The display method has been upgraded to more faithfully represent each part of speech using the CEFR-J (Japanese version) word list.

■ Dictionary Content Guide ■
- Sufficient number of entries required for high school basic level: 51,000 English-Japanese entries / 24,000 Japanese-English entries.
- Includes a compact Japanese-English mini-dictionary. Also includes a mini-dictionary for high school vocational courses and ICT terminology.
- Includes approximately 24,000 audio recordings.
- A dictionary for junior high and early high school students, easy to use even for readers who struggle with English, and ideal for adults relearning.
- The focus pages provide detailed explanations of the "most important basic words." By summarizing the essence revealed through big data analysis, you can efficiently acquire the basics of English and improve your communication skills (speaking and writing).
- The column "Let's Learn with Chunks!" encourages you to speak English fluently by learning representative chunks (groups of several words with meaningful units) of basic verbs in Japanese → English order.
- Basic and important words are carefully explained with dedicated space in the main text. Furthermore, the book provides powerful support for learners with over 1000 columns that clearly explain the meaning and usage of words, including "Meaning Maps" that compactly organize polysemous words, "Collocations" that collect words that are often used together, and "Related Words" that organize synonyms.

* Basic verbs are accompanied by a column called "Let's Learn with Chunks!" which includes chunks (groups of several words with meaningful units), and important words are placed with "CAN-DO Tips" columns that show "what you will be able to do in English" once you master a certain expression, ensuring that vocabulary learning does not end with mere memorization of facts.

* The CEFR is an indicator of language proficiency levels that has influence not only in Europe but all over the world, and is deeply related to the content of the foreign language subject in Japan's current curriculum guidelines. In accordance with the CEFR-J word list developed to apply this to English education in Japan, "Ace Crown 4th Edition" displays the A1 to B2 level for important words by part of speech. You can see whether the words you look up are important words that should be studied in depth or not, allowing you to proceed with learning efficiently. * Focusing on important words at A1 and A2 levels, the newly developed CEFR level for each word meaning is also displayed. Important words tend to have many meanings, but this clearly shows learners which meanings are particularly important and must be memorized.

* Two new appendices have been added: a "Manual for Creating English Sentences for Output" and a "CAN-DO Guide to Useful Vocabulary and Expressions" for communicating in English.
