These dictionaries generally contain fewer entries than full-size or collegiate dictionaries, but contain additional information that would be useful to a learner of English, such as more extensive usage notes, example sentences or phrases, collocations, and both British and American pronunciations (sometimes multiple variants of the latter). In addition, definitions are usually restricted to a simpler core vocabulary than that expected of a native speaker.

Dictionaries for learners vs. dictionaries for native speakers
There are two kinds of English-English dictionaries: dictionaries for learners and dictionaries for native speakers. Dictionaries for native speakers are used by Americans, Britons, etc. to look up rare words, such as inextricable or tintinnabulation. Dictionaries for learners are used by people who are learning English as a second language.
Dictionaries for native speakers usually have more words than dictionaries for learners, but the definitions are complicated, and there are fewer example sentences. Therefore, whenever possible, you should be using dictionaries for learners. You should use “native” dictionaries only in special situations: for example, when your learner’s dictionary does not have the word you’re looking for.
