Who authored "A Dictionary of the English Language"?

The correct answer is Samuel Johnson, who is credited with compiling "A Dictionary of the English Language," first published in 1755. This monumental work was one of the first comprehensive dictionaries of the English language and played a significant role in standardizing English spelling and grammar during a time when the language was still evolving.

Johnson's dictionary was notable for its use of literary quotations to illustrate word meanings, thus providing context and a rich understanding of the language. The work was also significant because it included not just definitions, but also etymologies and various meanings of words—traits that were innovative for its time.

While John Locke, Daniel Defoe, and Thomas Gray were influential figures in English literature and philosophy, they are not associated with this particular dictionary. Locke is known for his philosophical writings, especially regarding government and human understanding. Defoe is celebrated for his novels, such as "Robinson Crusoe," and Gray is recognized for his poetry, including "Elegy Written in a Country Churchyard." However, none of them contributed to the creation of a comprehensive dictionary like the one authored by Johnson.
