Ethnic identity in the context of "Language shift"

Hellenization or Hellenification is the adoption of Greek culture, religion, language, and identity by non-Greeks. In the ancient period, colonization often led to the Hellenization of indigenous people. In the Hellenistic period, many of the territories which were conquered by Alexander the Great were Hellenized.

Religious identity is a specific type of identity formation. Particularly, it is the sense of group membership to a religion and the importance of this group membership as it pertains to one's self-concept. Religious identity is not necessarily the same as religiousness or religiosity. Although these three terms share a commonality, religiousness and religiosity refer to both the value of religious group membership as well as participation in religious events (e.g. going to church). Religious identity, on the other hand, refers specifically to religious group membership regardless of religious activity or participation.

Similar to other forms of identity formation, such as ethnic and cultural identity, the religious context can generally provide a perspective from which to view the world, opportunities to socialize with a spectrum of individuals from different generations, and a set of basic principles to live out. These foundations can come to shape an individual's identity.

Supraethnicity (from Latin prefix supra- / "above" and Ancient Greek word ἔθνος / "ethnos = people") is a scholarly neologism, used mainly in social sciences as a formal designation for a particular structural category that lies "above" the basic level of ethnicity. It is often paired with subethnicity, a similar technical term with the exact opposite meaning, also designating a particular structural category, but that which lies "under" the level of ethnicity. Both terms are used in ethnic studies in order to describe structural and functional relations between basic (common) form of ethnic identity and various related phenomena that are classified as belonging to "higher" (supraethnic) or "lower" (subethnic) levels. Formally, both categories (supraethnic and subethnic) are designating levels, not the contents. For example, there are several distinctive phenomena that are manifested on the supraethnic level, like: metaethnicity, multiethnicity (pluriethnicity), panethnicity, polyethnicity, or transethnicity, each of them having their own distinctive contents, but all of them sharing the same structural "supraethnic" level. There have been attempts to define some common, not only structural but also functional properties of supraethnicity, but such attempts were challenged by the present state of terminological diversity and inconsistency within the ethnic studies.
