“Store Views” is the most appropriate feature for displaying your store in multiple languages. To create a new “Store View”, click “Create Store View” in the upper right corner. Select the store, this “Store View” will be associated with. The “Code” and “Sort” order fields have the same functionality as for websites. For a “Store View” to be visible on the front-end, it must be “Enabled”. You can remove it from the front-end without deleting it by selecting “Disabled” option.

You can set unique locales for each “Store View”. Simply navigate to System > Configuration, and select the “General” tab from the left column. In the “Current Configuration Scope” drop-down above, select the desired “Store View”. Uncheck the “Use website” checkbox next the locale settings, and select the locale you prefer. This locale will only apply to this “Store View”.
