Preferred Languages is a WordPress plugin designed to improve the multilingual experience on websites. It allows users to select multiple languages for their site, creating a fallback chain that ensures translations are displayed in the preferred order. This is particularly beneficial for non-English speakers, as it minimizes instances where content reverts to the original English strings due to missing translations. The plugin also supports keyboard shortcuts for easy management of language preferences, enhancing user efficiency.

In addition to its core functionality, Preferred Languages offers the option to merge incomplete translations, which can prevent English strings from appearing when translations are not fully available. This feature is enabled by default on WordPress 6.5 and newer versions, while users on older versions are advised to use it judiciously. Active development on this plugin is ongoing, with opportunities for community involvement available through GitHub.
