Here is how the number of words in the Oxford Dictionary—171,476 in current use—compares to the number of words in those five other languages. The figures here are taken from the Lingholic website, which base their numbers on the largest dictionary for each language. Webster's Third New International Dictionary, Unabridged, together with its 1993 Addenda Section, includes some
470,000 entries. But, the number of words in the Oxford and Webster Dictionaries are not the same as the number of words in English.
- Spanish has about 100,000 words in the Diccionario de la Real Academia Española.
- German has about 135,000 words in the Der Duden dictionary.
- 200,000 Russian words exist in the Explanatory Dictionary of the Living Great Russian.
- Italian has 270,000 in the Grande dizionario Italiano dell’uso.
- French has 100,000 words but 350,000 definitions in the Le Grand Robert de la langue Française.
It’s impossible to determine how many words there are in the English language from the dictionary alone. First, it takes a while for dictionary publishers like Oxford University and Merriam-Webster to include new words in their dictionaries. Slang and jargon also exist. There are different slang terms. Some exist depending on where you live, and others are common in many places. One example of a common slang term is “frenemy,” a
portmanteau of “friend” and “enemy.”
Jargon, words used by people in a specific profession, also add to the volume of words used in the English language. For example, medical doctors will use their profession's own terms when discussing patients. Computer programmers and IT specialists use computer jargon in their everyday work.
But,
how many words does the average person know? Robert Charles Lee, a published writer, answers this question on
Quora. He writes that “3,000 words will cover 95% of everyday writing — common texts and speech like newspapers, blogs, most books, movies, etc.” Out of those 3000 words, only “the first 1,000 words are used in 89% of everyday writing.” R.L.G at
The Economist states that based on test results at TestYourVocab.com, “most adult native test-takers range from 20,000–35,000 words.”
