Is inform the process correct grammar?

"Inform" is a verb, and verbs need an object to be grammatically correct. So, "inform" alone is not correct grammar.

Here are some examples of how to use "inform" correctly:

* "Inform me" (You are informing the speaker)

* "Inform the manager" (You are informing the manager)

* "Inform us about the changes" (You are informing "us" about the changes)

You need to specify who or what is being informed.
