The word 懂得 is formed through the combination of the character 懂, which means "to understand" or "to comprehend", and the character 得, which here functions as a complement indicating attainment, possibility, or the achieved state of an action. By joining them, the meaning evolves from the basic act of "understanding" to convey a sense of "to have come to understand", "to have grasped", or "to know how to", emphasizing a successful or complete acquisition of knowledge or skill from the process. It is a conceptual fusion where the second character deepens and completes the action expressed by the first.
