Did you see that old building near the river?

Yeah, I think it used to be a factory or something.

I heard they’re planning to clean up the outfall there.

That would be great! It could really improve the area.

Root Explanation

Outfall → It is formed from "out-" (meaning outside or outward) and "fall" (from Old English "feallan", meaning to fall). The word "outfall" refers to the place where something, such as water, flows out or falls out into another body, typically a river or sea.

Memory Tip

Think of something flowing 'out' ('out-') and 'falling' ('feallan') into another area — that's why outfall means the place where water flows out.
