Translating your checkout
You can activate multiple languages from your Shopify admin so that customers all over the world can view content in their native language.
Add a new checkout language
For themes that are compatible with selling in multiple languages, you can change the default language of your online store, and add other languages so that customers can select their preferred language. If the language that you want isn't available, or if you want to edit the default translations, then you can create the translations yourself.
Changing the wording in your checkout
You can customize your online store by changing the default text in your checkout from your Shopify admin. You can edit the text for each field on your checkout page. This helps you personalize your checkout experience to fit your brand. For example, you can change the default error message of can't be left blank to a message that better reflects your brand.
