The Longman Communication 3000 is a list of the 3000 most frequent words in both spoken and written English, based on statistical analysis of the 390 million words contained in the Longman Corpus Network – a group of corpuses or databases of authentic English language.
The Longman Communication 3000 represents the core of the English language and shows students of English which words are the most important for them to learn and study in order to communicate effectively in both speech and writing.
To ensure that users have access to the appropriate information, the Longman Dictionary of Contemporary English marks all the words that are in the Longman Communication 3000 in red accompanied by special symbols: W1 , W2 , and W3 for words that are in the top 1000, 2000 and 3000 most frequent words in written English, and S1 , S2 and S3 for the top 1000, 2000 and 3000 most frequent words in spoken English.
Nowadays, many learner’s dictionaries include information about the most frequent words in English, but Longman dictionaries are the only ones to highlight the differences between spoken and written frequency.
