DefinitionHTML is a markup language (マークアップ言語) that describes the structure of a web page, such as headings, paragraphs and links, with tags (タグ; markers enclosed in "<" and ">").
ExplanationTo mark up text means to attach labels such as "this is a heading" to its parts to show their roles. A browser reads a file written in HTML and assembles the page on screen according to those labels. When a hyperlink is written in, readers can move from that page to another one.
AnalogyIt is like writing notes such as "main heading" or "photo here" in red in the margins of a manuscript, so the printer lays out the page exactly as marked.
Memory hookHyperText = text that links to other documents; Markup = adding marks. The name itself says "a language for marking up linked documents."
