1. To carve or scoop out: This is the most literal meaning. You might "gouge" a hole in a piece of wood with a chisel, or "gouge" out a piece of pumpkin for carving.
2. To cheat or overcharge: This is a more figurative meaning. If someone "gouges" you, they are charging you an unfairly high price for something. For example, "The hotel tried to gouge us on the price of the room."
3. To injure by digging or tearing: This meaning usually refers to a physical injury. For example, "The accident gouged a deep hole in the car's bumper."
4. To press or force something into something else: This meaning is less common, but it can be used in contexts like, "The artist gouged the paint into the canvas."
The specific meaning of "gouge" will depend on the context in which it is used.
