Lesson: Types of Sentences by Communicative Intent (Thai Language Usage)

Hello everyone! Today, we are going to summarize the topic of "Types of Sentences by Communicative Intent," which is a frequently tested subject in the A-Level Thai exam. This might seem simple because we use these sentences in our daily lives, but the exam often includes "traps" that can easily confuse you.

If you feel like Thai language is difficult at first, don't worry! The heart of this lesson isn't just about memorization; it's about "reading the speaker's mind" to understand why they said what they said. If you understand the intent, you can easily score points in this section!

1. Informative Sentences (Declarative Sentences)

These are sentences where the speaker's intent is to "inform" or "narrate" something for the listener to know. They do not require an answer and are not meant to command anyone to do anything.

Key Characteristics:
  • States facts, events, or feelings.
  • Includes both affirmative (general statements) and negative forms (often containing words like mai (ไม่), mai dai (ไม่ได้), mi dai (มิได้)).
Examples:

- The weather is very hot today. (Expressing a feeling/fact)
- P'Tae is reading to prepare for the A-Level exam. (Narrating an event)
- I am not hungry. (Negative statement)

Important Point: Remember that negative sentences are a type of informative sentence because the intent is simply to let someone know that "something is not done" or "it is not the case."

2. Interrogative Sentences (Questions)

These are sentences where the speaker's intent is "to seek an answer" to something they are curious about.

Key Characteristics:

They often contain question words such as who (ใคร), what (อะไร), where (ที่ไหน), when (เมื่อไร), how (อย่างไร), why (เหตุใด), or/not (หรือไม่), mai (ไหม).

Examples:

- Who broke the glass? (Seeking a person as the answer)
- Are you going to travel with us? (Seeking a 'yes' or 'no' response)

Watch out! Exam Traps (Questions that don't need answers):

Sometimes a sentence contains question words (who, what) but the intent isn't to ask for an answer; rather, it's to make a statement or express a complaint. For example:
- Anyone (ใคร ๆ) likes eating delicious food. (Meaning: Everyone likes it—this is an informative sentence.)
- I can eat anything (อะไร). (Meaning: I can eat everything—this is an informative sentence.)

Did you know? A-Level exams often feature what are called "Rhetorical Questions," which are questions where the speaker already knows the answer or asks to be sarcastic. For example: "Is doing this a good idea?" The actual intent is to say "It's not good." So, always read the context carefully!

3. Imperative Sentences (Commands and Requests)

These are sentences where the speaker's intent is "to get the listener to do something."

Divided into 3 sub-types:

1. Commands: Telling someone to do something. Usually includes words like jong (จง), hai (ให้), tong (ต้อง).
- Select (จงเลือก) the most correct answer.

2. Prohibitions: Usually includes words like ya (อย่า), ham (ห้าม).
- Do not (ห้าม) make noise in the library.

3. Requests/Suggestions: A polite way of asking someone to act. Usually includes words like karuna (กรุณา), prod (โปรด), chuay (ช่วย), wan (วาน), gan-ter (กันเถอะ).
- Please (กรุณา) take off your shoes before entering the room.
- Let's go eat (กันเถอะ).

Memory Trick: If you read a sentence and feel that you "need to move" or "need to change your behavior" based on what was said, that is an imperative sentence!

Common Mistakes

Many students get tricked by the "sentence structure" and forget to look at the "true intent." Remember:

  • Questions without answers: e.g., "Who knows?" (The intent is to inform that no one knows = Informative).
  • Declarative sentences with question words: e.g., "You can eat anything (อะไร) you want." (The intent is to inform that you have a choice = Informative).
  • Requests using question structure: e.g., "Can you help me open the door?" (The intent is to have someone open the door = Imperative/Request).

Key Takeaway

To identify the type of sentence by intent, consider the "result the speaker desires":

1. Informative: Wants the listener to "receive knowledge" (Facts/Information).
2. Interrogative: Wants the listener to "provide information" (Answer needed).
3. Imperative: Wants the listener to "take action/stop an action" (Action needed).

Important Point: When taking the exam, read the sentence and imagine if someone said this to you, what would you have to do in response? If you just nod to acknowledge = Informative, if you have to answer = Interrogative, and if you have to move or act = Imperative.

Good luck! This section is easy to score points in. Just stay mindful and analyze the speaker's intent carefully, and your A-Level Thai score will be in the bag!
