Ungrounded → It is formed from "un-" (meaning not) and "grounded" (from the root "ground" which comes from Old English "grund", meaning the bottom or foundation). The word "ungrounded" means not having a solid foundation or basis.
Think of 'not' ('un-') having a 'foundation' ('ground') — that's why ungrounded means lacking a solid base.
