侥幸 (jiǎo xìng) literally combines 侥 (jiǎo), meaning 'to seek advantage by underhanded means' or 'unjustified hope', and 幸 (xìng), meaning 'luck' or 'fortune'. Together, they express an outcome achieved not through merit, preparation, or fairness—but purely by sheer, often undeserved, luck. It carries a subtle nuance of guilt, unease, or moral ambiguity: the speaker usually acknowledges that the favorable result was unwarranted or even inappropriate.

This word is commonly used to describe narrowly avoiding negative consequences (e.g., escaping punishment), succeeding despite negligence, or benefiting from an improbable coincidence—often with self-awareness or criticism. It frequently appears in contexts involving risk, rules, ethics, or consequences, and is rarely used in positive, celebratory ways. In speech and writing, it often co-occurs with verbs like 'think', 'hope', 'escape', 'avoid', or 'succeed', and may be modified by adverbs like 'merely' or 'barely'.
