How to not define all routes for default language?

[Azoruk]

I want to translate ALL my routes on my website. My default language is EN, but I want to add French. Take the 'about' route for example.

Route::group(['prefix' => LaravelLocalization::setLocale(),
              'middleware' => [ 'localize' ]], function () {

    Route::get(LaravelLocalization::transRoute('routes.about'), ['as' => 'about', function () {
        return view('pages/about');
    }]);

});

Translation:

<?php
// resources/lang/en/routes.php
return [
    "about"    =>  "about",
];

<?php
// resources/lang/fr/routes.php
return [
    "about"    =>  "apropos",
];

I don't like that I have to translate "about" in English. I have hundreds of routes. If I don't translate the english default, it will return the URL "routes.about".
