What makes one sentence a question while another gives a command? Why do some sentences express strong emotion while others simply state a fact? This lesson, crafted for Class 6 and 7 students, explores the four essential types of sentences: Assertive, Interrogative, Imperative, and Exclamatory. You'll learn to identify each type, understand their structures, and transform one type into another — a skill that builds a rock‑solid foundation for all future writing and grammar.

1. What are the Types of Sentences?
We use different kinds of sentences depending on what we want to say. Some sentences give information, some ask questions, some give orders, and some show strong feelings. Based on their function, all sentences can be divided into four main types: Assertive, Interrogative, Imperative, and Exclamatory. Knowing these types helps you not only in grammar exams but also in writing with the right tone.
• Assertive: States a fact or opinion. (The sun rises in the east.)
• Interrogative: Asks a question. (Where do you live?)
• Imperative: Gives a command or makes a request. (Please sit down.)
• Exclamatory: Expresses strong feeling. (What a beautiful painting!)
2. Assertive / Declarative Sentences
An assertive sentence, also called a declarative sentence, simply states a fact, an opinion, or a piece of information. It ends with a full stop (.). Assertive sentences can be affirmative (positive) or negative.
- Affirmative: The children are playing in the garden.
- Negative: The children are not playing in the garden.
- Affirmative: Sheela completed her homework on time.
- Negative: Sheela did not complete her homework on time.
Most of the sentences we speak and write every day are assertive sentences.
3. Interrogative Sentences
An interrogative sentence asks a question. It ends with a question mark (?). There are two main kinds of interrogative sentences:
- Yes/No questions: These begin with a helping verb and can be answered with a simple 'yes' or 'no'.
Example: Do you like chocolate? (Answer: Yes, I do. / No, I don't.) - Wh‑questions: These begin with question words like what, where, when, why, who, whom, which, how.
Example: Where does your uncle live?
Interrogative sentences often invert the subject and the helping verb. "She is happy." becomes "Is she happy?"
4. Imperative Sentences
An imperative sentence gives a command, makes a request, or offers advice. The subject 'you' is usually hidden because the sentence is directed at the listener. It can end with a full stop (.) or, for urgent commands, with an exclamation mark (!).
- Command: Stand up straight.
- Request: Please pass me the salt.
- Advice: Take care of your health.
Imperative sentences can also be negative. "Do not run in the corridor."
5. Exclamatory Sentences
An exclamatory sentence expresses strong feelings like surprise, joy, anger, or wonder. It always ends with an exclamation mark (!). These sentences often begin with 'What' or 'How', though not always.
- What a lovely dress you are wearing!
- How tall you have grown!
- Oh, I spilled the milk!
Note: Sometimes an imperative sentence can also end with an exclamation mark if the command is very strong ("Get out!"), but it remains an imperative sentence.
6. Transforming One Type into Another
In exams, you are often asked to change sentences from one type to another without changing the meaning. Here are the general rules:
- Assertive to Interrogative: Move the helping verb before the subject. "He is kind." → "Is he not kind?"
- Assertive to Exclamatory: Use 'How' or 'What' and an exclamation mark. "This is a pleasant scene." → "What a pleasant scene this is!"
- Assertive to Imperative: Use 'You are ordered/requested/advised to...' "You should help the poor." → "Please help the poor."
Practise these transformations using the solved examples below.
7. Solved Examples (5)
Show Solution
Explanation: The sentence makes a polite request. The subject 'you' is understood. The sentence begins with 'Please' and ends with a full stop, characteristic of an imperative.
Show Solution
Explanation: The helping verb 'can' is moved to the beginning of the sentence, before the subject 'she'. The full stop is replaced by a question mark. The meaning remains the same.

Show Solution
Explanation: The sentence begins with the helping verb 'Is' and ends with a question mark. It asks a question and can be answered with Yes or No. Hence, it is a Yes/No interrogative sentence.
Show Solution
Explanation: The exclamatory sentence beginning with 'How' is transformed by removing 'How' and the exclamation mark, and using 'very' before the adjective. The subject‑verb order is restored.

Why Mastering Sentence Types Makes You a Better Writer
When you know the four types of sentences, you gain control over your writing. You can ask questions to engage your reader, use commands to direct them, express emotions to connect with them, and state facts to inform them. This variety makes your paragraphs and stories interesting. Students who consciously use different sentence types in their essays and letters score higher because their writing feels alive, not flat. Practise by taking a simple paragraph and underlining each sentence by type — you'll quickly see how the best writers mix them for effect.
