The suffix -tion is used to form?

The suffix "-tion" is used to form nouns. It typically indicates an action, process, or state.

Here are some examples:

* Action: "creation" (the act of creating)

* Process: "education" (the process of learning)

* State: "inflation" (the state of prices rising)

The "-tion" suffix is often added to verbs to create nouns that represent the action of the verb. For example:

* Verb: "act" --> Noun: "action"

* Verb: "create" --> Noun: "creation"

* Verb: "translate" --> Noun: "translation"
