Comment (by subrataemfluence):

 Thank you! https://codex.wordpress.org/Conditional_Tags is a very useful
 area to explore.

 Meanwhile I added the following function in functions.php which actually
 works, although probably this is not the correct way to go!

 {{{
 function get_excerpt($limit, $show_more = true) {
         $excerpt = explode(' ', get_the_excerpt(), $limit);
         if (count($excerpt)>=$limit) {
             array_pop($excerpt);
             $excerpt = implode(" ",$excerpt).'...';
         } else {
             $excerpt = implode(" ",$excerpt);
         }
         $excerpt = preg_replace('`\[[^\]]*\]`','',$excerpt);
         if($show_more)
             return $excerpt . '<a href="'.get_the_permalink().'"
 rel="nofollow"> [more]</a>';
         else
             return $excerpt;
     }
 }}}
