laravel - Eloquent get only one column as an array

Question

How to get only one column as one dimentional array in laravel 5.2 using eloquent?

I have tried:

$array = Word_relation::select('word_two')->where('word_one', $word_id)->get()->toArray();

but this one gives it as 2 dimentional array like:

array(2) {
      [0]=>
      array(1) {
        ["word_one"]=>
        int(2)
      }
      [1]=>
      array(1) {
        ["word_one"]=>
        int(3)
      }
    }

but I want to get it as:

array(2) {
    [0]=>2
    [1]=>3
}

Word_relation::where('word_one', $word_id)->pluck('word_two')->toArray();
