The Chinese word **呐喊** is a compound term formed by combining two characters with similar meanings: **呐** (nà), which means to shout or cry out, often with a sense of declamation or proclamation, and **喊** (hǎn), which means to yell, shout, or call out loudly. This combination creates a **reduplicative or synonymous compound**, where both components reinforce and intensify the core concept of a loud, forceful vocal outcry. The term conveys not just a simple shout, but often implies a cry of protest, a rallying call, or an expressive roar, famously used as the title of Lu Xun's short story collection *"A Call to Arms" (Nàhǎn)*, where it embodies the idea of crying out to awaken society.
