i am using the News system (news) extension. In the listing view I need to translate the "read more" text to my local language (german). I already found the translation file inside the plugins folder.
Path: /typo3conf/ext/news/Resources/Private/Language
Now I need to know if I just can overwrite this file or if I need to add my own translation file so the plugin is still perfectly updatable (and if so how does it work).
One easy way to do this is using the lfeditor extension https://extensions.typo3.org/extension/lfeditor/
read carefully the instructions about the editing modes!
Another possibility could be using TypoScript to override the labels - see https://docs.typo3.org/typo3cms/TyposcriptReference/Setup/Plugin/Index.html#local-lang-lang-key-label-key
