The Chinese word **阻拦** (zǔlán) is a **verb** meaning "to block" or "to obstruct," and it is a typical example of a **synonymous compound** formed through the combination of two characters with closely related meanings. The first character, **阻** (zǔ), primarily conveys the sense of "to hinder" or "to impede," often implying a barrier or obstacle. The second character, **拦** (lán), means "to block" or "to bar," usually with a more direct, physical connotation of interception. By pairing these two semantically similar morphemes, the compound word **阻拦** is created, reinforcing and intensifying the core concept of actively preventing or stopping an action or progress, resulting in a term stronger and more nuanced than either character alone.
