The Chinese word **扩展 (kuòzhǎn)** is a compound formed by combining two characters with related meanings: **扩 (kuò)**, which means "to enlarge" or "to expand," and **展 (zhǎn)**, which means "to unfold," "to spread out," or "to exhibit." Together, they create a coordinated or complementary compound where both elements contribute to an overarching concept of expansion. The first character, **扩**, provides the core action of making something larger in scope or scale, while the second, **展**, adds the nuance of stretching that scope outward, unfolding it into a broader area or application. Thus, the compound **扩展** semantically means "to expand and extend," effectively conveying the idea of growth in breadth, range, or capacity.
