High Quality Content by WIKIPEDIA articles! AbiWord is a free and open source software word processor. It was originally started by SourceGear Corporation as the first part of a proposed AbiSuite. Development stopped when SourceGear changed their focus to Internet appliances. AbiWord was adopted by some open source developers and AbiWord continued to be developed. The name "AbiWord" (pronounced , like the name, "Abby" + ) is derived from the root of the Spanish word "abierto", meaning "open". It runs on Linux, Microsoft Windows, ReactOS, Solaris, AmigaOS 4.0 (through its Cygnix X11 engine), and other operating systems. However, the Mac OS X port has remained on version 2.4 since 2005, although the current version does run non-natively on Mac OS X through X11.app. AbiWord is part of the AbiSource project which develops a number of office-related technologies.
