Is agriculture a noun or verb?

"Agriculture" is primarily a noun. It refers to the practice of farming and the cultivation of land for crops and livestock.

However, it can also be used as a verb, meaning "to practice agriculture". For example:

* Noun: "Agriculture is a vital part of the economy."

* Verb: "They are agricultureing in the fertile valley."

The verb form is less common and often considered informal or awkward. It's more common to use phrases like "farm" or "cultivate" in place of "agriculture" when used as a verb.
