If you'd like to stop supporting a language, we recommend you disable rather than remove it. That way, you can keep up with translations in case you re-enable it.
To stop supporting a language:
From your service desk project, go to Project settings () > Language support.
Find the language's entry in the Translations table.
In the Visible to customers column, toggle the slider off.
As a result of disabling a language, customers whose preferred language is no longer supported will see the portal text in their preferred language (for example, Log in or Profile), and the service desk project request types and notifications in the service desk project default language.
