I heard some rumors about you that seem groundlessly mean.

Synonyms & Antonyms

Root Explanation

Groundlessly → It is formed from "ground" (from Old English "grund", meaning the solid surface of the earth) and "-less" (meaning without). The word "groundlessly" means without a basis in fact or reason, as if lacking a solid foundation.

Memory Tip

Think of something that has no solid foundation ('ground') and is 'without' ('-less') support — that's why groundlessly means without basis.
