Laravel - Localization - Overriding Package Language Files

Some packages may ship with their own language files. Instead of changing the package's core files to tweak these lines, you may override them by placing files in the resources/lang/vendor/{package}/{locale} directory.

So, for example, if you need to override the English translation strings in messages.php for a package named skyrim/hearthfire, you should place a language file at: resources/lang/vendor/hearthfire/en/messages.php. Within this file, you should only define the translation strings you wish to override. Any translation strings you don't override will still be loaded from the package's original language files.
