The Chinese word **溶解** (róngjiě), meaning "to dissolve," is a compound formed by combining two characters, each contributing semantically to the concept: **溶** (róng) specifically carries the meaning of "to dissolve" or "melt," often implying a solid dispersing into a liquid, while **解** (jiě) means "to separate," "untie," or "break apart." Together, they create a precise term that vividly describes the physical process where a substance (the solute) is broken apart and dispersed uniformly within a solvent, resulting in a solution. This formation follows the common Chinese lexical pattern of combining related-meaning characters (并列结构) to produce a nuanced and technically accurate word.
