You have to translate it into the Theme and WooCommerce language files.
Please use the Loco translate plugin on your site. After installing the plugin please Navigate to Loco >> Themes >> XStore >> Edit the translation which you are using for the site >> Click the Sync button >> Find the words and add the translation for them and save it.
Also, please Navigate to Loco >> Plugins >> Woocommerce >> Edit the translation which you are using for the site >> Click the Sync button >> Find the words and add the translation for them and save it.
Also, please Navigate to Loco >> Plugins >> et-Core >> Edit the translation which you are using for the site >> Click the Sync button >> Find the words and add the translation for them and save it.

Note:
1. Custom (recommended)
2. This is Loco’s protected folder under “wp-content/languages/loco/” which is safe from automatic updates and provides priority over the above locations.

If this folder doesn’t exist you may need to create it and ensure it has the correct permissions.
