How does it stack up against the big names?
| Dictionary | Best For | Weakness | LDOCE 6th Top Advantage | | :--- | :--- | :--- | :--- | | Oxford Advanced Learner's | Academic writing | Less focus on spoken English | Better for listening/speaking (IPA transcription with actual recordings) | | Cambridge Advanced | Exam prep (Cambridge exams) | Smaller corpus (200M words vs Longman's 400M) | Larger database = more accurate frequency | | Merriam-Webster's Advanced | American English only | No controlled defining vocab | Longman uses 2,000-word defining vocab (easier to understand) | | Collins COBUILD | Whole-sentence definitions | Clunky software | Longman's software (DVD-ROM) is faster and more intuitive | longman dictionary of contemporary english 6th edition top
Verdict: For learners outside of the US, LDOCE 6th Top wins. For American-centric learners, it ties with Merriam-Webster's Advanced, but the Longman's "Top" app is superior.
To evaluate LDOCE6’s “top” position, a brief comparison is necessary:
| Feature | LDOCE6 | Oxford Advanced Learner’s Dict. (OALD 9th) | Cambridge Advanced Learner’s Dict. (CALD 4th) | | :--- | :--- | :--- | :--- | | Defining vocabulary | 3000 words (LC9000) | 3000 words (Oxford 3000) | 2000 words (Cambridge) | | Corpus size | 390 million words | 2 billion words (larger) | 1.2 billion words | | Frequency marking | 3-tier (9000 words) | 3-tier (Oxford 5000) | A1–C2 (CEFR labels) | | Collocation strength | Excellent (separate boxes) | Good (integrated into examples) | Moderate | | Best for | Production (writing/speaking) | Comprehension (reading/listening) | Exam preparation (IELTS, FCE) | Title: The Pinnacle of Pedagogical Lexicography: A Detailed
Conclusion of comparison: LDOCE6 is the top choice for productive use—helping learners avoid errors and use natural collocations. OALD is better for receptive use due to larger example banks.
LDOCE6 is built on the Longman Corpus Network, which includes academic, spoken, fiction, and newspaper sub-corpora.
The 6th edition is the pinnacle of the hybrid print-digital era. Inside the back cover, you receive a code for the Premium DVD-ROM (compatible with Windows and Mac). This software alone is worth the price of admission. It includes: Collocation Boxes: Each entry for a high-frequency noun
Even today, the online access (via the Pearson platform) remains active for registered users, providing a continuously updated version of the lexicon. For students who prefer digital, the mobile app version (available for purchase separately) replicates this power on a smartphone.
What truly places the Longman Dictionary of Contemporary English 6th Edition top of its class is its revolutionary frequency-based approach. Unlike standard dictionaries that treat every word equally, LDOCE 6 identifies the 9000 most critical words in the English language, divided into three tiers:
These words are marked with clear circles (●) in the text, and the accompanying DVD-ROM includes a Longman Vocabulary Trainer. This allows learners to prioritize their study time. Instead of memorizing rare words, students focus on the most impactful vocabulary first. No other dictionary offers such a data-driven, pedagogically sound approach to vocabulary acquisition.
