perennial species from the Aethionema genus, native to the mountainous regions of the Caucasus, Iran, and Turkey, considered one of the most spectacular in the genus.

• Allium aflatunense — The scientific name of an ornamental onion species in the family Amaryllidaceae, native to the mountainous regions of Central Asia (Kyrgyzstan, Uzbekistan).

• Allochore — A term used to describe an organism, particularly a plant or vegetable species, dispersed into territories outside its native range through external, non-biological, or accidental dispersion means (such as human activity, wind, or water currents). In structural ecology, it defines allochthonous species introduced into a new habitat, where they may become naturalized or invasive.
• Allochory — A phenomenon or modality of seed, spore, or fruit dispersal through external factors or vectors that are independent of the plant's own biological mechanisms (such as wind, water, animals, or human activity). This structural mechanism ensures the colonization of new geographical habitats and prevents intraspecific competition near the parent plant.
• Anachromatic — Not chromatic; an optical system, lens, or transparent medium that does not produce chromatic aberrations or that has been partially or totally corrected against light dispersion. In a precise structural sense, it describes the property of a device to transmit light beams without separating the component colors of the visible spectrum, guaranteeing a faithful and clear rendering of the edges of projected images.
• Anahita — An ancient Persian divinity of cosmic waters, fertility, healing, and wisdom, structurally venerated in Zoroastrianism and throughout the Achaemenid Empire.
