Definition

A line along the shore where the water meets the land, often marked by debris or seaweed left by the tide.

Conversation

Did you notice the tideline when we were at the beach yesterday?

Yeah, it was really interesting to see all the seaweed and debris there.

I wonder what causes the tideline to form like that.

It’s probably due to the different currents meeting at that spot.

Root Explanation

Tideline → It is formed from "tide" (from Old English *tīd*, meaning time or season) and "line" (from Old English *līn*, meaning a cord or string). The word "tideline" refers to the line or mark left by the tide on the shore.

Memory Tip

Think of the 'time' ('tide') when the water reaches the shore, and the 'line' that it leaves behind — that's what a tideline is.
