Change “Shipping” text to “Delivery” everywhere I appears in woocommerce

You can use custom functions.php file inside your theme folder. If a file named functions.php already exist, then you can use the following formulae. You can also create a functions.php file by yourself in the theme root folder if it does not exist.

<?php
/*
Functions.php file
Description: Site specific codes and functions
*/

function fix_woocommerce_strings( $translated, $text, $domain ) {

    // STRING 1
    $translated = str_ireplace( 'Shipping', 'Delivery', $translated );


    return $translated;
    }


    add_filter( 'gettext', 'fix_woocommerce_strings', 999, 3 );

//EOF
?>
