The word **决战** (juézhàn) is a compound word formed through the morphological process of **combination**, where two independent morphemes, each with its own meaning, are joined to create a new semantic unit. The first character, **决** (jué), carries the core meaning of "to decide" or "to determine," while the second character, **战** (zhàn), means "battle" or "war." When combined, they form a verb-noun structure where **决** modifies **战**, literally meaning a "deciding battle." This results in the comprehensive meaning of a "decisive battle" or "final showdown," a clash intended to settle the ultimate outcome of a conflict. The formation exemplifies how Chinese creates precise terminology by logically compounding conceptual components.
