Is priority a noun or adjective?

Answer 1

The word 'priority' is a noun, a word for a concern, interest or desire that comes before all others; the person or thing that is regarded as more important than another; the precedence given to some before others; a word for a thing.

Note: Only one of seven dictionaries (+Google) consulted listed 'priority' as an adjective. That dictionary did not cite any basis for that listing. When the noun 'priority' is used as an adjective, it can be considered an attributive noun (noun adjunct); for example, a priority situation.
