[Translation]s are resources that can be loaded and unloaded on demand. They map a collection of strings to their individual translations, and they also provide convenience methods for pluralization.

[Translation] maps a collection of strings to their individual translations, and also provides convenience methods for pluralization.
|
||||
A [Translation] consists of messages. A message is identified by its context and untranslated string. Unlike [url=https://www.gnu.org/software/gettext/]gettext[/url], using an empty context string in Godot means not using any context.
