• Abyssalness / Abyssal quality — The state, quality, or character of being abyssal. It denotes the property of having immense depth, either in a physical sense (specific to oceanic trenches) or in a figurative sense (referring to the unbridgeable profundity of thought, inner feelings, or layers of the unconscious).
• Aquatint — An artistic printmaking process on metal plates (copper or zinc) related to etching, used to achieve wash effects, granulated textures, and velvety modulated tones of gray or color; also, it designates the print impressed via this technique. This structural style relies on dusting a fine resin powder (rosin) onto the matrix, which, after heating and controlled acid corrosion, creates nuanced areas.
• Deep — Extending far downward beneath a reference surface (of water, pits, valleys) or far inward from an edge or opening; located at a considerable distance from the surface. As a neuter noun, it designates a profound place, a chasm, the abyss, or the depth of a body of water. Figuratively, it describes an intense feeling, a penetrating mind, a detailed philosophical analysis, or a state of deep sleep.
• Depth — The dimension of an object, cavity, or space measured vertically from top to bottom, from a reference surface to the floor or base; a considerable distance from the outer edge toward the interior of a medium. Figuratively, the term defines the intensity, depth, or thoroughness of a feeling, philosophical thought, or scientific analysis.
• Deepen — The act of making deeper, increasing the depth of a cavity, a trench, or a body of water; (figuratively) an intellectual or analytical process through which a problem, an idea, or a study is thoroughly investigated, moving beyond superficial aspects to understand its essence. In traditional spelling, it represents the infinitive or present indicative form of extending vertical or conceptual dimension.
• Deeply — As an adverb or adjective, it expresses being situated at a great depth, deeply immersed, sunken, or located far from the surface or edge; figuratively, it describes deep involvement in an activity, deep thoughts, or isolation in the thick of a forest.
