Root Explanation

**Unseriousness** → It is formed from "un-" (meaning not) and "serious" (from Latin *serius*, meaning grave or important) and "-ness" (meaning the state of being). The word "unseriousness" refers to the state of not being serious or lacking seriousness.

Memory Tip

Think of 'not' ('un-') being combined with 'grave' or 'important' ('serius') to remember that 'unseriousness' means lacking seriousness.
