The United States does not have an official language at the federal level, but the most commonly used language is English, which is the de facto national language. In addition, 32 U.S. states out of 50 and all five U.S. territories have declared English as an official language. The majority of the U.S. population (77.5%) speaks only English at home as of 2023. The remainder of the population speaks many other languages at home, most notably Spanish, according to the American Community Survey (ACS) of the U.S. Census Bureau; others include indigenous languages originally spoken by Native Americans, Alaska Natives, Native Hawaiians, and native populations in the U.S. unincorporated territories. Other languages were brought in by people from Europe, Africa, Asia, other parts of the Americas, and Oceania, including multiple dialects, creole languages, pidgin languages, and sign languages originating in what is now the United States. Interlingua, an international auxiliary language, was also created in the U.S.

With a total number of 196 sovereign states recognized internationally and an estimated number of roughly 5,000 to 7,000 languages spoken worldwide, the vast majority of languages are minority languages in every country in which they are spoken. Some minority languages are simultaneously also official languages, such as Irish in Ireland or the numerous indigenous languages of Bolivia. Likewise, some national languages are often considered minority languages, insofar as they are the national language of a stateless nation.

In addition, some signs feature synchronic digraphia, the use of multiple writing systems for a single language.
