I am looking for the right way to say something.

context: there is a job vacancy.

How would you ask whether that job vacancy is still "available" "in course" "on" or has been already "fullfilled" "given"?.

I don't know what words to use in this situation.

I would appreciate any help. Thank you in advance.

You're nearly there. I would say,"I wanted to enquire about the advertised job vacancy (for), is the job still available or has the post been filled?"
thank you so much again!

Your answer lies in your question itself.

I would say;

I am writting to make an inquiry regarding ---------position. I would be grateful if you could let me know whether the position is still available.


I'd like to inquire if you are still accepting applications?
