B

Block Editor (Gutenberg)
The modern WordPress content editor introduced in version 5.0. It uses a block-based approach where each piece of content (paragraph, image, heading) is a separate block that can be moved and customized independently.

C

Cache / Caching
A technique that stores static copies of your website pages to serve them faster to visitors. Caching significantly improves site speed and reduces server load.
CDN (Content Delivery Network)
A network of servers distributed globally that delivers your website's static files (images, CSS, JS) from the server closest to each visitor, improving load times.
CMS (Content Management System)
Software that allows you to create, manage, and modify website content without needing to write code. WordPress is the world's most popular CMS.
CSS (Cascading Style Sheets)
A styling language that controls how HTML elements look on a webpage — colors, fonts, spacing, and layout.

D

Dashboard
The WordPress admin area where you manage your entire website — from writing posts to installing plugins and changing settings.
DNS (Domain Name System)
The system that translates human-readable domain names (like google.com) into IP addresses that computers use to connect to servers.
Domain Name
Your website's unique address on the internet (e.g., wpguide.com). It's what users type into their browser to visit your site.

F

FTP (File Transfer Protocol)
A method for transferring files between your computer and your web server. Often used to manually upload themes, plugins, or troubleshoot WordPress issues.

G

Gutenberg
The code name for the block-based editor introduced in WordPress 5.0. See "Block Editor."

H

Hosting / Web Host
A service that stores your website files on a server and makes them accessible on the internet. Types include shared, VPS, dedicated, and managed WordPress hosting.
HTML (HyperText Markup Language)
The standard language for creating web pages. WordPress automatically generates HTML from your content, so you don't need to write it manually.
HTTP / HTTPS
HTTP is the protocol for transferring web pages. HTTPS is the secure version using SSL/TLS encryption. Always use HTTPS for security and SEO benefits.

P

Permalink
The permanent URL structure for your posts and pages. WordPress allows you to customize permalink formats (e.g., /blog/post-name/ vs /?p=123).
PHP
The server-side programming language that WordPress is built on. While you don't need to know PHP to use WordPress, understanding basics helps with customization.
Plugin
An add-on software package that extends WordPress functionality. Plugins can add contact forms, SEO tools, e-commerce features, security, and more.

R

Responsive Design
A web design approach that makes websites look and function well on all devices — desktops, tablets, and phones. Most modern WordPress themes are responsive by default.

S

SEO (Search Engine Optimization)
The practice of optimizing your website to rank higher in search engine results, driving more organic traffic.
Shortcode
A small piece of code enclosed in brackets like [gallery] that you can insert into posts to display dynamic content like galleries, forms, or embedded media.
SSL Certificate
A digital certificate that enables HTTPS and encrypts data between the visitor's browser and your server. Essential for security, trust, and SEO.

T

Theme
A collection of templates and stylesheets that define the visual appearance of your WordPress site. Thousands of free and premium themes are available.

W

Widget
A small content block that can be placed in widget-ready areas like sidebars and footers to display menus, recent posts, search bars, and more.
WordPress.org
The official website for free, open-source WordPress software. Download the software here and install it on your own hosting. Also home to the theme and plugin directories.
WordPress.com
A commercial hosting service by Automattic that runs WordPress software. Offers free and paid plans with varying levels of customization and control.
WYSIWYG
