Publication of Noah Webster’s Dictionary on April 15, 1828

On April 15, 1828, Noah Webster, an influential lexicographer, educator, and author, published his landmark work, An American Dictionary of the English Language. This monumental publication played a crucial role in standardizing American English by establishing conventions that distinguished it from British English.

Context and Background

Noah Webster was born in 1758 in Connecticut and was educated at Yale College. He became deeply invested in education and language, believing that a distinctive American culture necessitated linguistic independence from Britain. In the years following the American Revolution, there was a strong nationalistic movement aimed at forging a unique American identity. Webster’s efforts were part of this broader attempt to cultivate an American form of English that reflected the nation’s evolving identity.

Prior to publishing the dictionary, Webster had already made significant contributions to American education through the publication of his textbooks, which included The American Spelling Book in 1783, widely known as the “Blue-Backed Speller.” This book became one of the most popular textbooks of its era.

Key Features of the Dictionary

An American Dictionary of the English Language consisted of 70,000 entries, substantially more than Samuel Johnson’s 1755 British dictionary, which contained around 40,000 words. Webster’s dictionary not only expanded the number of entries but also introduced several innovations:

  • Americanized Spellings: Webster advocated for simplified and distinctive American spellings, such as “color” instead of “colour” and “honor” instead of “honour”. These changes were guided by his belief in phonetic spellings that better represented American pronunciation.

  • Definitions: Webster’s definitions were often precise and informative, reflecting his commitment to clarity and education. His work not only included the meanings of words but also their etymologies, which added a layer of historical context.

  • Incorporation of Americanisms: Webster’s dictionary included words and phrases that were unique to American English. This inclusion was pivotal in documenting the evolution of the language in the United States.

Impact and Legacy

Webster’s dictionary was initially met with mixed reviews, but its importance grew over time as it became a definitive reference for American English. The dictionary’s publication marked a significant moment in the cultural and intellectual independence of the United States from Britain. It helped solidify a sense of national identity and unity through language.

The dictionary went through several editions, eventually leading to the formation of Merriam-Webster Inc., which continues to publish updated versions to this day. Noah Webster’s work laid the foundation for a distinct American lexicon that reflects the country’s diversity and innovation.

Webster’s contributions endure as a testament to his vision of American linguistic independence and unity, establishing a legacy that continues to influence English language standards in the United States.
