With innovations such as DefinitionsPLUS and vocabulary builders, the Collins COBUILD School Dictionary of American English transforms the learner's dictionary from an occasional reference into the ultimate resource and must-have dictionary for language learners. The definitions have been created using a controlled vocabulary, and each definition has been reviewed by a team of classroom teachers to ensure that they are appropriate for learners at the intermediate level.
* Each definition is written using the high-frequency words and naturally occurring grammatical patterns native speakers actually use, making every entry a model of how to use the language appropriately. * "Word Webs" present related vocabulary within a context. * "Picture Dictionary" boxes illustrate vocabulary and concepts. * "Word Partnerships" show high-frequency word patterns. * "Thesaurus" boxes offer both synonyms and antonym for the target word. * "Word Link" boxes "Word Links" highlight the most common prefixes, suffixes, and word roots of the target word. * "Usage" sections clarify the use of commonly misused words and other confusing language, and explain cultural references.
