破裂 (pò liè) is a compound verb meaning 'to split apart' or 'to break down', often used metaphorically for relationships, agreements, or trust that suddenly fail or disintegrate. The character 破 means 'to break, to destroy', while 裂 means 'to split, to crack' — together they emphasize a complete, often irreversible separation. Unlike physical breaking (e.g., a cup shattering), 破裂 usually implies emotional or social rupture: friendships ending, diplomatic ties collapsing, or marriages dissolving.

This word carries a formal and slightly solemn tone, common in news reports, literature, and serious conversation. It’s rarely used for minor disagreements — instead, it signals a definitive, often painful, endpoint. While it can describe literal cracks in objects (e.g., a ruptured pipe), its dominant usage is abstract and interpersonal. Learners should avoid using it for everyday arguments; words like 闹矛盾 (nào máodùn) or 吵架 (chǎojià) are more appropriate for ordinary conflicts.
