An adjective serves to specify the noun. It gives a quality, a state, a form, a color, or an appreciation/assessment of a person, an object, or an idea. In a red dress, red describes dress. In calm children, calm describes children. The adjective agrees with the noun in gender and number, as in Agreement of the Adjective. We say an interesting book, an interesting story, interesting books, interesting stories.

Function and agreement of the adjective

Idea
An adjective describes the noun with an idea of quality, size, or mood.
The adjective agrees in gender and number with the noun it accompanies.

In most cases, the adjective follows the noun. The usual structure is noun + adjective. We say a big house, a funny movie, new shoes. This position is the most frequent for adjectives that describe an objective or visible characteristic. If the noun is already determined by an article, a demonstrative or another determiner, the adjective still comes after the noun: this small shop follows another rule, but this old shop keeps the order noun + adjective.

Position after the noun

Idea
In French, the adjective is often placed after the noun.

Some short and very common adjectives are placed before the noun. They are often encountered with size, age, beauty, goodness, and simple quantity. We say a big tree, a small room, a young man, an beautiful evening, a good meal, a bad movie. These adjectives form very common groups with the noun, and their place before the noun is part of normal usage. With Formation of the Adjective, we more easily identify the form of these words, then we learn their usual place in the sentence.

Adjectives before the noun

Idea
Some short and frequent adjectives are placed before the noun.
Small is often placed before the noun in everyday language.
Big is often placed before the noun when it is very common.

With certain adjectives, placement changes the meaning. Before the noun, the adjective often gives a more subjective or more general idea. After the noun, it describes more a concrete quality. We say a great man to talk about an important person, but a tall man to talk about his height. We say an ancient professor to talk about a professor from the past, but an old professor to talk about a professor aged. The decision depends on the sense the speaker wants to convey.

Shift in meaning according to position

Idea
The place of certain adjectives changes their meaning.
With cher, the position often changes the idea expressed.

When several adjectives accompany the same noun, we place first the idea that is more general or more subjective, then the more precise adjective. We can have noun + short adjective + descriptive adjective, or adjective before the noun + noun + adjective after the noun. We say a pretty little white house. Pretty expresses an appreciation, little gives a size, white gives a color. The order follows the logic of description: first judgment, then the characteristic, then the material detail. With Qualifying adjectives, these sense values appear in common usage.

Organization of several adjectives

Idea
When several adjectives surround the same noun, frequency and subjectivity guide the order.
We often place the appreciation before the precision.

Color adjectives generally follow the noun. We say a black car, green gloves, a blue sky. They function as ordinary descriptive adjectives and thus come after the noun in the sentence. When they are compound, they also keep this place: a light blue dress, dark green walls. With Agreement of the Adjective, we also check their agreement with the noun they describe.

Use of color adjectives

Idea
Color adjectives are generally placed after the noun.
They serve to paint a precise image of the noun.

Compound adjectives keep a stable order. They are often found with colors, shapes or precise relations: blue light, dark gray, South American, tiny. In fixed expressions, the order does not change depending on the context. We say a prime minister, a railway line, a safe, a potato. These groups are memorized as blocks. They are often encountered with Demonstrative adjectives, Indefinite adjectives, Numeral adjectives or Relative adjectives when the noun is part of a longer noun phrase.

Compound forms and fixed expressions

Idea
Compound adjectives keep a more stable order.
Fixed expressions repeat themselves without changing the order.
