Have you seen that new office building downtown?

Yeah, I noticed it looks really windowless from the outside.

I heard they designed it that way for better energy efficiency.

That makes sense, but it must feel so dark inside!

Synonyms & Antonyms

Root Explanation

Windowless → It is formed from "window" (from Old Norse *vindauga*, meaning wind eye) and "-less" (meaning without). The word "windowless" means without a window.

Memory Tip

Think of a place that is missing a 'window' — the '-less' indicates the absence of something, so 'windowless' means it has no windows.
