http://testyourvocab.com/ is a more recently crafted vocabulary test than the one that was presented here a few months ago. I took it and scored 35,300. Obviously they define "vocabulary" differently than the other test. Our members rather persuasively argued that if you don't count inflections (-s, -ing, -ed, etc.), even people like Winston Churchill don't have the 100,000-word vocabulary they are often reputed to have. I scored something like 18,000 on that test. However, that test was obviously about 100 years old. It had many words that are virtually obsolete today, but none of the words from science, politics, technology and other fields that are now in common use. (E.g., "nuclear," which fits in all three categories.) This one is more modern. In many cases, even when I didn't know what a word meant, at least I could recall encountering it. I'll be interested to hear: A. What you folks think of the test, B. How you score, C. How you think they define "vocabulary", and D. What a realistic maximum score would be for a modern-day Churchill. This test may align with my Powers-Of-Three Fluency Scale, which neatly tops out at a high score of 10 for 100,000 words (approximately 3^10).
