π The Story of Dictionaries
Have you ever read a word you did not know? Maybe it was in a book, on a sign, or on a screen. Long ago, people had this same problem! So smart people made special books to help. These books are called dictionaries. Let's learn how they were made!
So for hundreds of years, people have been making tools to help us learn new words. Today, you get to use these tools too. A glossary is a mini dictionary in the back of a book. A dictionary is a whole book (or website) full of words and their meanings. Let's learn how to use both!
π Big Ideas to Know
Before we start looking up words, let's learn four important things. These are the big ideas that will help you use glossaries and dictionaries like a reading superstar!
ABC Order Is the Key
A Glossary Lives in a Book
A Dictionary Has LOTS of Words
Print and Digital
π¨ See How They Look
Let's look at a picture that shows what a glossary page and a dictionary page look like. This will help you know what to look for when you open one!
Look at the picture above. On the left is a glossary. See how it has words from a book about animals? It even tells you the page number where the word is used! On the right is a dictionary. It has guide words at the top to help you know which words are on that page. It also shows you how to say each word. Pretty cool, right?
π How to Look Up a Word
Now let's learn the steps to find a word! Whether you are using a print glossary, a print dictionary, or a digital dictionary, these steps will help you.
Steps for a Print Glossary
- Step 1: Go to the back of your book. That is where the glossary lives.
- Step 2: Think about the first letter of the word you need. If the word is "migrate," the first letter is M.
- Step 3: Look for the M section. Remember, glossaries are in ABC order!
- Step 4: Read the meaning next to the word. Now you know what it means!
Steps for a Print Dictionary
- Step 1: Think about the first letter of your word. Open the dictionary to that letter section.
- Step 2: Look at the guide words at the top of each page. Guide words show you the first and last word on that page.
- Step 3: If your word comes between those two guide words in ABC order, your word is on that page!
- Step 4: Read the meaning. Some words have more than one meaning. Pick the one that makes sense in your sentence.
Steps for a Digital Dictionary
- Step 1: Open the dictionary on your computer or tablet. (Your teacher might show you which one to use.)
- Step 2: Find the search box. Type your word in the box.
- Step 3: Press Enter or tap the search button.
- Step 4: Read the meaning that pops up! Some digital dictionaries even let you hear the word said out loud. π
π What You Can Find
Glossaries and dictionaries tell you different things about a word. Let's see what information each one gives you!
As you can see, a dictionary gives you more information than a glossary. It can tell you how to say a word, what kind of word it is (like a noun or a verb), and even give you a sentence with the word in it. A glossary is simpler β it gives you the meaning and sometimes the page where you can find the word in the book. Both are very helpful!
Knowing where a letter is in the alphabet helps you find words faster. If a word starts with B, you know it is near the beginning. If it starts with T, you look near the end!
βοΈ Let's Try It Together!
Imagine you are reading a book about weather. You see this sentence: "The meteorologist said it will rain tomorrow." You don't know what meteorologist means. Let's find out!
βοΈ Glossary vs. Dictionary β Which Do I Use?
Both glossaries and dictionaries help you learn words. But they are a little different. Let's compare them!
| Question | π Glossary | π Dictionary |
|---|---|---|
| Where is it? | Back of a book | Its own book or website |
| How many words? | Only a few (from that book) | Thousands and thousands! |
| In ABC order? | Yes! β | Yes! β |
| Does it show meaning? | Yes! β | Yes! β (sometimes more than one) |
| Does it show how to say a word? | Usually not β | Yes! β |
| Does it have guide words? | Sometimes | Yes! β |
| Can it be digital? | Yes (in e-books) | Yes! Many websites |
| When should I use it? | When reading a book that has one | Anytime you need to look up a word |
π What Comes Next?
You are learning to use glossaries and beginning dictionaries right now. That is awesome! As you grow up, you will learn even more cool word tools.
| What You Know Now | What You'll Learn Later |
|---|---|
| Looking up a word's meaning | Finding the right meaning when a word has many meanings |
| Using ABC order to find words | Using guide words to find words super fast |
| Using a glossary in a book | Using a thesaurus to find words that mean the same thing |
| Typing a word in a digital dictionary | Using online dictionaries to learn word history and word families |
Every time you look up a word, you are building your vocabulary (that means all the words you know!). The more words you know, the better you can read, write, and talk about ideas. Keep looking up words β you are becoming a word detective! π

π Let's Remember What We Learned!
Today you learned that a glossary is a small list of words and meanings at the back of a book, and a dictionary is a big book (or website) with thousands of words. Both glossaries and dictionaries use ABC order to help you find words fast. You can use print versions (real books you hold) or digital versions (on a computer or tablet). Dictionaries also show you how to say a word and sometimes give you an example sentence.
When you see a word you don't know, you now have a plan! Check the glossary first (if your book has one). If that doesn't work, grab a dictionary or use a digital one. Read the meaning, then go back and re-read the sentence. You are a word detective who can figure out any new word! ππ
