I highly recommend the following word processors because they’re simple, easy to use and user friendly. All are compatible with either Windows, Linux or Mac OSX:
Jarte is based on WordPad. There is a free option and then a paid option (that gives users more functionality). The free version is more than adequate for your word processing needs. I first discovered Jarte in 2010 and have used it ever since. The layout is simple and easy to understand. Features include Windows compatibility, an ergonomic tabbed interface, built in spell-check and fast loading time.
Apache OpenOfficeWriter (OpenOffice.org) is a Windows-based word processor that also supports Microsoft Word documents, handles cell-dependent calculations, and spell checks your work. Writer is included with the OpenOffice suite, which contains tools for creating word documents, graphics, presentations, spreadsheets, database and other common file types.
AbiWord is a Windows, Linux and MacOSX based word processing platform very similar to Microsoft Word. It is a full cross-platform application and has compatibility with not only Microsoft Word but also OpenOffice.org, Word Perfect and Palm OS.
Google Drive/Docs is web-based, meaning it can be used from any browser and operating system. It’s fully compatible with MS Word and is a suite with a variety of products very similar to MS Word. I’ve been using Google Drive/Docs for several years and find it much easier and more user friendly than MS Word. QuickOffice has been merged with Google Docs so opening and editing Word documents will be no problem.
