Dictionary of WordPress – Terminology for Beginners to Advanced (K-Z)

WordPress has a lot of words that we hear a lot, but they’re not always clearly defined. To help with this, we’re continuing our dictionary of the most common WordPress terms for beginner and advanced users. This is part 2 which covers the letters K-Z.

Our goal is to make the terms understandable to anyone regardless of their skillset. The definitions will not be exhaustive. If we missed any terms that you’d like us to add, please let us know in the comments.

Be sure to check out part one, Dictionary of WordPress – Terminology for Beginners to Advanced (A-J).

K

Kernel – the core of the operating system. It’s not specifically a WordPress term, but I wanted to start with k.

L

Linux – an open source computer operating system based on UNIX. It’s highly stable and is the most popular OS for web servers.

Localhost – the computer you are currently using. It can be used to host a test and development installation of WordPress (using software such as WAMP or MAMP) that doesn’t live on the Internet.

Loop – sometimes called WordPress loop, is the code that displays posts. WordPress themes can be coded to display posts based on template tags.

M

Managed Hosting – hosting that’s optimized for WordPress. Its tools make WordPress easier to install, the site loads faster, has automatic backups and updates, and it includes security. For more information about managed hosting, see the article How To Choose The Best Hosting Service for Divi and WordPress.

Media – a tab in the WordPress dashboard where you can upload images, files, video, audio, etc. that can then be used in your posts. The tab includes the uploading area and the library where you can see media that has already been uploaded. It can also refer to the files themselves.

Media Settings – a sub-menu in the Media settings where you can specify the settings for media uploads.

Media Image Sizes – a feature in the Media tab in the Settings menu that allows you to choose the default sizes for all images that you upload to your website. Once you define your image sizes, WordPress automatically generates a copy for each size when the images are uploaded.

Memory Usage – the amount of memory used by a PHP script. The script can be coded into WordPress, themes, or plugins. Scripts that use too much memory can put a strain on the server and slow down the website.

Menu – navigation links that are usually placed in the header and footer. They link to the main pages of the website and sometimes include subpages to help organize the links.

Meta – refers to several things including the HTML tags used to define a web page to search engines, and information that’s associated with posts such as the date and author. It can also refer to a widget of links in the sidebar to log in.

Multisite (MU) – a network of WordPress sites under a single installation. The subdomains can be controlled by the primary domain. Each subdomain can have different themes and plugins but they must be installed on the primary domain. Each subdomain has an admin while the primary domain has a super-admin that’s in control of the subdomains.

MySQL – the open source database management system that WordPress uses to store and retrieve your blog content including pages, posts, images, comments, meta, etc.

N

Nameservers – the servers hosted by the domain registrar that translates the domain name to an IP address and vice versa. This is what allows us to enter a domain name into the address bar rather than the IP address.

Navigation – the links in the menu, content, buttons, and sidebars that redirect you to other pages on the website.

Nonce – a number or key that’s only used one time in order to protect forms from getting misused or hacked. The key is verified before the form is submitted. If the verifications fail, WordPress returns a 403 Forbidden response with the error message “Are you sure you want to do this?”

O

Open Source – software where the source code is open and available for anyone to study, use, change, and redistribute. This makes it easier for developers to make improvements, fix security issues, report bugs, and submit patches. WordPress is open source.

P

Page – the page post type with its own unique URL. Pages are used for common information that doesn’t change often. They’re not part of the blog loop. They can be hierarchal and have sub-pages. Common pages include the home page, About, Contact, Services, Terms and Conditions, etc.

Parent Theme – a theme that provides its functionality, features, and styling to a child theme. Developers can make changes to the child theme and the parent theme is not changed. When the parent theme updates, the changes are not lost. Our favorite parent theme is Divi.

Permalinks – the permanent URLs of your blog posts and pages. Permalinks for posts can include information such as the post title, date, categories, etc. You have control over the features of permalinks. The default permalink format just provides the post number.

Permissions – security settings that restrict or allow users to perform certain functions. Certain users can’t upload media, or publish and edit posts, etc.

PHP (originally Personal Home Page, now PHP: Hypertext Preprocessor) – a server-side open source scripting language that integrates with HTML. PHP code is processed on the webserver. When a browser asks for a PHP page, the PHP pre-processor creates HTML output to be displayed in the browser. WordPress was written in PHP.

Post Status – describes the publish status of a post, which determines who has access to see it. It can be a draft, auto-draft, pending (pending review by the admin), published, private, and trash.

Post Types – the various types of posts that can be created. Built-in post types include pages, posts, menus, attachments, and revisions. Other post types, called Custom Post Types, can be added manually, with themes, or with plugins. Popular custom post types include WooCommerce Products, LMS courses, projects, portfolios, recipes, etc.

Primary Menu – the main navigation menu of the website. It’s the menu that displays in the header by default and provides links to the pages of the site. You can create your own menu to include or exclude anything you want including pages, categories, custom links, posts, and custom post types.

Profile – the information about a registered user. It includes their name, nickname, preferred color scheme, contact info, etc. Custom post types add other settings including billing information.

For more information about hosting plans, see the article How To Choose The Best Hosting Service for Divi and WordPress.

Shortcodes – small tags that bring PHP code into your content. Rather than pasting in the code itself, you simply paste or select the shortcode that represents the full code. This makes code easier to use within your content.

Spam – any type of unwanted content that a website receives. It can be in the form of comments, pingbacks, user registrations, form content, etc. The content usually tries to sell a product, contains lots of links, links to unethical websites, includes malware, and more. Spam is usually handled through a spam-blocking plugin such as Akismet or a security plugin.

Splog – a spam blog created for the purpose of manipulating search engines and displaying ads. They often contain fake or stolen content stuffed with keywords.

SSL (Secure Sockets Layer) – the standard security protocol for encrypting the link between a server and the user’s browser. They’re used to secure transactions and protect information.

Subdomain – a domain that is a child of a parent, or primary, domain. The name of the subdomain is added to the front of the primary domain’s URL and it can be a different website. For example, the Aspen Grove Studios subdomain called test would have the URL test.aspengrovestudios.com. Subdomains are set up in the server’s cPanel.

Subscriber – a user role that can log in to the dashboard and create and maintain their profile. They can’t write, publish, or edit articles, but it does make it easier for them to leave comments.

T

Tag – a pre-defined taxonomy that helps describe a post. They’re more specific than a category. They’re most similar to keywords. They help you organize your posts and can be displayed in several ways. Users can click on tags and see posts with just those tags. They must be added to the posts manually, but there’s no limit to the number you can add.

Tagline – a short sentence that describes the website. It usually sits under the logo. Taglines are usually catchy phrases that can provide an easy way of showing the purpose of the site.

Term – a group or subset of a taxonomy. They have a title, slug, and a description.

Text Editor – there are two types of text editors. One is an editor that can edit files in plain text format. They can be used to write code. Plain text is preferred over word processors because they don’t add formatting to the code. Notepad, Notepad++, Coda, and similar text editors are popular for code. The other is the content editor for WordPress posts. The classic and Gutenberg editors have tabs for editing visually and in code.

Theme – the template of a WordPress website that the user sees in their browser. It’s the user interface and determines the sites’ layout, colors, interactivity, etc. Themes are made up of several files to create the look and feel of the site. Designers can create them and users can customize them. You can purchase them or install them from the WordPress directory. You can easily change from one theme to another.

Trash – post types such as comments, posts, and pages have a trash folder. When you delete them they appear in this folder for 30 days. You can restore them any time you want within the 30 days. After 30 days they are deleted from the database. You can empty the trash any time you want. Once you empty the trash the files are permanently deleted.

U

Update – official modifications to the WordPress core, themes, and plugins that increase their version level. When WordPress, themes, and plugins have an update available a notification is sent to your WordPress installation and you’re alerted that an update is available. Some updates require permissions, such as a subscription.

Upload – a file that’s uploaded to your WordPress website. They’re usually uploaded in the media screen. Not all users have permission to upload files.

URL (Uniform Resource Locator) – the address of a specific website or file. It’s the complete string that’s displayed in the address bar.

Visual Editor – the visual tab in both the classic rich text editor and in Gutenberg. Its goal is to show visually in the backend what your post will look like on the frontend.

VPS Hosting (Virtual Private Server) – a hosting plan where your website has a dedicated amount of resources and storage space. Other websites may be on the server, but they will never have access to your resources and space, so it’s virtually the same as having your own dedicated server. It’s more economical than dedicated servers. For more information about hosting plans, see the article How To Choose The Best Hosting Service for Divi and WordPress.

W

Widget – a piece of code that performs a function and is added to widget-ready areas such as sidebars. A widget can be just about anything including a calendar, login form, navigation menu, list of the most recent posts, photos, text, HTML, and lots more. Widgets are listed in the widget menu in the dashboard. You can drag and drop them where you want them within the widget areas.

Widget-ready Area – a pre-defined location within your theme’s layout that can display widgets. Some themes, such as Divi, add new widget areas. Some allow you to create your own widget areas.

WYSIWYG (What You See Is What You Get) – an editor that’s meant to display your content as you create it in the same that it will appear to your visitors. Gutenberg and the Divi Visual Builder are WYSIWYG editors.
