In WordPress, a “plugin” is a software component that adds specific functionality to a WordPress website. It is a piece of code that can be installed and activated on a WordPress site to extend its features and capabilities beyond the core functionality provided by WordPress itself.
If you need any functionality that isn’t included in the WordPress default system or in your theme, you can use a plugin instead.
Plugins can be used to add new features such as contact forms, social media sharing buttons, e-commerce functionality, search engine optimization tools, and more. There are thousands of free and paid plugins available for WordPress, and they can be downloaded from the WordPress Plugin Repository or from third-party websites.
Plugins are designed to be easy to install and use. Once installed, a plugin can be activated from the WordPress dashboard, and its settings can be accessed and configured from the plugin’s own settings page.
