French grammar - Feminine adjectives - doubling the final consonant

Feminine adjectives - doubling the final consonant

As we saw, the general rule is to add -e to make a feminine adjective.

But if the masculine adjective ends with an -n, -s, or -l then we double that final consonant before adding -e to make it feminine.

For example:

bon bonne - 'good' double the -n and add an -e.

gros grosse - 'fat' or 'big' double the -s and add an -e.

gentil gentille - 'nice' or 'kind' double the -l and add an -e.

Examples:
Le pain est très bon mais la tarte n'est pas bonne.
The bread is very good but the pie is not good.

bon (m) means 'good'

bon (m) bonne (f)

pain (m) means 'bread'

tarte (f) means 'pie (usually sweet)'

Est-elle gentille ?
Is she nice?

gentil (m) means 'nice' or 'kind'

gentil (m) gentille (f)
