What part of speech is purpose?

"Purpose" can be a few different parts of speech depending on how it's used:

* Noun: This is the most common use. It refers to the reason or aim of something.

* Example: "The purpose of this meeting is to discuss the project."

* Adjective: This is less common, but it means "having a specific aim or intention."

* Example: "He was a purposeful leader with a clear vision."

* Verb: This is very rare, but it means "to intend or mean."

* Example: "I purpose to finish this task by tomorrow."

So, without context, it's impossible to say definitively what part of speech "purpose" is. You need to look at how it's used in a sentence to determine its function.
