Webster's Dictionary

'''''Webster's Dictionary''''' is any of the US English language dictionaries edited in the early 19th century by Noah Webster (1758–1843), a US lexicographer, as well as numerous related or unrelated dictionaries that have adopted the Webster's name in his honor. "''Webster's''" has since become a genericized trademark in the United States for US English dictionaries, and is widely used in dictionary titles.

Merriam-Webster is the corporate heir to Noah Webster's original works, which are in the public domain. Provided by Wikipedia
