Here are some examples:
* Purity (condition of being pure)
* Clarity (condition of being clear)
* Security (condition of being secure)
* Prosperity (condition of being prosperous)
* Stability (condition of being stable)
However, it's important to note that not all words describing a condition use the "-ity" suffix. Some words might use other suffixes like "-ness" (e.g., happiness, sadness) or "-hood" (e.g., childhood, womanhood).
Additionally, some words related to a condition might not use any suffix at all (e.g., health, wealth).
