American Dictionary

The first dictionary of American English was published in April 1828. The two-volume dictionary was written solely by the American lexicographer Noah Webster. He began work on it in 1807 and finished in 1824-1825. It contained 12,000 words and 30,000-40,000 definitions that had not appeared in any earlier dictionary. The rights to the dictionary were sold in 1843 by the Webster estate to George and Charles Merriam.
