• To flatten — A rare regional or archaic verbal form meaning to flatten, smooth out, ram, or level a surface (especially the soil or soft clay), being partially a shortened phonetic variant or related to the action of flattening.
• Flattened — Having been made flat, smoothed, or leveled through pressing or mechanical finishing; figuratively, it describes a conflict, misunderstanding, or crisis that has been extinguished, calmed, or peacefully resolved. In biology or anatomy, it refers to an organ or anatomical structure naturally flattened or compressed along a specific axial direction.
• Flatten — To make flat, flatten, squeeze, or level a three-dimensional structure through external force or mechanical processing; as a reflexive verb, it represents the action of losing its natural relief, roundness, or curvature, becoming perfectly plane. In digital design and software, it refers to the process of merging multiple independent compositional layers into a single final two-dimensional image.
• Flattening — The act of flattening and its direct result; the geometric or mechanical transformation of a three-dimensional body through which it becomes flat, plane, or squashed under the influence of pressure, rolling, or percussion forces. In the field of digital graphics, it represents the irreversible process of merging superimposed transparent layers into a single unified two-dimensional matrix.
• Flattened — Having been brought into a flat, plane, or uniform shape through mechanical pressure, deformation, or industrial finishing; in a digital context, it represents a graphic document or image whose initial components and layers have been completely merged. In anatomy and biology, it describes an organ or structure that exhibits a naturally flattened or compressed shape.
• Applanata — A specific epithet used in Latin binary nomenclature to describe a species of plant, fungus, or fossil organism that exhibits a flattened, depressed, smooth, or horizontal structure. It is most frequently encountered in mycology, defining species such as Ganoderma applanatum, a parasitic bracket fungus growing on tree trunks in flat, rigid shelves.
• Applanatum — The neuter singular form of the scientific Latin specific epithet 'applanatus', used in binary nomenclature to denote species of fungi or plants that feature a visibly flattened, horizontal, and smooth body, cap, or anatomical structure. The most well-known example is Ganoderma applanatum, a perennial wood-decay fungus commonly called the artist's bracket, which grows on deciduous tree trunks in flat shelves.
