The entries in the Oxford Advanced American Dictionary are chosen on the basis of their frequency and usefulness for learners of English.
Dictionary editors consult a corpus (= a database of real English, spoken and written) to analyze the usage of words. Based on this information, and based on their experience as English teachers, the editors decide which words are important enough to be included in the dictionary.
The size of the English language means that, unfortunately, OAAD cannot include every word in existence. Some words are excluded because they are rare or highly specialized.
If you are interested in rare or more specialized words, we recommend that you also consult a dictionary that is not designed specifically for learners of English. For example, the New Oxford American Dictionary. You can find information about other non-learners' dictionaries from at www.oxforddictionaries.com.
You can hear how words are pronounced in American English by clicking on the speaker icon within the entries. You can use these as a reliable model to practice your own pronunciation. Pronunciation is also shown in the dictionary using phonetic symbols. If you need help reading these symbols, look at this Pronunciation Guide.
You need to have the latest version of Adobe's Flash Player installed on your computer to hear the sounds. Go to Adobe's website to download the latest version of Flash Player, and follow the instructions there for installing it. When you have installed it, you will need to close and re-open your web browser. Once this has been done, you will be able to hear the pronunciation sounds.
Symbols and labels used in the dictionary are explained in this Guide to Labels.
The social bookmarks provide a way for you to share an entry with your online community or to bookmark it for you to easily find again later.
This website contains lists of the Oxford 3000™ words, Academic Word List words, entries with a picture, and entries with a usage note.

The Oxford Advanced American Dictionary is full of information that can help you to become a better writer in English.
The dictionary entries not only tell you what words mean, they also tell you how words are used. If you want to use a word correctly, look carefully at the grammar information, the example sentences, and the labels which tell you whether a word is formal, informal, or technical.
The dictionary also contains hundreds of usage notes that will help you build your vocabulary and improve your accuracy. There are several different types of note, including Thesaurus, Topic Collocations, Language Bank, Vocabulary Building, Which word?, Grammar, More About, and AWL Collocations.
For even more help with writing, including a wide variety of model texts, look at the Oxford Writing Tutor in the book version of the dictionary, and the Oxford iWriter on the CD-ROM (which is included when you buy the print dictionary).
