Canal synonyms like waterway, channel, and conduit describe a man-made or natural passage for water, transport, or irrigation. For example, “The canal carried boats through the city,” or “Farmers rely on irrigation channels for crops.”
If you’re writing or speaking about waterways, engineering, or geography, each word highlights a slightly different meaning—from natural streams to engineered passages for water transport.
In this guide, you’ll learn the meaning and example sentences for each canal synonym so you can express waterways, channels, and passages with precision and clarity.
What Does “Canal” Mean?
The word “canal” refers to a man-made or artificial waterway constructed for navigation, irrigation, or drainage. It can also refer to a natural channel shaped for a specific function.
Examples:
- “The Panama Canal is one of the most important waterways in the world.”
- “The canal behind the village is used for irrigation.”
“Canal” emphasizes controlled water flow, transport, or human-engineered paths. Its tone is neutral, often used in geography, engineering, or environmental contexts.
