Okay, keeping it VERY basic, Soniccc's idea will work, with some alterations:
create a new file at: /includes/languages/twist_of_nature/english.php
If you don't already have that folder and that file at that location, make one containing just the following code. If you *do* already have that , then simply add the following code (except the <?php line) to the end of it:
Code:
<?php
// custom label for category 18 and its subcats
if (isset($_GET['cPath']) && (int)$_GET['cPath'] == 18) {
define('TABLE_HEADING_NEW_PRODUCTS', 'New arrivals for %s');
}
You could add other defines normally found in the main english.php inside this "if" statement if you need to change things specifically for that category.
