To create a query that aggregates clicks grouped by the language of the recipient, the developer needs to use Data Views that store subscriber and click information. The required Data Views are:

_Subscribers (A) - This Data View contains information about subscribers, including their profile attributes such as language.

_Click (D) - This Data View contains information about click events for email messages, which can be used to aggregate clicks.

The query would join these Data Views on a common identifier (e.g., SubscriberKey) and group the results by the language attribute.
