When a suffix changes noun into verb said to change the of word?

When a suffix changes a noun into a verb, it is said to change the part of speech of the word.

Here's why:

* Part of speech refers to the grammatical function a word plays in a sentence.

* Nouns typically name people, places, things, or ideas.

* Verbs express actions or states of being.

Adding a suffix can change a word's function from naming something to describing an action or state.

Example:

* Noun: "gift"

* Verb (with suffix -ing): "gifting"

The suffix "-ing" turns the noun "gift" into the verb "gifting," which describes the action of giving a gift.
