The writer uses [[Markup language|markup]] tagging conventions to define the general structure of a document, to stylise text throughout a document (such as bold and italics), and to add [[citation]]s and [[cross-reference]]s. A [[TeX]] distribution such as [[TeX Live]] or [[MiKTeX]] is used to produce an output file (such as [[PDF]] or [[Device independent file format|DVI]]) suitable for printing or [[digital distribution]].

LaTeX is widely used in [[academia]] for the communication and publication of scientific documents in many fields.<ref>{{Cite web |title=What are TeX, LaTeX and friends? |url=//www.ctan.org/what_is_tex.html}}</ref><ref name="Gaudeul2006">{{Cite journal |last=Alexia Gaudeul |date=June 2007 |title=Do Open Source Developers Respond to Competition?: The (La)TeX Case Study |journal=Review of Network Economics |volume=6 |issue=2 |doi=10.2202/1446-9022.1119 |s2cid=201097782 |doi-access=free}}</ref> It also has a prominent role in the preparation and publication of books and articles that contain complex [[Multilingualism|multilingual materials]], such as [[Arabic]] and [[Greek language|Greek]].<ref>{{Cite web |last=Markin |first=Pablo |date=1 November 2017 |title=LaTeX, Open Source Software, Facilitates the Adoption of Open Access by Authors, Repositories and Journals |url=http://openscience.com/latex-open-source-software-facilitates-the-adoption-of-open-access-by-authors-repositories-and-journals/ |access-date=5 November 2017 |website=OpenScience}}</ref> LaTeX uses the [[TeX]] [[typesetting]] program for formatting its output, and is itself written in the TeX [[Macro (computer science)|macro]] language.

LaTeX can be used as a standalone document preparation system, or as an intermediate format. In the latter role, for example, it is sometimes used as part of a pipeline for translating [[DocBook]] and other [[XML]]-based formats to [[PDF]]. The typesetting system offers programmable [[desktop publishing]] features and extensive facilities for automating most aspects of typesetting and desktop publishing, including numbering and cross-referencing of tables and figures, chapter and section headings, graphics, page layout, indexing and [[bibliography|bibliographies]].

Like TeX, LaTeX started as a writing tool for mathematicians and computer scientists, but even from early in its development, it has also been taken up by scholars who needed to write documents that include complex math expressions or non-Latin scripts,<ref>{{Cite news |title=Multilingual typesetting on Overleaf using babel and fontspec |language=en |url=https://www.overleaf.com/learn/latex/Multilingual_typesetting_on_Overleaf_using_babel_and_fontspec |access-date=2022-04-09}}</ref> such as [[Arabic script|Arabic]], [[Devanagari]] and [[Chinese characters|Chinese]].<ref>{{Cite web |title=Chinese |url=https://www.overleaf.com/learn/latex/Chinese |access-date=2020-12-30 |website=www.overleaf.com |language=en}}</ref>

LaTeX is intended to provide a high-level, descriptive markup language that accesses the power of TeX in an easier way for writers. In essence, TeX handles the layout side, while LaTeX handles the content side for document processing. LaTeX comprises a collection of TeX [[Macro (computer science)|macros]] and a program to process LaTeX documents, and because the plain TeX formatting commands are elementary, it provides authors with ready-made commands for formatting and layout requirements such as chapter headings, footnotes, cross-references and bibliographies.

LaTeX was originally written in the early 1980s by [[Leslie Lamport]] at [[SRI International]].<ref>{{Cite web |last=Leslie Lamport |date=April 23, 2007 |title=The Writings of Leslie Lamport: LaTeX: A Document Preparation System |url=//research.microsoft.com/users/lamport/pubs/pubs.html#latex |access-date=2007-04-27 |website=Leslie Lamport's Home Page}}</ref> The current version is LaTeX2e (stylised as {{stylized LaTeX|2}}), first released in 1994 but incrementally updated starting in 2015.

==History==
LaTeX was created in the early 1980s by [[Leslie Lamport]] when he was working at [[SRI International|SRI]]. He needed to write TeX macros for his own use and thought that with a little extra effort, he could make a general package usable by others. Peter Gordon, an editor at [[Addison-Wesley]], convinced him to write a LaTeX user's manual for publication (Lamport was initially skeptical that anyone would pay money for it);<ref name="Lamport2018">{{Cite web |last=Lamport |first=Leslie |date=23 August 2018 |title=My Writings |url=http://research.microsoft.com/en-us/um/people/lamport/pubs/pubs.pdf |access-date=5 September 2018 |pages=48–49}}</ref> it came out in 1986<ref name="Lamport1986"/> and sold hundreds of thousands of copies.<ref name="Lamport2018"/> Meanwhile, Lamport released versions of his LaTeX macros in 1984 and 1985. On 21 August 1989, at a TeX Users Group (TUG) meeting at Stanford, Lamport agreed to turn over maintenance and development of LaTeX to [[Frank Mittelbach]]. Frank Mittelbach, along with Chris Rowley and Rainer Schöpf, formed the LaTeX3 team; in 1994, they released LaTeX2e, the current standard version. LaTeX3 has since been cancelled with features intended for that version being back-ported to LaTeX2e since 2018.<ref name="Latex3planning"/>

==Typesetting system==
LaTeX attempts to follow the design philosophy of [[Separation of presentation and content|separating presentation from content]], so that authors can focus on the content of what they are writing without attending simultaneously to its visual appearance. In preparing a LaTeX document, the author specifies the logical structure using simple, familiar concepts such as ''chapter'', ''section'', ''table'', ''figure'', etc., and lets the LaTeX system handle the formatting and layout of these structures. As a result, it encourages the separation of the layout from the content — while still allowing manual typesetting adjustments whenever needed. This concept is similar to the mechanism by which many [[word processor]]s allow styles to be defined globally for an entire document, or the use of [[Cascading Style Sheets]] in styling HyperText Markup Language ([[HTML]]) documents.

The LaTeX system is a [[markup language]] that handles typesetting and rendering,<ref>The design of LaTeX owes something to earlier markup systems such as [[Scribe (markup language)|Scribe]].</ref> and can be arbitrarily extended by using the underlying [[macro language]] to develop custom macros such as new environments and commands. Such macros are often collected into ''packages,'' which could then be made available to address some specific typesetting needs such as the formatting of complex mathematical expressions or graphics (e.g., the use of the <code>align</code> environment provided by the <code>amsmath</code> package to produce aligned equations).

To create a document in LaTeX, a user first creates a file, such as <code>document.tex</code>, typically using a [[text editor]]. The user then gives their <code>document.tex</code> file as input to the TeX program (with the LaTeX macros loaded), which prompts TeX to write out a file suitable for onscreen viewing or printing.<ref>PDF output is common, but TeX can output other formats such as DVI ("Device independent" format). See below for more detail about outputs.</ref> This write-format-preview cycle is one of the chief ways in which working with LaTeX differs from the [[WYSIWYG|What-You-See-Is-What-You-Get]] (WYSIWYG) style of document editing. It is similar to the code-compile-execute cycle known to computer programmers. Today, many LaTeX-aware editing programs make this cycle a simple matter through the pressing of a single key, while showing the output preview on the screen beside the input window. Some online LaTeX editors even automatically refresh the preview,<ref>{{Cite web |title=Overleaf |url=//www.overleaf.com}}</ref><ref>{{Cite web |title=Seeveeze |url=//www.seeveeze.com/}}</ref><ref>{{Cite web |title=LaTeX Base |url=//latexbase.com}}</ref> while other online tools provide incremental editing in-place, mixed in with the preview in a streamlined single window.<ref>{{Cite web |title=Authorea |url=//www.authorea.com/}}</ref>

==How it works==
The example below shows the input to LaTeX and the corresponding output from the system:

  \LaTeX{} is a document preparation system for
  the \TeX{} typesetting program. It offers
  programmable desktop publishing features and
  extensive facilities for automating most
  aspects of typesetting and desktop publishing,
  including numbering and cross-referencing,
  tables and figures, page layout,
  bibliographies, and much more. \LaTeX{} was
  originally written in 1984 by Leslie Lamport
  and has become the dominant method for using
  \TeX; few people write in plain \TeX{} anymore.
  The current version is \LaTeXe.

==Pronouncing and writing "LaTeX"==
[[File:LaTeX logo.svg|thumb|100px|The LaTeX wordmark, typeset with LaTeX's <code>\LaTeX</code> macro]]
{{main|TeX#Pronunciation and spelling}}
The characters 'T', 'E', and 'X' in the name come from the [[Greek alphabet|Greek]] [[capital letter]]s [[tau]], [[epsilon]], and [[chi (letter)|chi]], as the name of [[TeX]] derives from the {{lang-grc|τέχνη}} ('skill', 'art', 'technique'); for this reason, TeX's creator [[Donald Knuth]] promotes its pronunciation as {{IPAc-en|t|ɛ|x}} ({{respell|tekh}})<ref>Donald E. Knuth, ''The TeXbook'', Addison–Wesley, Boston, 1986, p. 1.</ref> (that is, with a [[voiceless velar fricative]] as in Modern Greek, similar to the ch in [[loch]]). Lamport remarks that "TeX is usually pronounced ''tech'', making ''lah''-tech, lah-''tech'', and ''lay''-tech the logical choices; but language is not always logical, so ''lay-tecks'' is also possible."<ref>Lamport (1994), p 5</ref>

The name is printed in running text with a typographical [[logo]]: {{stylized LaTeX}}.
In media where the logo cannot be precisely reproduced in running text, the word is typically given the unique capitalization ''LaTeX''. Alternatively, the TeX, LaTeX<ref>{{Cite web |last=O'Connor |first=Edward |title=TeX and LaTeX logo POSHlets |url=http://edward.oconnor.cx/2007/08/tex-poshlet |archive-url=https://web.archive.org/web/20071011230511/http://edward.oconnor.cx/2007/08/tex-poshlet |archive-date=2007-10-11 |access-date=2008-04-21}}</ref> and [[XeTeX]]<ref>{{Cite web |last=Taraborelli |first=Dario |title=CSS-driven TeX logos |url=http://nitens.org/taraborelli/texlogo |archive-url=https://web.archive.org/web/20170901040149/http://nitens.org/taraborelli/texlogo |archive-date=2017-09-01 |access-date=2008-04-21}}</ref> logos can also be rendered via pure [[CSS]] and [[XHTML]] for use in graphical [[web browser]]s — by following the specifications of the internal <code>\LaTeX</code> macro.<ref>{{Cite journal |last=Walden |first=David |date=2005-07-15 |title=Travels in TeX Land: A Macro, Three Software Packages, and the Trouble with TeX |url=//www.tug.org/pracjourn/2005-3/walden-travels/ |journal=The PracTeX Journal |issue=3 |access-date=2008-04-21}}</ref>

==Related software==
As a macro package, LaTeX provides a set of macros for TeX to interpret. There are many other macro packages for TeX, including Plain TeX, [[GNU Texinfo]], [[AMSTeX]], and [[ConTeXt]].

When TeX "compiles" a document, it follows (from the user's point of view) the following processing sequence: Macros → TeX → Driver → Output. Different implementations of each of these steps are typically available in TeX distributions. Traditional TeX will output a [[DVI (file format)|DVI]] file, which is usually converted to a [[PostScript]] file. 2000, Hàn Thế Thành and others have written a new implementation of TeX called [[pdfTeX]], which also outputs to [[PDF]] and takes advantage of features available in that format.<ref>{{Cite web |title=pdfTeX - TeX Users Group |url=https://www.tug.org/applications/pdftex/ |access-date=2019-07-20 |website=www.tug.org}}</ref> The [[XeTeX]] engine developed by Jonathan Kew, on the other hand, merges modern font technologies and Unicode with TeX.<ref>{{Cite web |title=XeTeX - TeX Users Group |url=http://www.tug.org/xetex/ |access-date=2019-07-20 |website=www.tug.org}}</ref> [[LuaTeX]] is an extended version of pdfTeX using Lua as an embedded scripting language.<ref name=luatex>{{cite web|
url=https://www.luatex.org/ | title=LuaTeX | access-date=2023-07-18}}</ref>

There are also many editors for LaTeX, some of which are offline, source-code-based while others are online, partial-WYSIWYG-based. For more, see [[Comparison of TeX editors]].

==Compatibility and converters==
LaTeX documents (<code>*.tex</code>) can be opened with any text editor. They consist of plain text and contain no hidden formatting codes or binary instructions. Also, TeX documents can be shared by rendering the LaTeX file to [[Rich Text Format]] (<code>*.rtf</code>), [[XML]], or the {{code|.cls}} container format.<ref name="Elsevier-LaTeX">{{Cite web |date=2015-05-11 |title=Latex Instructions |url=http://www.elsevier.com/authors/policies-and-guidelines/latex-instructions |access-date=2021-10-06 |website=[[Elsevier]]}}</ref> This can be done using the free software programs LaTeX2RTF or [[TeX4ht]]. LaTeX can also be rendered to PDF files using the LaTeX extension pdfLaTeX. LaTeX files containing Unicode text can be processed into PDFs with the <code>inputenc</code> package, or by the TeX extensions XeLaTeX and LuaLaTeX.

== Licensing ==
LaTeX is typically distributed along with plain [[TeX]] under a [[free software license]]: the [[LaTeX Project Public License]] (LPPL).<ref>{{Cite web |title=The LaTeX project public license |url=https://www.latex-project.org/lppl/ |access-date=2019-07-20 |website=www.latex-project.org}}</ref> The LPPL is not [[License compatibility|compatible]] with the [[GNU General Public License]], as it requires that modified files must be clearly differentiable from their originals (usually by changing the filename); this was done to ensure that files that depend on other files will produce the expected behavior and avoid [[dependency hell]]. The LPPL is [[Debian Free Software Guidelines]] (DFSG) compliant as of version 1.3. As [[free software]], LaTeX is available on most operating systems, which include [[Unix]] ([[Oracle Solaris|Solaris]], [[HP-UX]], [[AIX]]), [[BSD]] ([[FreeBSD]], [[macOS]], [[NetBSD]], [[OpenBSD]]), [[Linux]] ([[Red Hat Enterprise Linux|Red Hat]], [[Debian]], [[Arch Linux|Arch]], [[Gentoo Linux|Gentoo]]), [[Microsoft Windows|Windows]], [[DOS]], [[RISC OS]], [[AmigaOS]], and [[Plan 9 from Bell Labs|Plan 9]].
