The word **篱笆** (líba, meaning "fence" or "hedge") is formed through a common Chinese morphological process called **synonym compounding**, where two characters with similar or identical meanings are combined to create a single, more concrete or nuanced term. Both **篱** and **笆** individually mean types of fences or enclosures, often made from bamboo or twigs, and both share the **竹 (bamboo)** radical, visually indicating their material. By pairing these two near-synonyms, the compound solidifies the specific concept of a woven or rustic barrier, making the meaning more explicit and stable than either character alone.
