拼 means 'to strive, to exert oneself' and 命 means 'life' or 'one's life'. Together, 拼命 literally means 'to risk one’s life' — conveying extreme effort, urgency, or intensity. It functions almost exclusively as an adverb modifying verbs, describing how an action is performed: with frantic energy, desperate determination, or reckless abandon. It often implies physical or emotional exhaustion, urgency, or high stakes — like running to catch a train, studying for exams, or fighting off illness.

This word carries a slightly dramatic or colloquial tone and appears frequently in spoken Mandarin and informal writing. While not inherently negative, it suggests unsustainable effort — the speaker may be warning against overexertion or highlighting sheer willpower in adversity. It rarely appears in formal reports or academic texts, but is common in conversations, novels, and media depicting struggle or urgency.
