How do I write this code to not show default on label_submit?

I researched the WordPress Codex some more and analyzed the code I posted here and if you look at the top where it says $form_args, but then in comment_form($forms_args):

<?php
        $form_args = array(
                'label_submit'          => 'Send',
                'title_reply'           => 'Write a Reply or Comment',
                'comment_notes_after'   => '',
                'comment_field'         => '<p class="comment-form-comment"><label for="comment">'._x('Comment','noun').'</label><br /><textarea id="comment" name="comment" cols="45" rows="8" aria-required="true"></textarea></p>',
        );

        comment_form($forms_args);
   ?>

So I just needed to remove the s from what I passed into comment_form:

<?php
        $form_args = array(
                'label_submit'          => 'Send',
                'title_reply'           => 'Write a Reply or Comment',
                'comment_notes_after'   => '',
                'comment_field'         => '<p class="comment-form-comment"><label for="comment">'._x('Comment','noun').'</label><br /><textarea id="comment" name="comment" cols="45" rows="8" aria-required="true"></textarea></p>',
        );

        comment_form($form_args);
