击溃 is a compound verb meaning 'to crush' or 'to rout', especially in military or competitive contexts. It combines 击 (jī), meaning 'to strike' or 'to attack', and 溃 (kuì), meaning 'to collapse' or 'to disintegrate'. Together, they convey the idea of delivering a decisive blow that causes the opponent’s forces—or morale—to break apart completely. The word emphasizes total, overwhelming defeat rather than mere loss.

This term is commonly used in historical narratives, news reports about conflicts, sports commentary, and strategic discussions. While it originated in warfare, it's now extended metaphorically—for example, to describe crushing an opposing argument, dismantling a corrupt system, or overwhelming a rival team. It carries a formal, often dramatic tone and rarely appears in casual daily speech. Note that 击溃 is transitive and always requires a direct object—such as an army, enemy, plan, or resistance.
