Dictionaries are organized alphabetically. Guide words at the top of each page indicate the first and last entry on that page, helping users quickly locate a word. Definitions include the word's pronunciation, part of speech, meaning, and sometimes an example sentence. Understanding guide words and definition components makes dictionaries easier to use.

How is a Dictionary
Organized?

2. Dictionaries are books
that list all the words in a
language.

3. To make dictionaries
easier to use, the words
are organized in
alphabetical order. So to
use a dictionary easily,
you must know how to
alphabetize words.

4. Since there are so many
words in a dictionary,
guide words are used to
help you locate a word
quickly.
What are guide words?

5. Guide words are found at
the top of each page. They
tell you the first and last
word that is found on that
page.

6. How do guide words help
you find a word quickly?
Instead of looking at each word
on a page, which could take
forever, you just look at the
guide words and then use what
you know about alphabetizing
words to decide if your word
would be found on that page.

7. Let’s see what that means-
Let’s pretend we are
looking up the word,
science. First we would
turn to the S section.

8. Then we would use the
guide words and what we
know about alphabetizing
words to decide the
correct page in the S
section.

9. We would look at the
guide words at the top of
each page and decide
between which ones our
word would come in
alphabetical order.

10. Let’s do that for the
word science-
Which one of these pages
would contain the word
science?

11. science
The page with the guide words-
stamp - summer
Or the page with the guide words-
sandwich - seventy
