  This dictionary tells you about English words and how to use them in reading, writing and speaking English. It not only gives the meaning of words, it can also help you with spelling, word building, grammar and pronunciation.

To use your dictionary correctly, you will find two spellings for this word. “Colour” is used in British English, while “color” is used in American English. When there are differences between British and American spelling, the dictionary shows it with the word “BrE” for British English and “AmE” for American English.

The dictionary also helps you pronounce words correctly. If you turn to the inside back face, you will see all the phonetic letters (音标) with some words to show you how they are pronounced. Just look at the inside back cover when you’re not sure how to say a word.

    The most important reason for using a dictionary is to find out the meaning of a word--its definition.
