What does siffix -tion do to a word?

The suffix "-tion" typically transforms a verb into a noun. It often indicates the action, state, or process described by the verb.

Here are some examples:

* Act (verb) -> Action (noun) - the process of acting

* Create (verb) -> Creation (noun) - the act of creating something

* Inspire (verb) -> Inspiration (noun) - the act or power of inspiring

Sometimes, "-tion" can also be added to adjectives, forming nouns that represent the state or quality described by the adjective.

However, "-tion" is not always used in the same way. There are some words that don't follow the general rule and have different meanings.

Ultimately, it's best to check the dictionary for the specific meaning of a word ending in "-tion" to ensure you understand its correct usage.
