What are some subgroups of the Europeans?

Europeans can be categorized into various subgroups based on linguistic, cultural, and ethnic lines. Major subgroups include the Germanic peoples (e.g., Germans, Scandinavians, and Dutch), Romance peoples (e.g., Italians, French, and Spaniards), and Slavic peoples (e.g., Russians, Poles, and Czechs). Additionally, there are distinct groups such as the Celts (e.g., Irish and Scots) and the Basques, each with unique languages and cultural identities. Other minority groups, including the Sami in Northern Europe and various ethnic communities in Eastern Europe, further enrich the diversity of the continent.
