Conversation

Did you notice the backwash from the waves at the beach yesterday?

Yeah, it was pretty strong and pulled me back a little.

I thought it was interesting how the backwash affects the sand too.

Definitely! It keeps changing the shape of the shore.

Root Explanation

Backwash is formed from "back" (from Old English "bæc", meaning the rear or reverse side) and "wash" (from Old English "wæscan", meaning to cleanse with water). The term describes the water that flows back after being disturbed, particularly in a body of water.

Memory Tip

Think of water flowing 'back' ('back') after being 'washed' ('wash') — that's what backwash refers to.
