That’s hard to say. The number of words listed in the various dictionaries vary; The Oxford English Dictionary, 2nd edition (OED2) includes over 600,000 definitions, Webster's Third New International Dictionary, Unabridged estimates the number to be much higher, and others sources claim the English language has recently crossed the 1,000,000-word threshold. It’s hard to say, however it is estimated that about 25,000 words are added to the language each year.
