4000 Essential English Words
The 600 words in each book of this series along with the additional target words presented in the appendices included in the first three books of the series are the most valuable words in English. They were found by analysis of a collection of English course books from various levels in the primary, secondary, and tertiary school systems. The words included in this series were chosen because they occurred in different levels of these materials frequently. Because of the way that they were chosen, these words have the following characteristics:
- They are useful in both spoken and written English. No matter what English course you are studying, the words in these books will be of value to you.
- Each word in these books is a high-frequency word. This means that the effort in learning the words is well repaid by the number of times learners have a chance to encounter or use them.
- These books as a whole cover a large proportion of the words in any spoken or written text. They cover at least 80% of the words in newspapers and academic texts, and at least 90% of the words in novels. They also cover at least 90% of the words in conversation.
