Synonyms & Antonyms

Root Explanation

Insubstantial → It is formed from "in-" (meaning not) and "substantialis" (from Latin "substantia", meaning substance or essence). The word describes something that does not have substance or is not solid or real.

Memory Tip

Think of 'not' ('in-') having 'substance' ('substantia') — that's why insubstantial means lacking real substance.
