How many words do we actually know? What would it take to identify and count all words known to a person? A hard nut to crack, isn't it? Possibly, we may dig into a big printed dictionary and flipping page by page, count all familiar words.
It's a feasible task, but it would be like trying to count all grains in a handful of sand. Is there a better way? Yes, there is. Let's first count out say 100 grains, weigh them and, according to their weight, figure out the number of the rest by using some math algorithms. Here at Manylex, weight means the frequency of use of a given word only conversely, i.e., the more frequent (simple) is the word, the less its weight. We've built a counter and "weighing scales" for you, so you don't have to bother with all this weight-math stuff.
Check the box for each word whose definition (at least one) you know for sure. If you really want an accurate result, be honest. Do not tick the words, that you might have seen once a long time ago, so they seem to be familiar, but you have doubts about their meaning. Don't look up words in a dictionary. And don't worry about your time, the test will take only a few minutes to complete. If your vocabulary is big enough, you will have to go through at most 152 words. Take the test and compare your score with many people from various countries.
Hint for Windows users: you can navigate through the checkboxes using the Tab key and select with the Space bar. To skip a word hit Tab once again.
