There are two main types of dictionaries: paper dictionaries and online dictionaries.
A paper dictionary has all the words in alphabetical order. You can find a word by turning the pages. It usually gives the spelling, pronunciation, meanings and example sentences of a word. It is a good choice when you want to learn the basic knowledge of a word. However, it may take you some time to find the word you need.
An online dictionary is becoming more and more popular. You just need to type the word in the search box, and then you can get a lot of information about it immediately.

Using a dictionary is not just about looking up the meanings of words. It can also help us in many other ways.
In reading, when we meet a difficult word like “pragmatic”, looking it up can help us understand the whole passage better. The dictionary tells us that “pragmatic” means “dealing with things sensibly and realistically”. Then we can get the main idea of the text more easily.
In writing, if we want to make our writing more colorful, we can look up synonyms. For example, if we always use “nice”, looking up a dictionary may give us some better words like “pleasant”, “delightful”.
Moreover, learning to use a dictionary can develop our self - learning ability. We can solve problems by ourselves instead of always asking teachers or classmates for help.
