How many words do native speakers know?

At present the best conservative rule of thumb that we have is that up to a vocabulary size of around 20,000 word families, we should

expect that native speakers will add roughly 1000 word families a year to their vocabulary size. That means that a five year old

beginning school will have a vocabulary of around 4000 to 5000 word families. A university graduate will have a vocabulary of around

20,000 word families (Goulden, Nation and Read, 1990).
