Using Glossaries to Define Words

You will learn how to use a glossary along with other text features, like bold words and headings, to find and understand new words in longer passages. This builds on basic glossary skills by showing you how clues in the text point you to the right definitions quickly.

Introduction

When you read a longer story or a science article, you will meet many new words. Some of these words are hard to figure out just by looking at them. A glossary can help, especially when you use it together with other clues in the book called text features. You will learn how to spot a tricky word, find it fast, and check that its meaning fits the sentence.

Text Features that Point to the Glossary

In longer passages, writers often give you hints about which words are important. A word might be printed in bold or in italics. Sometimes a heading or a caption near a picture uses a special word too. These are all text features, and they are clues that tell you, "This word might be in the glossary!"

Before you even open the glossary, look through the passage for these clues. Notice bold words, headings, and labels on pictures or diagrams. Each one might lead you to a definition that helps the whole page make more sense.

The bold word in the passage matches an entry in the glossary.

Finding a Word in a Longer Passage

When a passage has many pages, you may see several unfamiliar words. Try this order of steps so you do not get lost:

First, read a section and mark any word you do not know, especially bold or italic words. Second, turn to the glossary and use alphabetical order to find each word. Third, read the definition and go back to the sentence in the passage. Ask yourself if the meaning fits. If a word like "reef" or "current" has more than one meaning, the sentence around it will help you pick the right one.

For example, if a science passage says the "current pulled the boat," you might find two meanings for "current" in the glossary. One meaning is about electricity, and one is about moving water. Since the passage talks about the ocean, you would choose the meaning about moving water.

Using Glossaries with Other Text Features

A glossary works even better when you use it with other parts of the book. A caption under a picture might already explain part of a word's meaning. A heading might tell you the whole section is about ocean animals, which can help you guess a word before you even check the glossary. Using all these clues together makes you a stronger reader who can handle longer, harder passages.

Key Terms & Definitions

Glossary: A list of important words and their meanings, usually found at the back of a book.

Text Features: Parts of a book, like bold words, headings, and captions, that give you clues about meaning.

Practice Activities

Pick a longer passage from a book you are reading. Look for bold or italic words and any headings or captions near them. Use the glossary to check each word's meaning, then reread the sentence to make sure the meaning makes sense. Try this with words like "habitat," "current," or "migrate."
