Here's how it works:
* Verb: "arrive"
* Adjective (using -al): "arrival"
To change a verb into a noun, you might use these suffixes:
* -er: "teach" becomes "teacher"
* -ing: "run" becomes "running"
* -ment: "govern" becomes "government"
* -tion: "create" becomes "creation"
* -ance: "perform" becomes "performance"
Remember, there are many ways to form nouns, and not every verb will have a noun form using a simple suffix. Sometimes you need to use a completely different word.
