The suffix "-tion" is commonly used in the English language to form nouns. It typically indicates the action or process of a verb, transforming it into a noun that describes the result or state of that action. For example, from the verb inform, we get the noun information, which refers to the knowledge or details provided. This suffix is derived from Latin, where it also served a similar purpose. Words like creation from create and celebration from celebrate illustrate how "-tion" helps convey the essence of an action in a noun form, making communication clearer and more precise.
