What is the differency between "difference" and "differency? Nobody uses "differency" And what is the difference between "preciseness" and "precision"? There isn't much of a difference. Precision is more commonly used. -ness words describe a state or quality and -ion should describe a process or action. And what is the difference between "safety" and "safeness"? When do you use which one?? Same thing, but safety is more commonly used. Not many people say "safeness"

"Differency", "Preciseness", and "Safeness" aren't words I've ever heard or seen; I'm fairly sure they aren't actually real words.

thank you two a lot...
