Markup language

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.
