For word processing there's WordGrinder, which is in the repos for many distros (in Fedora: dnf install wordgrinder). Things like LaTeX and Groff are for typesetting, which I don't view as the same as word processing. WordGrinder is more like the classical DOS word processors (e.g. WordPerfect 5.1).
