A markup language is a modern system for annotating a document in a way that is syntactically distinguishable from the text. The idea and terminology evolved from the "marking up" of manuscripts, i.e., the revision instructions by editors, traditionally written with a blue pencil on authors' manuscripts. Examples are typesetting instructions such as those found in troff, TeX and LaTeX, or structural markers such as XML tags. Markup instructs the software displaying the text to carry out appropriate actions, but is omitted from the version of the text that is displayed to users. Some markup languages, such as HTML, have pre-defined presentation semantics, meaning that their specification prescribes how the structured data are to be presented; others, such as XML, do not. A widely-used markup language is HyperText Markup Language (HTML), one of the document formats of the World Wide Web. HTML, which is an instance of SGML (though, strictly, it does not comply with all the rules of SGML), follows many of the markup conventions used in the publishing industry in the communication of printed work between authors, editors, and printers.

List of well-known document mark-up languages
 HyperText Markup Language (HTML) – the original markup language that
was defined as a part of implementing World Wide Web, an ad hoc
defined language inspired by the meta format SGML and which inspired
many other markup languages.
 Extensible HyperText Markup Language (XHTML): HTML reformulated in
XML syntax.
 XHTML Basic – a subset of XHTML for simple (typically mobile,
handheld) devices. It is meant to replace WML, and C-HTML.
 XHTML Mobile Profile (XHTML MP) – a standard designed for mobile
phones and other resource-constrained devices.
 Mathematical Markup Language (MathML)
 Rich Text Format (RTF) – Microsoft format for exchanging documents
with other vendors' applications. (It is not really a markup language, as it
was never meant for intuitive and easy typing.[1][2])
 Scalable Vector Graphics (SVG)
 TeX, LaTeX – a format for describing complex type and page layout often
used for mathematics, technical, and academic publications.
 Extensible 3D (X3D)
Metalanguages
 Standard Generalized Markup Language (SGML) – a standard pattern for
markup languages to which HTML and DocBook adhere.
 Extensible Markup Language (XML) – a newer standard pattern for
markup languages; a restricted form of SGML that is intended to be
compatible with it.
