航道

航道 refers to a designated waterway for ships and boats, typically marked or regulated for safe navigation. It is commonly used in maritime contexts, such as in ports or along rivers and seas.

The character 航 (háng) means 'to sail' or 'navigation,' while 道 (dào) means 'road' or 'path.' Together, they literally translate to 'navigation path,' emphasizing the structured route for vessels.

航 is often associated with transportation by sea or air, and 道 can refer to any kind of path or route. In practical use, 航道 is essential for maritime safety, traffic control, and logistics planning, especially in busy waterways like the Yangtze River or the South China Sea.
