Lesson 3: Learning Word Families
Learn One Word, Get Four Free!
Imagine learning one new word, but getting three or four extra words for free! That is the power of learning word families. A word family is a group of words that share a common root word but have different functions (noun, verb, adjective, etc.). Learning words this way is one of the most efficient strategies to rapidly expand your vocabulary.
Key Vocabulary
-
Word Family
A group of words that share the same root word (e.g., beauty, beautiful, beautify).
-
Root Word
The most basic form of a word with no prefixes or suffixes.
Example 1: The "Success" Family
The root idea is achieving a goal.
| Word Form | Word | Example Sentence |
|---|---|---|
| Noun (the idea) | success | I wish you success in your new job. |
| Verb (the action) | succeed | If you work hard, you will succeed. |
| Adjective (describes a person) | successful | She is a successful businesswoman. |
| Adverb (describes an action) | successfully | He completed the project successfully. |
Example 2: The "Act" Family
The root idea is doing something.
| Word Form | Word | Example Sentence |
|---|---|---|
| Noun (the thing) | action | His quick action saved the day. |
| Noun (the person) | actor | He is a famous movie actor. |

| Adjective (describes a person) | active | It's important to be physically active. |
Usage Note: How to Learn Word Families
This strategy works perfectly with your vocabulary notebook and a learner's dictionary.
- Identify the Root: When you learn a new, important word (like 'decide'), recognize it as your root word.
- Use a Dictionary: Look up the root word in an online learner's dictionary. Good dictionaries will show you the "word family" or "related words" for an entry.
- Create a Family Page: In your notebook, dedicate a whole page to that word family. Write down the noun, verb, adjective, and adverb forms.
- Write Your Own Sentences: For each form, write a personal example sentence. This is the most important step to truly learn how to use each word correctly.
In Conversation
Srey explains the strategy to Bora.
Bora: Srey, I'm trying to improve my vocabulary, but it feels slow learning one word at a time.
Srey: I know what you mean. My teacher gave me a new strategy: learning word families.
Bora: How does that work?
Srey: Let's take the word 'danger', which is a noun. The adjective form is 'dangerous'.
Bora: Oh, I know that one! "A moto can be dangerous."
Srey: Right. And the verb is 'endanger', which means to put something in danger. For example, "Pollution can endanger fish in the river."
Bora: Wow. So from 'danger', I get 'dangerous' and 'endanger'.
Srey: Exactly! You learn one root idea and get multiple words. It's much more efficient.
