Derived from the database of the "New Oxford Dictionary of English", the book is user friendly with different elements starting on new lines. It offers coverage of English as an international language, the defining style is straightforward and non-technical, and thousands of examples illustrate idiomatic usage.

Additional features include Wordbuilder boxes giving information on related words and thematic tables on subjects such as countries, chemical elements, and nationalities.
