The state of being whole or undamaged, without any parts missing or broken.
The ancient artifact was preserved in perfect intactness after centuries.
Intactness is formed from "intact" (from Latin "intactus", meaning untouched) and the suffix "-ness" (meaning the state or quality of). The word "intactness" refers to the state of being untouched or unbroken.
Think of something that is 'untouched' ('intact') and the '-ness' indicating a state. This helps you remember that 'intactness' means the quality of being untouched.
