An ethnolinguistic group is a group of people who share a common language and culture. It means they speak the same language and also have similar customs and ways of living. For example, if there are people who live in the same area, speak the same language, and share the same festivals, traditions, and beliefs, they can be considered an ethnolinguistic group.
Think of it like this; just like we have different colors of crayons. Some crayons are blue, and some are red, some are green, etc. Similarly, people also have different languages and cultures that make them unique. People who speak the same language and share similar beliefs, customs, and traditions have many things in common, so they can be grouped together based on these similarities.
Some examples of ethnolinguistic groups include the Basque people who mostly live in parts of Spain and France, the Maori people of New Zealand, and the Amish people of the United States. These groups have their own unique language, traditions, and practices that make them different from other groups.
So, to sum it up, ethnolinguistic groups are groups of people who share a common language, culture, history, and traditions. It's like a special club where members have a lot in common and can communicate with each other easily in the same language.
