How many source and destination languages can be specified in a Mendix application?

In Mendix applications, the design for language support is structured to simplify localization. Each application can have one source language, which is the primary language used throughout the application, and only one destination language can be specified for display purposes. This setup allows developers to create a clear baseline for translation efforts while ensuring that users experience consistent interactions in the specified destination language.

Choosing one source language ensures that all texts, labels, and messages are consistently managed and maintained, which is particularly important when the application is being updated or localized for a new audience. By limiting the application to one destination language, it helps streamline the user experience, focusing on delivering content effectively in a single language context at a time, as opposed to overwhelming users with multiple language options simultaneously, which could lead to confusion.

While the other options suggest possibilities for having multiple source or destination languages, Mendix prioritizes clarity and simplicity in handling translations, which is best achieved through the one-to-one model of source and destination integration.
