This edition includes thousands of new words and meanings covering both specialist and technical areas and the general language of today. Entries for people and places, which have always been a feature of the Collins English Dictionary, have now been included in this concise edition so that the dictionary has over 15,000 encyclopaedic entries. Special attention is given to spelling and usage with a supplement on English in usage that centres on points in modern language use, ranging from confusable words to broader topics like letter writing and sexism in language.
