A #CustomizeWoo student reached out for premium support in regard to “WooCommerce taxonomies”. The question was: How do I change the label “tag” into something else, for example “brand”? Well, this is how it’s done!
Please note that this does not change the “tag” permalinks (URL, slug, etc), but only the “Tags” label on the frontend, and only on the Single Product Page.

if ( is_product() && 'woocommerce' === $domain ) {
// This will only trigger on the WooCommerce single product page
$translation = ( 1 === $number ) ? str_ireplace( 'Tag:', 'Brand:', $translation ) : str_ireplace( 'Tags:', 'Brands:', $translation );
}
return $translation;
