The most commonly spoken language in the United States is English. With about 80% of the population speaking it as their first language, English serves as the primary means of communication across various aspects of society, from government and education to media and business. The U.S. is a culturally diverse nation, home to speakers of many languages; however, English's dominance stems largely from historical factors, including colonization and immigration patterns. Variants of American English exist, influenced by regional accents and dialects, making the language both rich and multifaceted in its expression and usage across the country.
