English Vocabulary

How many words do you need to know in English? This is a very common question and it varies depending on your goal. Because TalkEnglish.com focuses on speaking, the vocabulary presented in this section will be the most commonly used words in speaking.

1. There are roughly 100,000 word-families in the English language.
2. A native English speaking person knows between 10,000 (uneducated) to 20,000 (educated) word families.
3. Professor Paul Nation found that a person needs to know 8,000-9,000 word families to enjoy reading a book.
4. Studying heritage language learners reveal that a person with a vocabulary size of 2,500 passive word-families and 2,000 active word-families can speak a language fluently.

Many people do not know what a heritage language learner is. Let's say a person from Mexico moves to the US at the age of 5. The person knows basic Spanish and is fluent for a 5 year old but eventually English will become dominant. This person whose first language is Spanish actually does not know many Spanish words and must study Spanish to retain it. Because they grew up for 5 years speaking Spanish, they are a different type of language learners. This type of person is considered a heritage language learner.

GOOD NEWS - If your goal is to speak English fluently, you are not required to study 10,000 words. 2,000 is enough to get you started.
