Lesson 14

Adjective Agreement and Placement

Recommended resources

Bonjour!

In our last lesson, you learned how to introduce yourself, and we touched on a key concept in French grammar: adjective agreement. You saw that to say you are American, the word changes depending on your gender: un homme américain, but une femme américaine.

Today, we're going to dive deep into that concept. This lesson is all about making your descriptions richer and more accurate by mastering French adjectives. We'll cover the two fundamental rules you need to know: how to make adjectives agree with the noun's gender and number, and where to place them in a sentence. This skill will allow you to describe people, places, and things with precision—a vital step toward fluency.

1. The First Rule: Agreement (L'Accord)

In English, adjectives are simple: we say "a green car" and "green cars." The adjective "green" never changes. French is different. The adjective must always match, or "agree with," the noun it describes in both gender (masculine/feminine) and number (singular/plural).

This means one adjective can have up to four forms. For example, vert (green):

  • Masculine singular: un livre vert (a green book)
  • Feminine singular: une voiture verte (a green car)
  • Masculine plural: des livres verts (green books)
  • Feminine plural: des voitures vertes (green cars)

General Rules for Agreement

Let's start with the basics of how to form these different versions.

Gender and number agreement of adjectives in French

The BBC Bitesize article on adjective agreement provides a clear and structured overview of the main rules. We'll start with the most common patterns.

Please read the sections 'Key points about gender and number agreement in French' and 'Agreeing by adding 'e', 's' or 'es''. Focus on the table showing the four forms of 'différent'.

As you just read, the standard rule is:

  • Add -e to the masculine singular form to make it feminine.
  • Add -s to make it plural.
  • Add -es for the feminine plural.

Of course, French has exceptions and specific patterns depending on the adjective's ending. Let's look at the most frequent ones. This chart is a great visual summary of the rules we'll cover.

French Adjective Agreement and Placement Anchor Charts
This chart summarizes the key rules for both adjective agreement and placement. Refer to it as we go through the different patterns.

Common Spelling Changes

Many adjectives change their spelling in the feminine form. Here are some of the most common patterns to recognize:

  • Masculine ending in -eux → Feminine becomes -euse
    • un garçon sérieux (a serious boy)
    • une fille sérieuse (a serious girl)
  • Masculine ending in -f → Feminine becomes -ve
    • un homme actif (an active man)
    • une femme active (an active woman)
  • Masculine ending in -er → Feminine becomes -ère
    • le premier (the first)
    • la première (the first)
  • Adjectives ending in -n or -l often double the consonant before adding -e:
    • un bon vin (a good wine) → une bonne pizza (a good pizza)
    • personnel → personnelle (personal)
Test your understanding!

Make the adjective (créatif) agree with the noun in the following sentence:
"Elle a des idées très _______." (She has very creative ideas.)

Show answer

"Elle a des idées très créatives."

Here's why:

  1. Idées is a feminine noun (une idée).
  2. It's plural (des idées).
  3. The adjective créatif ends in -f. The feminine form is créative.
  4. For the feminine plural, we add an -s: créatives.

2. The Second Rule: Placement (La Place)

Now that you know how to make adjectives agree, where do you put them?

The general rule is simple: most French adjectives go after the noun. This is a major difference from English.

  • un chat noir (a black cat)
  • une histoire intéressante (an interesting story)
  • un problème difficile (a difficult problem)

The "BAGS" Exception

However, a small group of very common adjectives come before the noun. A helpful mnemonic to remember them is BAGS:

  • Beauty: beau (beautiful, handsome), joli (pretty)
  • Age: jeune (young), vieux (old), nouveau (new)
  • Goodness: bon (good), mauvais (bad)
  • Size: grand (big, tall), petit (small), gros (fat, big)

Let's watch a short video that explains this rule very clearly.

French adjectives: BEFORE or AFTER the noun?

The video 'French adjectives: BEFORE or AFTER the noun?' from Learn French With Alexa is excellent for understanding the BAGS rule.

Watch from the beginning to 05:38. Pay close attention to the examples given for each category of the BAGS acronym.

So, you would say:

  • un petit chat (a small cat) -> Size
  • une jeune femme (a young woman) -> Age
  • un bon repas (a good meal) -> Goodness
  • une belle maison (a beautiful house) -> Beauty

3. Important Irregular Adjectives: Beau, Nouveau, Vieux

Three of the most common BAGS adjectives—beau, nouveau, and vieux—are a bit tricky. They have an extra masculine singular form that is used when the noun that follows begins with a vowel or a silent 'h'. This change is purely for pronunciation, to make the phrase flow more smoothly.

  • beau → bel
  • nouveau → nouvel
  • vieux → vieil

Let's see this in action:

  • un beau garçon (a handsome boy) BUT un bel homme (a handsome man)
  • un nouveau livre (a new book) BUT un nouvel an (a new year)
  • un vieux pont (an old bridge) BUT un vieil ordinateur (an old computer)

This special form is ONLY used for masculine singular nouns starting with a vowel sound. The feminine and plural forms are regular.

This next video explains these specific irregular forms perfectly.

Let's watch a segment from 'The perfect French with Dylane' that focuses specifically on these three important irregular adjectives.

Watch the video from 10:48 to 14:34. The presenter clearly explains the different forms of 'vieux', 'nouveau', and 'beau' with examples.

Test your understanding!

Choose the correct form of the adjective (vieux) for the following sentence:
"J'ai un _____ ami qui habite à Paris." (I have an old friend who lives in Paris.)

  1. vieux
  2. vieil
  3. vieille
Show answer

The correct answer is #2: vieil.

Here's why:

  1. Ami (friend) is a masculine singular noun.
  2. It begins with a vowel ('a').
  3. Therefore, we must use the special form vieil to avoid the awkward pronunciation of "vieux ami".

Conclusion

Great job today! Mastering adjectives is a huge step in making your French sound more natural and descriptive. You now have the essential tools to describe the world around you correctly.

Key Takeaways:

  • Agreement is mandatory: French adjectives must always match the gender and number of the noun they describe. The standard pattern is to add -e for feminine and -s for plural.
  • Placement has two main rules: Most adjectives go after the noun. The main exceptions, remembered by the BAGS acronym (Beauty, Age, Goodness, Size), go before the noun.
  • Watch out for irregulars: The adjectives beau, nouveau, and vieux have special masculine forms (bel, nouvel, vieil) used before a noun starting with a vowel sound.

Next Lesson: We've focused on descriptive adjectives today. In our next lesson, we'll explore two other important types of adjectives: possessive adjectives (mon, ton, son - my, your, his/her) and demonstrative adjectives (ce, cette, ces - this, that, these/those), which help specify which noun you're talking about.

À la prochaine! (Until next time!)
