"Concealable" Natural Recordings by Native Speakers
Concealable refers to something that can be concealed or hidden, often implying that it is secret or confidential.
The word "concave" refers to a shape that is curved inward or hollowed out. In other words, a concave surface is one that is deeper in the middle than at the edges. This concept is often used in mathematics, architecture, and engineering. For example, a concave mirror is one that is thicker in the middle than at the edges, whereas a convex mirror is one that is thicker at the edges than in the middle.
Concavities refer to hollow or curved inward parts or spaces. It can also describe a surface that is curved inward, such as the concavity of a mirror or the concavities of the human skull. In a broader sense, concavities can also refer to any inwardly curved or hollow feature, such as a valley or a depression in the earth's surface.
Concavity refers to a curved or bent shape that is inward, opposite of convexity. It is a property of a shape or a surface where it curves or bends inward, often forming a depression or a hollow. This term is commonly used in mathematics, physics, and engineering to describe the shape of a curve or a surface. For example, a sphere has a concave curvature when viewed from the outside, while a saddle-shaped surface has a concave curvature in two directions.
Hidden, secretive, or unobtrusive; kept from sight or knowledge; not openly shown or expressed.
