Is information a noun, verb or adjective? Or is it also a noun and verb adjective?

"Information" is a noun, but in use, someone once sent such a short message: "If you have something, please inform me." This shows that someone has used it as a verb. But this usage is not universal enough to add a new part of speech to "information". In addition, although there are usages such as "information technology" and "information society", the word "information" here is an attribute, not an adjective. Therefore, "information" is just a noun.
