Selling in multiple languages

With Shopify Markets, you can offer multiple languages on a single store. To translate your content,you can use a compatible third-party application  or import your translations directly into Shopify..All of the properties are stored in localized translation files that can be edited or managed through your theme source control. 

If you want to provide a unique customer experience, depending on the language—for example, different content or branding based on the customer’s language—without extensive theme customizations, you might find it easier to set up multiple Shopify stores, each with a different default language. You can add a store selector to your theme, typically in the form of a dropdown or pop-up, to help customers switch to the correct store for their country/region and language.
