OED
From Conservapedia
The Oxford English Dictionary (OED) is a renowned, but liberal-leaning, dictionary begun in 1857 which provides current and historical meanings of virtually every word in the English language.
From the OED website: "you’ll also find the history of individual words, sometimes from as far back as the 11th century, and of the language—traced through 3.5 million quotations, from classic literature and specialist periodicals to film scripts, song lyrics, and social media posts."[1]
