In Wordpress “the_Excerpt()” displays the excerpt filed value of the current post with [...] at the end, which is not a “read more” link. If you do not provide an explicit excerpt to a post (in the post editor’s optional excerpt field), it will display a teaser which refers to the first 55 words of the post’s content.

By default, if you have your theme set to display the excerpt and nothing is entered, WordPress will just display the full text instead. If you want don’t want anything displayed then simply place the following code wherever you want the excerpt to appear (or not)

<?php if(!empty($post->post_excerpt)) {the_excerpt(); } ?>
