Here are some examples:
* Act + ion = Action (the process of acting)
* Communicate + ion = Communication (the process of communicating)
* Educate + ion = Education (the process of educating)
* Construct + ion = Construction (the process of constructing)
* Operate + ion = Operation (the process of operating)
However, the meaning of "tion" can vary slightly depending on the specific verb it is attached to. Sometimes it can also denote a result or product of an action.
For example:
* Production (the result of producing)
* Motivation (the state of being motivated)
It's important to note that "tion" is not always the only suffix used to form nouns from verbs. Other suffixes, like "-ment," "-ance," and "-ence," can also be used.
