Next, let's explore further what the function of adjectives is. In communication or literature, adjectives always maintain an undeniable importance. Adjectives are often used with verbs and nouns to describe more about the nature, characteristics, and extent of an object, event, or person.

Adjectives not only enrich the message but also help the listener or reader understand more about the mentioned object or event, and at the same time, they make the expression more flexible. There are several main functions of adjectives in a sentence, including:
- Adjectives add meaning to nouns (often in predicate position)
- Adjectives in subject or predicate positions.
Types of Adjectives
Being one of the significant parts of speech, apart from understanding what adjectives are, you also need to grasp how to classify them. In reality, there are various methods to classify adjectives in grammar.
Adjectives can be divided into two categories:
- Adjectives express characteristics of objects, phenomena, or describe actions. Examples: stable, intact, perfect, persistent, challenging, simple...
- Adjectives express characteristics of people, objects, phenomena, or describe nouns referring to people, objects, or phenomena with those characteristics. Examples: youthful, mature, secretive, fresh...
However, this classification method sometimes becomes complex and difficult to understand. Therefore, adjectives are often categorized into types.
Adjectives of State
Adjectives of state depict the current condition of an object or individual, existing within a specific period. Thus, state-describing adjectives are the words that most clearly reflect all states of humans, objects, or phenomena. Common state-describing words include: happy, sad, painful, tired, peaceful, or noisy...

Adjectives of Characteristics
These are adjectives used to describe distinctive features of an object or phenomenon. These characteristics are often inherent traits of an entity such as humans, animals, objects, plants, etc. Using adjectives to describe helps listeners or readers easily visualize differences in shape, color, smell, taste, and other characteristics.
These characteristics can be divided into two main types:
- External characteristics: These are distinctive features of an object or phenomenon, recognized through sensory perceptions such as sight, touch, and taste, through factors like color, shape, and sound.
- Internal characteristics (or adjectives of quality): These are distinct traits that require observation combined with inference, abstraction, and various other cognitive factors for recognition. This includes characteristics of temperament, psychology, personality of an individual, as well as durability and value of an object.
Adjectives of Degree in Vietnamese
Expressing the degree of an action or event in a sentence, degree adjectives such as fast, slow, far, near, superficial,... are common. Apart from the two classification methods mentioned, there's another way to classify adjectives:
- Independent adjectives: This is a group of vocabulary expressing characteristics such as color, scale, shape, sound, degree... In general, these characteristics can stand alone and describe specifically about an object, phenomenon.
- Dependent adjectives: Conversely, dependent adjectives are words that are not inherently adjectives, they belong to other word classes like nouns or verbs, however, they have the ability to change class and are used as adjectives to describe the characteristics or states of an object, creating flexibility in language.
Identifying Adjectives

Position of Adjectives
Through the information presented earlier, we can see that in Vietnamese, adjectives typically come after nouns. However, when an adjective functions as the subject, the predicate usually comes after the adjective.
