A guide to guessing French vocabulary using word families

Discover the Power of Word Families – A Smart Way to Remember French Vocabulary


In this Rendez-vous Tuto, Ellie dives into a smart, intuitive way to build vocabulary that many learners overlook: word families.

Unlike grammar, vocabulary often feels scattered and hard to pin down. But what if you could unlock a whole set of related words just by recognizing one root? That’s the idea behind word families—a technique that not only makes new words easier to remember but also helps you guess unfamiliar ones in context.

Drawing from immersive experiences in France and insights from language acquisition research, Ellie introduces a method that’s both structured and adaptable. Whether you're brushing up your skills or starting from scratch, this approach offers a gentle yet powerful boost to your French.

What Are Word Families, Exactly?

Word families are groups of words that share a common root. From a single verb like inviter, you can derive nouns (invitation), adjectives (invitant), and even more complex forms (réinviter). These families often carry the same core meaning, so once you grasp the root, you're halfway to understanding several related words.

🧩 Example:

  • Root: invit

  • Word family: inviter, invitation, réinviter, invitant

It’s a bit like discovering a secret code that lets you read more fluently and express yourself more freely—without constantly reaching for a dictionary.


Why This Approach Works

Ellie explains how using word families taps into your brain’s natural pattern recognition, making vocabulary more “sticky.” Here’s why it works:

  • Faster Learning: You learn 4–5 words for the effort of 1.

  • Improved Memory: Familiar patterns help words stick long-term.

  • Better Reading Skills: You’ll start to recognize and decode new words more easily.

  • More Confident Speaking: You’ll have more vocabulary ready when you need it.


Tips from the Tuto: How to Practise with Word Families

Ellie shares a few techniques you can try today:

🌱 1. Create Mini Mind Maps

Start with a root word like porter and build outwards:
importer, reporter, déporter, portatif, portage

🎯 2. Guess New Words in Context

Notice prefixes (re-, dé-, im-) and suffixes (-tion, -able, -ant) to make educated guesses about unfamiliar terms.

🗣️ 3. Say It Out Loud and Add Meaning

Try saying new words aloud while imagining them in context. For example, when you say invitation, imagine a party invite in your hand—something tangible and emotional.


A Quick Grammar Reminder

Understanding how words function in sentences will help you make the most of this technique. If you're not quite sure about parts of speech like verbs, nouns, adjectives, and adverbs, we recommend revisiting the Parts of Speech Tutos in the Vocabulary Library.
