解决 (jiě jué) is a transitive verb meaning 'to solve' or 'to resolve'—typically referring to problems, difficulties, conflicts, or practical issues. The first character 解 (jiě) means 'to untie', 'to loosen', or 'to explain', suggesting the act of unbinding or clarifying something complex. The second character 决 (jué) means 'to decide' or 'to determine', implying finality and action. Together, they convey the idea of thoroughly dealing with an issue until it is settled and no longer problematic.

This word is commonly used in both spoken and written Chinese across formal and informal contexts—whether discussing technical challenges at work, personal disagreements, logistical hurdles, or everyday inconveniences. It often appears with objects like 问题 (wèntí, 'problem'), 困难 (kùnnan, 'difficulty'), or 矛盾 (máodùn, 'conflict'). While it carries a neutral-to-positive connotation, it implies effort and effectiveness—not just attempting, but succeeding in resolution.
