Types of Sentence

Overview & Fundamental Concept

Exhaustive AISSEE Class 6 English guide for Types of Sentence. Covers Assertive, Interrogative, Imperative, and Exclamatory sentences, structural forms (Simple/Compound/Complex), transformation rules, solved models, and 10 practice drills.

• A Sentence is a grammatically complete group of words containing a subject and a finite predicate, expressing a complete thought.
• 1. Declarative / Assertive Sentence: Makes a statement, asserts a fact, or shares information. Ends with a full stop (period, .).
• • Affirmative: States a positive fact (e.g., 'The sun rises in the east.').
• • Negative: Contains negative words (not, never, no) stating a denial (e.g., 'He does not waste his study hours.').
• 2. Interrogative Sentence: Asks a direct question to elicit information. Always terminates with a question mark (?).
• • Wh- Questions: Begin with interrogative pronouns/adverbs (Who, What, Where, When, Why, Which, How) and demand detailed factual answers.
• • Yes/No Questions: Begin with an auxiliary verb (Is, Are, Do, Does, Did, Have, Can, Will) and require a simple affirmative or negative answer.
• 3. Imperative Sentence: Expresses an order, command, request, advice, prohibition, or instruction. Usually terminates with a full stop (or exclamation mark for urgent commands).
• • The Implied Subject Law: The subject of an imperative sentence is almost always the second person pronoun 'You', which is omitted/implied (e.g., '[You] Stand at ease!', '[You] Please lend me your notebook.').
• 4. Exclamatory Sentence: Expresses sudden, strong emotions, feelings, or surprise (joy, sorrow, wonder, shock, anger). Always ends with an exclamation mark (!).
• • Frequently begins with 'What a/an...' (before noun phrases: 'What a brave soldier he is!') or 'How...' (before adjectives/adverbs: 'How beautiful the rainbow looks!').

• Sentences are also classified based on their underlying clause architecture:
• Clause Basics: A clause has a subject and a finite predicate. An Independent (Main) Clause makes complete sense on its own. A Dependent (Subordinate) Clause cannot stand alone.
• 1. Simple Sentence: Contains exactly ONE independent clause with one finite verb (e.g., 'The brave cadet completed the obstacle course.'). It may contain compound subjects or non-finite phrases, but only one finite verb.
• 2. Compound Sentence: Contains TWO OR MORE independent clauses of equal grammatical rank, joined by a coordinating conjunction.
• • The FANBOYS Conjunctions: For, And, Nor, But, Or, Yet, So (e.g., 'Rohan studied hard, and he topped the examination.', 'The weather was bad, yet the flight landed safely.').
• 3. Complex Sentence: Contains ONE independent clause and AT LEAST ONE dependent (subordinate) clause, joined by a subordinating conjunction.
• • Subordinating conjunctions: because, although, though, since, unless, until, while, where, when, if, after, before, that, which, who (e.g., 'We cannot play outside because it is raining heavily.').

• In AISSEE, transformation of sentences requires converting a sentence from one form to another WITHOUT altering its core meaning.
• Affirmative to Negative Transformation: Must use a negative word paired with an antonym, or a double negative structure:
• • 'Rohan is wise.' -> 'Rohan is not foolish.' (Meaning preserved).
• • 'As soon as the teacher entered, the boys stood up.' -> 'No sooner did the teacher enter than the boys stood up.'
• • 'Only cadets can enter.' -> 'None but cadets can enter.'
• Assertive to Interrogative Transformation: Invert polarity during transformation so the assertion remains identical (Rhetorical Questioning):
• • Positive Assertive -> Negative Question: 'Everyone loves his motherland.' -> 'Who does not love his motherland?' (or 'Does anyone not love his motherland?').
• • Negative Assertive -> Positive Question: 'No one can defeat destiny.' -> 'Can anyone defeat destiny?' (or 'Who can defeat destiny?').
• Exclamatory to Assertive Transformation: Remove emotional markers and insert intensifying adverbs like very, truly, great, wonderful:
• • 'What a beautiful painting!' -> 'It is a very beautiful painting.'
• • 'How cold the night is!' -> 'The night is extremely cold.'
• • 'Alas! We lost our great leader.' -> 'It is extremely sorrowful that we lost our great leader.'
• Removal of 'Too... to': Replace 'too' with 'so', and 'to + verb' with 'that + subject + cannot/could not':
• • 'The box is too heavy for me to lift.' -> 'The box is so heavy that I cannot lift it.'
• • 'He was too weak to run.' -> 'He was so weak that he could not run.'

• Mastering word order and terminal punctuation is the fastest way to categorize sentences in exam drills:
• Inverted Question Word Order: While declarative sentences follow Subject + Verb + Object (S-V-O), interrogative sentences invert word order: Auxiliary Verb + Subject + Main Verb (e.g., 'Are you coming?', 'Did they win?').
• Indirect Questions are NOT Interrogative: Sentences that report a question in indirect speech follow declarative order and end with a full stop: 'He asked me where I was going.' (NOT 'He asked me where was I going?').
• Imperatives with Polite Wrappers: Words like 'Please', 'Kindly', and 'May I request you to' do not change the imperative nature of the core sentence.
• Exclamatory Inversion: In exclamations, the verb often moves to the very end of the sentence: 'What a fine player he is!' (Subject 'he' + Verb 'is' at the end).
