Final answer:
Ethnicity refers to a trait of large groups sharing customs, language, religion, or origin, contributing to a shared identity within the larger society.
Step-by-step explanation:
The trait of large groups who share the same customs, language, religion, origin, and so on, is typically referred to as ethnicity. Ethnicity encompasses common characteristics of culture, religion, or language shared by a group, shaping a collective identity within a larger society. This shared identity is deeply consequential as it forms a profound and common identity among individuals who possess these traits. Ethnicity often influences group alignments and impacts social interactions, political representation, and maintains cultural traditions.
Throughout history, as nations evolved, many have been founded on such things as a shared language, ethnicity, religion, or sense of common origin. Even within modern states, ethnicity can create a sense of belonging for groups, and it can also lead to political or social movements by groups who feel marginalized or wish for greater recognition or autonomy. Examples include national identity groups that object to the political or territorial status quo, often seeking more representation or protection of their unique cultural practices.
