What is a dictionary?
A dictionary is a list of words or phrases and their definitions arranged in alphabetical order.
In an English dictionary you'll find words beginning with ‘a’ at the front and ‘z’ at the back. There are lots of words in the English language which begin with 'a', so it's not just the first letter that is important. Words are organised alphabetically according to the following letters in a word too.
For example, ‘ant’ will come after ‘ankle’. The first two letters of these words are the same, but the third letters are different. The letter ‘t’ comes after ‘k’ in the alphabet, so you find 'ankle' before 'ant' in the dictionary.
