In order to create a Multilingual Site, you have to use a translation plugin. Multilingual plugins offer WordPress users the ability to run a multilingual site with a single WP install.

- Support for both manual and automatic translation (via Google Translate)
- Ability to translate dynamic strings added by WordPress, plugins, and themes.
- An editorial control allows you to publish your language only when all your translations are done

It’s worth mentioning that the plugin does have a premium version that offers several add-ons which allow you to add unlimited languages, automatically detect a visitor’s language, display different navigation elements for different languages, and more.
