Step 3: Categorize Words by Suffix

#### -ation

#### -er
- Monarch → Monarcher (Note: This is not a standard English word, but it fits the pattern)
- Bright → Brightener
- Found → Founder
- Improve → Improver
- Treat → Treater
- Cold → Coldness (This doesn't fit -er, so it should go under -ness)

#### -ness
- Kind → Kindness
- Cold → Coldness

#### -ment
- Publish → Publication

#### -y
- Bright → Brightly (Note: This is an adverb, not a noun. The correct noun would be "brightness.")

Explanation:

- -ation: Commonly used to form nouns from verbs or adjectives.
- -ion: Often used to form nouns from verbs.
- -er: Typically indicates a person who performs an action (e.g., teacher, driver).
- -ness: Used to form abstract nouns from adjectives (e.g., kindness, brightness).
- -ment: Often used to form nouns from verbs or adjectives.
- -y: Can form nouns from adjectives, but some may need adjustment (e.g., brightness).

This categorization helps understand how suffixes change the part of speech of words, specifically turning them into nouns.
