Using this dictionary

      A dictionary helps you to find out what a word means and how to spell it correctly. The words in a dictionary are arranged in alphabetical order.

      How to find a word

      • You can use the Index at the back of the ebook which lists all of the dictionary words in alphabetical order. Scroll through the Index until you find the letter your word begins with, then look down the words until you find the one you are looking for. You can then follow the link to the entry in the dictionary.

      • You can use the Contents page at the front of the book, which has a link to every letter in the dictionary. Follow the link to the letter your word begins with, then look through the entries in this letter until you find the word you are looking for.
