The word 能够 is formed by combining two individual characters, each with its own core meaning, into a single conceptual unit. The first character, 能, originates from an ancient pictograph of a powerful animal (like a bear) and carries the fundamental idea of "ability" or "capability". The second character, 够, is itself a compound meaning "to reach" or "to be sufficient", composed of elements suggesting bending to attain an abundance. Therefore, 能够 is conceptually constructed by fusing the notion of inherent "capability" (能) with the idea of "reaching a point of sufficiency" (够), to jointly express the meaning of "to be able to" in the sense of having the capacity to adequately accomplish something.
