Your shop's default cart language is set to 'Basket' when you set up an account with the platform.
You are able to change this by going to Settings > Formats > 'Shopfront Basket/Cart Language'.
You can choose between 'Basket', 'Cart' or 'Shopping Bag'. Hit save and you will see your chosen word on your shop's homepage and product page.
