Example 1: laravel Route::group definition

Route::group(['prefix'=>'accounts','as'=>'account.'], function(){
    Route::get('/', 'AccountController@index')->name('index');
    Route::get('connect', 'AccountController@connect')->name('connect');
});

Route::group(['prefix'=>'quotes','as'=>'quote.'], function(){
    Route::get('/', 'QuoteController@index')->name('index');
    Route::get('connect', 'QuoteController@create')->name('create');
});

Example 2: laravel group routes

Route::group(['prefix' => 'admin'], function () {
    Route::get('users', function ()    {
        // Matches The "/admin/users" URL
    });
});

Example 3: laravel route namespace and prefix

Route::name('admin.')->group(function () {
    Route::get('/users', function () {
        // Route assigned name "admin.users"...
    })->name('users');
});

use App\Models\User;

Route::get('/users/{user}', function (User $user) {
    return $user->email;
});
