단일언어를 사용하는 국가는 어디인가?
English is the de facto national language of the United States. While there is no official language at the federal level, 32 of the 50 U.S. states and all six inhabited U.S. territories have designated English as one, or the only, official language, while courts have found that residents in the 50 states do not have a right to government services in their preferred language. Public debate in the last few decades has focused on whether Spanish should be recognized by the government, or whether all business should be done in English.
