Welcome to French adjectives! French adjectives are words that describe nouns, and they have special rules. The most important rule is that adjectives must agree with the noun they describe in both gender - masculine or feminine - and number - singular or plural. Most French adjectives are placed after the noun, but some common adjectives come before the noun.
Now let's look at gender and number agreement. French adjectives must change their form to match the noun they describe. For example, the adjective 'black' changes depending on whether the noun is masculine or feminine, singular or plural. Masculine singular is 'noir', feminine singular adds an 'e' to become 'noire', masculine plural adds an 's' to become 'noirs', and feminine plural adds both 'e' and 's' to become 'noires'.
Most French adjectives follow the general rule of being placed after the noun they describe. This is the opposite of English, where adjectives usually come before the noun. For example, we say 'une maison blanche' meaning 'a white house', with 'blanche' coming after 'maison'. Similarly, 'un livre interessant' means 'an interesting book', with the adjective 'interessant' following the noun 'livre'. This pattern applies to most descriptive adjectives in French.
