AbiWord is a free software word processor. The name "AbiWord" (pronounced "Abby Word") is derived from the root of the Spanish word "abierto", meaning "open". It currently runs on Linux, Mac OS X (PowerPC), Microsoft Windows, ReactOS, BeOS (unsupported), AmigaOS 4.0 (through its Cygnix X11 engine), and other operating systems.
AbiWord was originally started by SourceGear Corporation as the first component of AbiSuite, as part of a plan to create a full Office Suite that would be free software. However, SourceGear gradually moved on to other business interests, and now the AbiWord project is run by a team of volunteer developers. AbiWord is part of GNOME Office, a collection of office applications with some degree of integration.
