Synonyms & Antonyms

Root Explanation

Groundless → It is formed from "ground" (from Old English "grund", meaning the bottom or foundation) and "-less" (meaning without). The word "groundless" means without a foundation or basis, often referring to claims or beliefs that lack support.

Memory Tip

Think of something that has no 'foundation' ('ground') — that's why 'groundless' means lacking a basis.
