What does the vocabulary consist of
- noun (Proper and common, countable, uncountable, collective, concrete, abstract nouns...)
How many words do you need to speak?
The researches about vocabulary size shows that typically native speakers use more than 15,000 words
You can communicate with 3,000-6,000 words easily
If you have 6,000-9,000 words, you can get novels, news, broadcasts and speak fluently
The Oxford English Dictionary has over 600,000 words and nearly 170,000 actively used words. However, there is no study estimating english vocabulary size more than 50,000.
