Conversation

I went swimming yesterday, and the water felt so depthless at the lake.

Really? That sounds a bit scary, to be honest.

It was! I couldn't see the bottom, which made it feel even more depthless.

I guess that adds to the thrill, but I'd be nervous too!

Synonyms & Antonyms

Root Explanation

Depthless → It is formed from "depth" (from Old English *deop*, meaning deep) and "-less" (meaning without). The word "depthless" means without depth or lacking depth.

Memory Tip

Think of something that is 'without' ('-less') 'depth' — that's why depthless means lacking depth.
