What is in each layer?

The Learn These Words First dictionary is arranged in layers to eliminate circular definitions and make the dictionary accessible for beginning-level ESL students:

 

• Lessons 1 and 2 use captioned illustrations to explain essential words (NSM universal linguistic concepts). Translations are given in multiple languages.
• Lessons 3 through 12 build the vocabulary one word at a time. Each word is explained in English, using only words that have already been introduced. Lessons include example sentences and questions to help review new vocabulary.
• The alphabetical index lists the 2000 words in the Longman Defining Vocabulary. Each of these words is defined using only the 360 words from the lessons.
• Using the 2000 words from the layers above, students can read any definition in the Longman English Dictionary Online.
