The Oxford English Dictionary (OED) is widely regarded as the accepted authority on the English language.
It is an unsurpassed guide to the meaning, history, and pronunciation of 600,000 words—past and present—from across the English-speaking world, tracing how they have changed over time. OED has its own, unique history as a living document.
