Frequently Asked Questions
No. A waterfall is a vertical drop of water from a height (like Niagara). An overfall is typically a horizontal but turbulent and breaking flow of water in the sea or a river, often over a hidden obstacle.
It would be very unusual unless you are specifically discussing nautical navigation, hydrology, or describing a known local hazard on the water. Most native speakers would not know this word.
It can be used as a verb (meaning to overflow or fall over), but this usage is considered archaic. The modern term is overwhelmingly a noun.
It can create violent, unpredictable waves and currents that can swamp or capsize a vessel, especially a small one.
