No word processor on the Amiga is still supported. Except maybe Papayrus Office. It and AmigaWriter are probably the only ones you can still buy first-hand.
That being said, Wordworth7 and FinalWriter97 both suit my needs for basic documents. I've never tried to use them for anything terribly complicated, so I don't know how well they work in that respect.
As for Microsoft Word support, forget it. If you find anything that supports it, it'll probably be compatible with Word 97 at best. You can shuffle simple files back and forth in RTF format, though.
A more complicated solution is to use Antiword. It can convert Word docs to plain text (formatting not preserved), so you can do a one-way import. I think it can also convert to PostScript and PDF, but the 68K port may be too old to support those features.
Actually, I think the newest version of PageStream can edit PDFs. It might even be able to import Word docs directly, but it could be considered overkill for word processing. Check their
