American English has become the most influential form of English worldwide since the late 20th century, serving as the dominant language in government, education, and commerce across the United States. Spanning all 50 states and various territories, this unique set of varieties encompasses distinct patterns of pronunciation, vocabulary, and grammar that set it apart from other global English forms.
The roots of this linguistic evolution trace back to the British colonization of the Americas during the 17th century. As waves of settlers from different parts of the British Isles arrived, a process of dialect leveling occurred across the Thirteen Colonies, making colonial speech far more homogeneous than the diverse regional dialects found back in Britain.
