How to delete/ remove translations manually

Hi, is it possible to delete/ remove a single translation/ language from a single page/ post? Example: I created a page in german, which is my default language. Now I clicked on the English tab, and created an English translation for the page. But things are changing and the site shall always show the German version, so when I open the page in another language it shall behave like there was no translation created for the page. I think it should be possible to delete the English translation, any help?
