What is a Sentence?
A sentence is a fundamental unit of language that expresses a complete thought. It typically contains a subject (who or what the sentence is about) and a predicate (what the subject does or is).
A sentence begins with a capital letter and ends with a punctuation mark, such as a period (.), a question mark (?), an exclamation point (!), or, in some cases, an ellipsis (…). Understanding the components and structure of a sentence is crucial for effective communication.
Sentences can be classified based on their purpose and structure. The four primary types of sentences are declarative, interrogative, imperative, and exclamatory.
Each type serves a different function in communication, allowing us to make statements, ask questions, give commands, and express strong emotions. The ability to identify and use each type appropriately is essential for clear and impactful writing and speaking.
Structural Breakdown of a Sentence
The basic structure of a sentence revolves around the subject and the predicate. The subject is the noun or pronoun that performs the action or is being described. The predicate contains the verb and everything that follows it, describing what the subject does or is. Let’s delve deeper into the key components:
- Subject: The subject is the main focus of the sentence. It can be a noun (dog, Mary, freedom), a pronoun (he, she, it, they), or a noun phrase (the old man, a bright student).
- Predicate: The predicate includes the verb and all the words that modify or complement it. It tells us something about the subject. A predicate always contains a verb.
- Verb: The verb is the action word or state of being in the sentence. It indicates what the subject is doing or what state it is in (run, is, feel, become).
- Object: An object receives the action of the verb. There are two types: direct objects (receiving direct action) and indirect objects (receiving the direct object).
- Complement: A complement provides more information about the subject or object. Subject complements follow linking verbs (is, are, was, were, become). Object complements follow direct objects.
- Modifier: Modifiers describe or limit other words in the sentence. Adjectives modify nouns, and adverbs modify verbs, adjectives, or other adverbs.
Consider the sentence: “The cat chased the mouse quickly.” Here, “The cat” is the subject, “chased the mouse quickly” is the predicate, “chased” is the verb, “the mouse” is the direct object, and “quickly” is the adverb modifying the verb “chased.”
Sentences can also include phrases and clauses. A phrase is a group of related words that does not contain both a subject and a verb. A clause contains both a subject and a verb. There are two types of clauses: independent clauses (which can stand alone as a sentence) and dependent clauses (which cannot stand alone and must be connected to an independent clause).
Types of Sentences
English has four main types of sentences, each with a specific purpose and structure. Understanding these types is essential for constructing clear and varied writing.
Declarative Sentences
A declarative sentence makes a statement. It provides information or expresses an opinion.
It ends with a period (.). The typical word order is subject-verb-object.
Examples of declarative sentences include:
- The sun is shining.
- I enjoy reading novels.
- She is a talented musician.
- They live in New York City.
- My favorite color is blue.
Declarative sentences are the most common type of sentence and are used to convey facts, observations, and opinions. They form the foundation of most writing and conversation.
Interrogative Sentences
An interrogative sentence asks a question. It ends with a question mark (?). Interrogative sentences often begin with question words such as who, what, where, when, why, how, or with auxiliary verbs such as is, are, was, were, do, does, did, have, has, had.
Examples of interrogative sentences include:
- What is your name?
- Where do you live?
- Are you coming to the party?
- Have you finished your homework?
- Why are you so late?
Interrogative sentences are used to seek information, clarify understanding, and engage in conversation.
Imperative Sentences
An imperative sentence gives a command or makes a request. It often omits the subject, which is understood to be “you.” It usually ends with a period (.), but can end with an exclamation point (!) for emphasis.
Examples of imperative sentences include:
- Close the door.
- Please be quiet.
- Do your homework.
- Come here.
- Be careful!
Imperative sentences are used to direct actions, give instructions, and make polite requests.
Exclamatory Sentences
An exclamatory sentence expresses strong emotion or surprise. It ends with an exclamation point (!).
These sentences are used to convey excitement, anger, joy, or other intense feelings. They are often shorter and more impactful than other types of sentences.
Examples of exclamatory sentences include:
- That’s amazing!
- I can’t believe it!
- What a beautiful day!
- Help!
- How exciting!
Exclamatory sentences are used to add emphasis and emotion to your writing or speech.

Sentence Usage Rules
Proper sentence construction follows specific grammatical rules. Here are some key rules to keep in mind:
- Subject-Verb Agreement: The verb must agree in number with the subject. If the subject is singular, the verb must be singular. If the subject is plural, the verb must be plural. For example: “He is” (singular) vs. “They are” (plural).
- Pronoun Agreement: Pronouns must agree in number and gender with their antecedents (the nouns they refer to). For example: “The girl likes her doll.”
- Correct Tense: Use the correct verb tense to indicate when the action takes place (past, present, future). Be consistent with tense throughout a sentence or paragraph.
- Clear Pronoun Reference: Ensure that pronouns have clear and unambiguous references to their antecedents. Avoid vague pronoun references.
- Parallel Structure: When listing items or ideas, use parallel structure. This means using the same grammatical form for each item. For example: “I enjoy reading, writing, and hiking” (all gerunds).
- Avoid Sentence Fragments: A sentence fragment is an incomplete sentence that lacks a subject or a verb, or does not express a complete thought. Ensure all sentences have both a subject and a verb and express a complete idea.
- Avoid Run-on Sentences: A run-on sentence combines two or more independent clauses without proper punctuation or conjunctions. Separate the clauses with a period, semicolon, or conjunction.
There are some exceptions to these rules, particularly in informal writing or speech. However, adhering to these rules will ensure clarity and correctness in most formal contexts.
Common Mistakes in Sentence Construction
Even experienced writers make mistakes in sentence construction. Here are some common errors to watch out for:
Table 5: Common Mistakes and Corrections
This table presents common sentence construction mistakes alongside their corrections, highlighting the importance of proper grammar and syntax.
| Mistake | Incorrect Example | Correct Example | Explanation |
|---|---|---|---|
| Subject-Verb Disagreement | The dogs is barking loudly. | The dogs are barking loudly. | The verb “is” does not agree with the plural subject “dogs.” |
| Pronoun Agreement Error | Everyone should bring their book. | Everyone should bring his or her book. / All students should bring their books. | “Everyone” is singular, but “their” is plural. Using “his or her” or rephrasing to “all students” corrects the error. |
| Incorrect Tense | I will went to the store yesterday. | I went to the store yesterday. | “Will went” is an incorrect verb tense. The past tense of “go” is “went.” |
| Vague Pronoun Reference | The car was parked near the tree, which was old. | The car, which was old, was parked near the tree. / The old tree was near the parked car. | It’s unclear whether “which” refers to the car or the tree. |
| Lack of Parallel Structure | I enjoy swimming, hiking, and to read. | I enjoy swimming, hiking, and reading. | The items in the list should have the same grammatical structure (all gerunds). |
| Sentence Fragment | Because it was raining. | Because it was raining, we stayed inside. | “Because it was raining” is a dependent clause and cannot stand alone as a sentence. |
| Run-on Sentence | I went to the store I bought some milk. | I went to the store, and I bought some milk. / I went to the store; I bought some milk. | Two independent clauses are joined without proper punctuation or a conjunction. |
| Misplaced Modifier | Covered in mud, I saw the dog. | I saw the dog covered in mud. | The modifier “covered in mud” should be closer to the noun it modifies (the dog). |
| Dangling Modifier | After eating dinner, the dishes were washed. | After eating dinner, I washed the dishes. | The modifier “after eating dinner” has no clear subject performing the action. |
| Incorrect Word Choice | Their going to the party. | They’re going to the party. | “Their” is a possessive pronoun, while “they’re” is a contraction of “they are.” |
| Double Negative | I don’t have no money. | I don’t have any money. / I have no money. | Using two negative words in the same clause creates a positive meaning. |
| Comma Splice | I went to the store, I bought some milk. | I went to the store, and I bought some milk. / I went to the store; I bought some milk. | Two independent clauses are joined only by a comma, which is incorrect. |
| Incorrect Use of Apostrophe | The dog’s are barking. | The dogs are barking. | “Dog’s” indicates possession, while “dogs” is the plural form. |
| Mixing Up “Its” and “It’s” | The dog wagged it’s tail. | The dog wagged its tail. | “Its” is a possessive pronoun, while “it’s” is a contraction of “it is.” |
| Using “Affect” Instead of “Effect” | The weather will effect our plans. | The weather will affect our plans. | “Affect” is a verb meaning to influence, while “effect” is a noun meaning a result. |
| Using “Then” Instead of “Than” | I am taller then you. | I am taller than you. | “Then” is used to indicate time, while “than” is used for comparisons. |
| Using “To” Instead of “Too” | I am going to the store, to. | I am going to the store, too. | “To” indicates direction, while “too” means also or excessively. |
| Misusing “There,” “Their,” and “They’re” | Their going to go over their. | They’re going to go over there. | “There” indicates a place, “their” is a possessive pronoun, and “they’re” is a contraction of “they are.” |
| Using “Your” Instead of “You’re” | Your going to be late. | You’re going to be late. | “Your” is a possessive pronoun, while “you’re” is a contraction of “you are.” |
| Incorrect Comma Usage | I like apples oranges and bananas. | I like apples, oranges, and bananas. | Commas should be used to separate items in a list. |

Advanced Topics in Sentence Structure
For advanced learners, exploring complex sentence structures can enhance writing sophistication and clarity. Some advanced topics include:
- Complex Sentences: Sentences containing one independent clause and one or more dependent clauses.
- Compound Sentences: Sentences containing two or more independent clauses joined by a coordinating conjunction or a semicolon.
- Compound-Complex Sentences: Sentences containing two or more independent clauses and one or more dependent clauses.
- Subordination and Coordination: Using these techniques to create varied and interesting sentence structures.
- Rhetorical Devices: Employing techniques like parallelism, antithesis, and chiasmus to enhance the impact of sentences.
Understanding these advanced concepts allows for more nuanced and effective communication.
Frequently Asked Questions (FAQ)
- What is the difference between a phrase and a clause?
A phrase is a group of related words that does not contain both a subject and a verb. A clause, on the other hand, contains both a subject and a verb. For example, “after the game” is a phrase, while “after the game ended” is a clause.
- How can I identify the subject and predicate in a sentence?
To identify the subject, ask yourself “Who or what is the sentence about?” The answer is the subject. The predicate includes the verb and everything that follows it, describing what the subject does or is. For instance, in the sentence “The dog barked loudly,” the subject is “The dog” and the predicate is “barked loudly.”
- What is a run-on sentence and how can I fix it?
A run-on sentence combines two or more independent clauses without proper punctuation or conjunctions. To fix it, you can separate the clauses with a period, a semicolon, or a comma followed by a coordinating conjunction (and, but, or, nor, for, so, yet). Example: Incorrect: “I went to the store I bought some milk.” Correct: “I went to the store, and I bought some milk.”
- What is a sentence fragment and how can I avoid it?
A sentence fragment is an incomplete sentence that lacks a subject or a verb, or does not express a complete thought. To avoid it, ensure that every sentence has both a subject and a verb and expresses a complete idea. Example: Incorrect: “Because it was raining.” Correct: “Because it was raining, we stayed inside.”
- How do I use commas correctly in a sentence?
Commas have several uses, including separating items in a list, setting off introductory phrases or clauses, and joining independent clauses with a coordinating conjunction. For example: “I like apples, oranges, and bananas.” “After the game, we went home.” “I went to the store, and I bought some milk.”
