Is there a free word program that would take the place of microsoft word?

My “trial version” of microsoft word has expired therefore I can no longer use it. Being as there is practically a free version of everything on the internet I was wondering if there was a free word program. I am a college student and paying a hundred dollars for anything is hard to do.

word program

Thank you very much for any help.
