French Adjective Agreement
French adjectives have four forms - masculine singular, feminine singular, masculine plural, feminine plural - and they agree with the noun on both axes.
The four-form pattern
| Masc sg | Fem sg | Masc pl | Fem pl |
|---|---|---|---|
| grand | |||
Build the feminine from the masculine, then add -s for the plural of either. Adjectives ending in -s or -x already don't change in the masculine plural (français -> français).
The feminine endings
The default is add -e. Then there are six predictable shortcuts:
| Masculine ending | Feminine ending | Example |
|---|---|---|
| default | + e | -> |
| -e (already) | no change | -> |
| -x | - | -> |
| -el | - | -> |
| - | -nne | -> |
| -on | -nne | -> |
| -f | -ve | -> active |
| -er | -ère | -> |
These shortcuts cover most adjectives you'll meet. A small irregular set has to be learned per word: / , / , / , / , sec / , / , / , long / , / , / .
The plural
- Default: add -s (petite -> petites, grand -> grands).
- Already ends in -s or -x: no change in the masculine plural (français -> français, heureux -> heureux). Feminine plural still adds -s (françaises, heureuses).
- Ends in -al: masculine plural becomes - (national -> nationaux, principal -> principaux). Feminine plural is regular (nationales).
- Ends in -: masculine plural adds -x (beau -> beaux, nouveau -> nouveaux). Feminine plural still adds -s (belles, nouvelles).
Position: after the noun by default
Most French adjectives go after the noun.
- (a red car)
- (an interesting book)
- (an intelligent girl)
- (a French man)
The BAGS set: before the noun
A small closed group sits before the noun. The mnemonic BAGS covers them:
- Beauty: beau, joli
- Age: jeune, vieux, nouveau
- Goodness: bon, mauvais
- Size: grand, petit, gros, long, haut
Examples:
- (a beautiful car)
- (a new book)
- (a good friend)
- (a small problem)
When two BAGS adjectives stack, the order is flexible: or are both heard, with a slight preference for size + beauty.
The vowel-buffered masculine forms
Three BAGS adjectives have a third masculine singular form used before a vowel or silent h:
| Masc sg | Before vowel | Fem sg | Masc pl | Fem pl |
|---|---|---|---|---|
- but
- but
- but
Same pattern as vs - bridge the vowels.
Worked examples
- chat . (The small black cat is sleeping.)
- ensoleillée. (A lovely sunny day.)
- à Lyon. (My French friends live in Lyon.)
- C' . (It's an old story.)
- restaurants. (Those are good restaurants.)
- . (She's wearing a white dress and black shoes.)
Common mistakes English speakers make
Forgetting to agree the adjective in writing: intelligent instead of . The plural -s is silent in speech but mandatory in writing. Putting every adjective after the noun and writing when it should be . And forgetting the irregular masculine-before-vowel forms - is wrong, it's .
