invisible (adjective)

Something that is invisible cannot be seen by the eye, often because it is transparent or hidden. It is frequently used to describe physical objects that are impossible to detect or abstract concepts that go unnoticed.

💡 Memory Tip

Think of 'IN' (not) + 'VISIBLE' (able to be seen). If it's IN-visible, it's NOT-visible.
