Did You Know?
The first dictionary of the English language appeared in 1604. Robert Cawdry's A Table Alphabetical contained about 3,000 words.
John Kersey the Younger is regarded as the first professional lexicographer whose introductory work, A New English Dictionary, appeared in 1702.
The Oxford English Dictionary, the largest English-language dictionary, contains some 290,000 entries with some 616,500 word forms. There are lots of slang and regional words that are not included in the OED2, and the big dictionary omits many proper names, scientific and technical terms, and jargon as a matter of editorial policy (e.g., there are some 1.4 million named species of insect alone). All told, estimates of the total vocabulary of English start at around three million words and go up from there.
