多くのソフトウェアパッケージ同様、 WordPress は独自の専門語や独自語を持ちています。この記事では、 WordPress で用いられるいくつかの専門用語を紹介しましょう。

WordPress は[開発者達]によって、 ウェブログ またはブログ用ソフトウェアとして作られました。「ブログ」とは、用語集にまとめられているように、個人または複数の人々が公開するオンラインの日記または連続する一連の記事を指します。多くの ブログ は本質的に個人的なものであり、作者の意見や興味を反映するものです。しかし ブログ はニュース、ビジネス、政治、エンターテイメントの世界で重要なツールとなってきています。

ブログ とは コンテンツマネージメントシステム (CMS) の一種で、 Wikipedia には、「Webコンテンツを構成するテキストや画像などのデジタルコンテンツを統合・体系的に管理し、配信など必要な処理を行うシステムの総称」とあります。 ブログCMSウェブサイト (略して「サイト」) としての役割を果たします。 ウェブサイト は特定の目的、サービス、製品に関する記事や情報を集めたもので、オーナー個人の意見を反映するものではないと考えられています。近年では、 WordPress の役割が拡張したことから、 WordPress の開発者はブログのことを、 サイト というより一般的な呼び方をするようになってきました。

The term Word in WordPress refers to the words used to compose posts. Posts are the principal element (or content) of a blog. The posts are the writings, compositions, discussions, discourses, musings, and, yes, the rantings of the blog's owner and guest authors. Posts, in most cases, are the reason a blog exists; without posts, there is no blog!

To facilitate the post writing process, WordPress provides a full featured authoring tool with modules that can be moved, via drag-and-drop, to fit the needs of all authors. The Dashboard QuickPress module makes it easy to quickly write and publish a post. There's no excuse for not writing.

Integral to a blog are the pictures, images, sounds, and movies, otherwise know as media. Media enhances, and gives life to a blog's content. WordPress provides an easy to use method of inserting Media directly into posts, and a method to upload Media that can be later attached to posts, and a Media Manager to manage those various Media.

An important part of the posting process is the act of assigning those posts to categories. Each post in WordPress is filed under one or more categories. Categories can be hierarchical in nature, where one category acts as a parent to several child, or grandchild, categories. Thoughtful categorization allows posts of similar content to be grouped, thereby aiding viewers in the navigation, and use of a site. In addition to categories, terms or keywords called tags can be assigned to each post. Tags act as another navigation tool, but are not hierarchical in nature. Both categories and tags are part of a system called taxonomies. If categories and tags are not enough, users can also create custom taxonomies that allow more specific identification of posts or pages or custom post types.

In turn, post categories and tags are two of the elements of what's called post meta data. Post meta data refers to the information associated with each post and includes the author's name and the date posted as well as the post categories. Post meta data also refers to Custom Fields where you assign specific words, or keys, that can describe posts. But, you can't mention post meta data without discussing the term meta.

Generally, meta means "information about"; in WordPress, meta usually refers to administrative-type information. So, besides post meta data, Meta is the HTML tag used to describe and define a web page to the outside world, like meta tag keywords for search engines. Also, many WordPress-based sites offer a Meta section, usually found in the sidebar, with links to login or register at that site. And, don't forget Meta Rules: The rules defining the general protocol to follow in using this Codex, or Meta, as in the MediaWiki namespace that refers to administrative functions within Codex. That's a lot of Meta!

After a post is made public, a blog's readers will respond, via comments, to that post, and in turn, authors will reply. Comments enable the communication process, that give-and-take, between author and reader. Comments are the life-blood of most blogs.

Finally, WordPress also offers two other content management tools called Pages and custom post types. Pages often present static information, such as "About Me", or "Contact Us", Pages. Typically "timeless" in nature, Pages should not be confused with the time-oriented objects called posts. Interestingly, a Page is allowed to be commented upon, but a Page cannot be categorized. A custom post type refers to a type of structured data that is different from a post or a page. Custom post types allow users to easily create and manage such things as portfolios, projects, video libraries, podcasts, quotes, chats, and whatever a user or developer can imagine.

The flexibility of WordPress is apparent when discussing terminology related to the design of a WordPress blog. At the core of WordPress, developers created a programming structure named The Loop to handle the processing of posts. The Loop is the critical PHP program code used to display posts. Anyone wanting to enhance and customize WordPress will need to understand the mechanics of The Loop.

Along with The Loop, WordPress developers have created Template Tags which are a group of PHP functions that can be invoked by designers to perform an action or display specific information. It is the Template Tags that form the basis of the Template Files. Templates (files) contain the programming pieces, such as Template Tags, that control the structure and flow of a WordPress site. These files draw information from your WordPress MySQL database and generate the HTML code which is sent to the web browser. A Template Hierarchy, in essence the order of processing, dictates how Templates control almost all aspects of the output, including Headers, Sidebars, and Archives. Archives are a dynamically generated list of posts, and are typically grouped by date, category, tag, or author.

Templates and Template Tags are two of the pieces used in the composition of a WordPress Theme. A Theme is the overall design of a site and encompasses color, graphics, and text. A Theme is sometimes called the skin. With the recent advances in WordPress, Theme Development is a hot topic. WordPress-site owners have available a long list of Themes to choose from in deciding what to present to their sites' viewers. In fact, with the use of a Theme Switcher Revisited Plugin, WordPress designers can allow their visitors to select their own Theme.

As the capabilities of WordPress have improved, developers have added tools that allow users to easily manage a site's look and functionality:

  • Widgets provide an easy way to add little programs, such as the current weather, to a sidebar.
  • Menus make it easy to define the navigation buttons that are typically present near the top of a site's pages.
  • The Background tool allows the user to change the background image and color of a site.
  • The Header tool gives the user control of the images displayed at the top of a site's various pages.
  • Formats allow the user to control the display of a specific post (i.e. display this post as an Aside or as a quote or as a gallery). The WordPress Twenty Seventeen テーマ is an excellent example of a theme that uses these tools.

And speaking of the WordPress Twenty Seventeen テーマ, developers and users are encouraged to explore that theme in detail. The WordPress Twenty Seventeen テーマ, developed by the WordPress community, demonstrates the use of tools such as Menus and Widgets, provides examples of recommended theme coding techniques, and emphasizes the use of the Child Theme concept to shield a theme from getting overwritten during a WordPress update.

Plugins are custom functions created to extend the core functionality of WordPress. The WordPress developers have maximized flexibility and minimized code bloat by allowing outside developers the opportunity to create their own useful add-on features. As evidenced by the Plugin Directory, there's a Plugin to enhance virtually every aspect of WordPress. A Plugin management tool makes it extremely easy to find and install Plugins.


Another set of terms to examine are those involving the Administration of a WordPress site. A comprehensive set of Administration Panels enables users to easily administer and monitor their blog. A WordPress administrator has a number of powers which include requiring a visitor to register in order to participate in the blog, who can create new posts, whether comments can be left, and if files can be uploaded to the blog. An Administrator also defines Links and the associated Link Categories which are an important part of a blog's connection to the outside world.

Some of the main administrative responsibilities of a WordPress blog involve adding, deleting, and managing Registered Users. Administering users means controlling Roles and Capabilities, or permissions. Roles control what functions a registered user can perform as those functions can range from just being able to login at a blog to performing the role administrator.

Another chief concern for the blog administrator is Comment Moderation. Comments, also called discussions, are responses to posts left for the post author by the visitor and represent an important part of "the give and take" of a blog. But Comments must be patrolled for Spam and other malicious intentions. The WordPress Administration Comments SubPanel simplifies that process with easy-to-use screens which add, change, and delete Comments.

And not to be forgotten is the obligation for an administrator to keep their WordPress current to insure that the latest features, bugs, and security fixes are in effect. To accomodate administrators, WordPress has a simple Upgrade Tool to download and install the lastest version of WordPress. There's no excuse to not upgrade!


The final set of jargon relates to helping you with WordPress. First and foremost is the hanging Help tab that is displayed under each of the Administration SubPanels. That contextual help describes the function and use of the current SubPanel and provides links to other help topics. And, there are other help resources available to WordPress users; Getting More Help, Finding WordPress Help, Troubleshooting, and WordPress FAQ (frequently asked questions) are good starting points. Also Getting Started with WordPress will jump-start readers into the world of WordPress and the excellent WordPress Lessons provide in-depth tutorials on many of the aspects of using WordPress. Among the most important resources is the WordPress Support Forum where knowledgeable volunteers answer your questions and help solve any problems related to WordPress. And, of course, this Codex which is filled with hundreds of articles designed to make your WordPress experience a success!

WordPress という名前の歴史

WordPress の技術的な専門用語以外に、 WordPress という名前の歴史を知ることも興味深いものがあります。 "WordPress" という名前は[[1]]である Matthew Mullenweg の印刷機 (printing press) 的なソフトウェアプロジェクトへの要望に対して、 Christine Selleck の回答として作りだされました (関連記事はこちら) 。ここでの press とはレポーター、ジャーナリスト、コラムニスト、写真家の世界を意味するものです。ユーザー自身の言葉 (Word) を発信することをための印刷機 (printing press) としての役割を果たすことから、 "WordPress" が最適な名前として選ばれました。
