The Macmillan School Dictionary is completely relevant to the needs of young people who are studying their subjects through the medium of English and preparing for school exams. It explains – clearly and accurately – the vocabulary needed for successful study in any of the key school subjects. At every stage, experienced teachers, textbook writers, and syllabus designers have contributed their expertise, giving us a clear idea of what you really need to know at this level. In addition, we have used state-of-the-art software to analyse the corpora, so that we have a scientific basis for selecting the words to include and for deciding how much information is needed about each word.
