KWord is a free (GPL) word processor, member of the KOffice project of the KDE Desktop Environment.
Despite the name, KWord isn't meant simply as a clone of Microsoft Word. Although it is hoped in the future that KWord will support most of Word's features, in some important respects it is different. The text-layout scheme in KWord is based on frames, making it similar to Adobe PageMaker. These can be placed anywhere on the page, and can incorporate text, graphics and embedded objects. Each new page is a new frame, but the text is able to flow through KWord's ability to link frames together. The use of frames means that complicated graphical layouts can be achieved relatively easily in KWord.
