Tình thái từ là gì? Cách sử dụng và đặt câu với tình thái từ?


In the realm of Vietnamese grammar, the concept of “tình thái từ” is quite unfamiliar to many individuals. While we are acquainted with terms like subject, verb, and adjective, “tình thái từ” is seldom discussed in educational and professional settings. In this article, we will explore this new concept and its usage in both spoken and written language.

To learn more about “tình thái từ,” let’s dive into its definition and how it can be effectively utilized in various contexts.

What is “Tình Thái Từ”?

Although “tình thái từ” may seem like a novel term, it has been previously mentioned in basic education curriculums. However, due to its infrequent use in communication and writing, it remains unfamiliar to some individuals. In order to dissect the term, we can understand that “tình” refers to emotions, while “thái” signifies the attitude of the language user. With this understanding, we can simplify the definition as follows:

“Tình thái từ” refers to certain words added to a sentence with the purpose of creating expressive nuances. These words are used to construct interrogative, imperative, and exclamatory sentences, as well as to convey the emotions and attitudes of the language user. Typically, these words are positioned at the end of a sentence to emphasize the user’s feelings and attitudes.

To illustrate the role of “tình thái từ,” let’s examine the effect of adding these words to a declarative sentence:

Original Sentence: “Anh về.” (You come back.)

  • “Anh về à? Anh về ư? Anh về hả?” (Are you coming back?) – Interrogative sentence.
  • “Anh về đi! Anh về với!” (Come back!) – Imperative sentence.
  • Adding “tình thái từ” at the end of the sentence:
    • “Anh về nhé!” (Come back, please!) – Indicates affection and intimacy.
    • “Anh về cơ!” (Come back, dear!) – Conveys a sense of cajoling.
    • “Anh về vậy!” (Come back then!) – Exhibits reluctance.
    • “Anh về đây!” (Come back here!) – Emphasizes the command.
    • “Anh không về đâu!” (Don’t come back!) – Demonstrates determination.

Classification of “Tình Thái Từ”

To avoid confusion and facilitate the use of “tình thái từ,” this linguistic construct can be divided into four categories:

  1. Interrogative Words – These words serve as tools to create interrogative sentences (e.g., à, ư, hử, chứ, chăng).

  2. Imperative Words – These words are used to form imperative sentences (e.g., đi, nào, với).

  3. Exclamatory Words – These words function as means to express emphatic exclamations (e.g., thay, sao).

  4. Emotive Words – These words indicate the emotions and attitudes of the speaker (e.g., ạ, nhé, cơ, mà, vậy).

Please note that the aforementioned classification is relative, as some words belonging to the first category (interrogative words) can also convey emotions and attitudes.

Let’s examine some examples:

Example 1:

  • Original Sentence: “Bạn tôi đi làm rồi.” (My friend has gone to work.)
  • When we add “à” at the end of the sentence, it becomes a question: “Bạn tôi đi làm rồi à?” Here, “à” functions as “tình thái từ” to express the user’s skeptical attitude.

Example 2:

  • Original Sentence: “Con nín.” (The child is silent.)
  • When we add “đi” after the sentence, it becomes an exclamation: “Con nín đi!” In this case, “đi” functions as “tình thái từ.”

Functions of “Tình Thái Từ”

In language, both in oral and written communication, “tình thái từ” is frequently used to create interrogative and exclamatory sentences, allowing the speaker to infuse their emotions and attitudes into their words. This is the main function of “tình thái từ.” According to linguistic experts and relevant literature, “tình thái từ” has two important functions:

  1. The first function is to construct sentences based on the user’s intentions. It is manifested through interrogative sentences, such as words like “hả,” “à,” “sao,” and exclamatory sentences, such as “thay,” “sao.” It can also be seen in imperative sentences with words like “nghe,” “đi,” “thôi,” “nhé,” etc. in relation to a certain matter.


  • Original Sentence: “Chiếc ô tô này hỏng rồi sao.” (Is this car broken?) Here, the word “sao” is used as “tình thái từ” to create an interrogative sentence and express the user’s surprise.
  1. The second function of “tình thái từ” is to convey emotional nuances in spoken language. This encompasses:
  • Expressing a sense of doubt or suspicion.
    Example: “Nó có người yêu rồi hả?” (Does he/she already have a partner?) In this sentence, the “tình thái từ” is the word “hả,” which conveys the user’s distrust and doubt about someone they know having a partner.

  • Conveying a tone of surprise or amazement.
    Example: “Có thật công ty sẽ tăng lương không hả chị?” (Is it true that the company will increase salaries, sister?) Here, the “tình thái từ” is the word “hả,” which expresses the user’s astonishment about the news of a salary increase in the company where the sister works.

  • Reflecting expectations or anticipation.
    Example: “Nào ta cùng đi xem phim thôi!” (Let’s go watch a movie, shall we?) In this sentence, the “tình thái từ” is the word “thôi,” which demonstrates the user’s eagerness for the upcoming movie they will watch.

How to Use “Tình Thái Từ”

When using “tình thái từ,” it is important to be subtle and considerate of the various emotional nuances they can convey. Since “tình thái từ” is commonly used in daily communication, it should be employed in a manner appropriate to the context and the person you are interacting with. Here are some specific guidelines:

  • When using “tình thái từ” to show respect and politeness to superiors, you can add the word “ạ” at the end of the sentence.

Example: “Cháu chào ông, cháu chào bà ạ!” (I greet you, sir/madam!)

  • When using “tình thái từ” to express intimacy in relationships of equal footing, you can use words like “à,” “nhé,” etc.

Example: “Chiều nay chúng mình đi du lịch Nha Trang nhé!” (Let’s go on a trip to Nha Trang this afternoon!)

  • When using “tình thái từ” to refer to another person, you can use words like “kia,” “này,” etc.

Example: “Cô ấy rất thích chiếc xe đằng kia!” (She really likes that car over there!)

  • When using “tình thái từ” to express a dismissive attitude, you can use the word “vậy.”

Example: “Thôi cứ tiếp tục làm việc như kế hoạch ban đầu vậy!” (Just continue working according to the original plan, then!)

  • When using “tình thái từ” to express concern or explanation about something, you can use the word “mà.”

Example: “Chị đã bảo em phải làm như vậy rồi mà! Sao em lại không nghe!” (I already told you to do it like that, why didn’t you listen?)

These are just a few examples of how “tình thái từ” can be used in sentences. By following these guidelines, you can effectively incorporate “tình thái từ” into your conversations to enhance your expressions and reflections of emotions.

Differentiating “Tình Thái Từ” from Exclamatory Sentences

Distinctive Characteristics:

  • “Tình thái từ” is primarily placed at the end of a sentence, and it often comprises words such as “à,” “ư,” “hử,” “chứ,” “chăng,” “ạ,” “nhé,” “cơ,” “mà,” “vậy,” etc.

  • Exclamatory sentences, on the other hand, directly express the speaker’s emotions and frequently employ exclamation words such as “Trời ơi,” “Hỡi ơi,” “Ôi,” etc. These sentences generally end with an exclamation mark in written form.

Functional Differences:

  • “Tình thái từ” serves the function of constructing sentences based on the user’s intentions. It exhibits emotional nuances in the user’s speech, such as expressing doubt, surprise, anticipation, and more.

  • Exclamatory sentences function as a direct display of the speaker’s emotions. While the user can convey emotions through different types of sentences (interrogative, imperative, declarative), the exclamation sentence specifically showcases emotions through exclamatory words.

By understanding the characteristics and functions of both “tình thái từ” and exclamatory sentences, you can effectively apply them in your spoken and written communication.


In conclusion, “tình thái từ” plays a significant role in Vietnamese language by enhancing expressions and reflecting emotions and attitudes. By adding these words to sentences, users can create interrogative, imperative, and exclamatory sentences, as well as convey their feelings and attitudes. Understanding the different categories and functions of “tình thái từ” enables individuals to effectively utilize this linguistic construct in various conversational contexts.
