击却 (jī què) is a classical Chinese verb meaning 'to repel', 'to drive back', or 'to defeat'—especially in contexts of military resistance, overcoming obstacles, or thwarting attacks. The character 击 (jī) means 'to strike' or 'to attack', while 却 (què) carries the sense of 'to retreat', 'to withdraw', or 'to reject'. Together, they form a compound implying forceful reversal: striking so as to cause the opponent or threat to fall back or be defeated. This term appears primarily in historical texts, literary prose, formal speeches, and idiomatic expressions—not in everyday spoken Mandarin.

It conveys a decisive, often heroic or strategic, victory rather than mere winning; emphasis lies on pushing back an active threat. You’ll encounter it in descriptions of ancient battles, moral resistance ('repelling corruption'), or metaphorical struggles ('defeating temptation'). Because of its literary register, modern speakers typically use more common alternatives like 击败 (jībài) or 打退 (dǎtuì) in daily speech.
