The English language has approximately 170,000 words, but how many of them do you actually know? Recent online quizzes have been making the rounds, testing people's receptive vocabulary. These quizzes aim to measure the number of words you can recognize in reading and listening, which is usually larger than your productive vocabulary. The results can be surprising, with some common words being ranked alongside more obscure ones.

## What happened Several online quizzes have been developed to test English vocabulary, including VocabOwl and BRAVE. These quizzes use advanced statistics and computerized adaptive testing to provide accurate results. The tests report results in word families, which means that different forms of the same word are counted as one. For example, 'limit' and 'limitless' are part of the same word family. The quizzes have been taken by over 220,000 people, providing a large dataset for comparison. ## Why it matters The results of these quizzes can be useful for language learners and teachers. By identifying areas where vocabulary is lacking, learners can focus their studies on the most important words. The quizzes can also help to identify biases in language teaching, such as a focus on reading over listening. Additionally, the quizzes can provide a fun and engaging way to learn new words and improve language skills.
