LyX (styled as ${\displaystyle \mathbf {L} \!{}_{\mathbf {\displaystyle Y} }\!\mathbf {X} }$; pronounced [ˈlɪks]) is an open source document processor based on the LaTeX typesetting system. Unlike most word processors, which follow the WYSIWYG ("what you see is what you get") paradigm, LyX has a WYSIWYM ("what you see is what you mean") approach, where what shows up on the screen roughly depicts the semantic structure of the page and is only an approximation of it.

Since LyX relies on the typesetting system of LaTeX without being a full-fledged LaTeX editor itself, it has the power and flexibility of LaTeX, and can handle documents including books, notes, theses, to academic papers, letters, etc. LyX's interface is structured so that while knowledge of the LaTeX markup language is not necessary for basic usage, new LaTeX directives can be added into the document to support more complex features during editing — though not at the level of full control a full-fledged LaTeX editor can afford.[2][3][4][5]

LyX is popular among technical authors and scientists for its advanced mathematical modes, though it is increasingly used by non-mathematically-oriented scholars as well[6][7] for its bibliographic database integration[8] and its ability to manage multiple files.[8] LyX has also become a popular publishing tool among self-publishers.[9][10]

LyX is available for various operating systems, including Windows, MacOS, Linux, UNIX, OS/2 and Haiku. LyX can be redistributed and modified under the terms of the GNU General Public License and is thus free software.

## History

Matthias Ettrich started developing a shareware program called Lyrix in 1995. It was then announced on Usenet, where it received a great deal of attention in the following years.

Shortly after the initial release, Lyrix was renamed to LyX due to a name clash with a word processor produced by the company Santa Cruz Operation.[14] The name LyX was chosen because of the file-suffix '.lyx' for Lyrix files.[15]
