Here's why:
* Historical reasons: A significant portion of the US population has roots in Spanish-speaking countries, particularly from Mexico, Central America, and South America.
* Immigration: Ongoing immigration from Spanish-speaking countries continues to contribute to the growth of the Spanish-speaking population.
* Cultural influence: Spanish language and culture are increasingly integrated into American society, influencing music, food, and entertainment.
While English remains the official language of the United States, Spanish is widely spoken and understood in many parts of the country, especially in areas with large Hispanic populations.
