The adjective gives a more detailed description to a noun.
A red car.
The little man.
His soft voice.
There are two different ways of using an adjective, in an attributive or a predicative way. In praxis this means that the adjective is used together with (attributive) or without (predicative) a noun.
Attributive use
Le
jeune
homme
dort.
The
young
man
sleeps.
Il
a
une
petite
maison.
He
has
a
little
house.
Il
aime
les
bons
vins.
He
likes
the
good
wines.
Predicative use
La
maison
est
grande.
The
house
is
big.
Les
voitures
sont
chères.
The
cars
are
expensive.
Le
temps
est
mauvais.
The
weather
is
bad.
This all does not sound too bad. Now, here comes the clou: In French there is a differentiation also in the adjective regarding the gender and the number of the noun. We will discuss this more in detail in the following chapter.
