Question My "read more" needs translation

I use Coraline theme and I've checked the WP codex for changing the "read more" link to the Spanish translation "leer mas." I don't get it. Please tell me exactly where to change php or whatever. In which edit? This would be an enormous help.

Thanks in advance.

While on the subject of changing code, I also want to delete a comment form (default) off of a contact sheet. I only want my readers to view the contact form when they click "Contact." How can I eliminate this?

look for this code or add it to functions.php

PHP:

// Puts link in excerpts more tag
function new_excerpt_more($more) {
      global $post;
    return '<a class="moretag" href="'. get_permalink($post->ID) . '"> Read the full article...</a>';
}
add_filter('excerpt_more', 'new_excerpt_more');

and to remove comments:
If yours theme has a custom contact page template ex. contact.php remove piece of code that is responsive for comments form if it hasn't - creat it
