The single most important feature of LDOCE6 is the Longman Communication 9000 (LC9000). Unlike the 3000-word defining vocabulary of earlier editions, the LC9000 is a three-tiered frequency list (3000, 6000, 9000 words) derived from a 390-million-word corpus of written and spoken American and British English.
