English is a mix of several languages including French, Italian, Greek and Latin, Vietnamese and so on. This makes the number of words linguists estimate the English language to have extremely large…approximately one million words. About 170,000 of these words are in current use. The average adult English speaker has a vocabulary between 20,000 to 35,000 words. Ninety-five percent of everyday writing and speech in newspapers, most books, movies, etc. use only about 3,000 words. So…how do we prepare our students for college entrance exams when everyday life exposes them to such a narrow list of vocabulary words? —- We teach students prefixes, suffixes, and Greek and Latin roots.
