Definition of Declarative Sentences

A declarative sentence is a type of sentence that makes a statement. Its primary function is to convey information, express an opinion, or describe a fact. Unlike interrogative sentences (which ask questions), imperative sentences (which give commands), or exclamatory sentences (which express strong emotion), declarative sentences simply declare something. They are the most common type of sentence in the English language and are essential for everyday communication.

Declarative sentences typically follow a standard subject-verb order. The subject is who or what the sentence is about, and the verb describes the action or state of being of the subject.

This straightforward structure makes declarative sentences easy to recognize and understand. They always end with a period (.).

Classification of Declarative Sentences

Declarative sentences can be further classified based on their complexity. Here are the main categories:

• Simple Declarative Sentences: These sentences contain one independent clause (a clause that can stand alone as a complete sentence).
• Compound Declarative Sentences: These sentences contain two or more independent clauses joined by a coordinating conjunction (e.g., and, but, or, nor, for, so, yet) or a semicolon.
• Complex Declarative Sentences: These sentences contain one independent clause and one or more dependent clauses (clauses that cannot stand alone as a complete sentence).
• Compound-Complex Declarative Sentences: These sentences contain two or more independent clauses and one or more dependent clauses.

Function of Declarative Sentences

The primary function of a declarative sentence is to make a statement. This statement can be about anything – a fact, an opinion, an observation, or a belief.

Declarative sentences are used to:

• Provide information: “The capital of France is Paris.”
• Express opinions: “I think that movie was excellent.”
• Describe events: “It rained heavily yesterday.”
• State facts: “The Earth revolves around the Sun.”
• Share beliefs: “I believe in the power of education.”

Contexts for Using Declarative Sentences

Declarative sentences are applicable in nearly all contexts, from casual conversations to formal writing. They are used in:

• Everyday conversations: “I’m going to the store.”
• Academic writing: “The study found a significant correlation between exercise and mental health.”
• News reports: “The president announced a new economic policy.”
• Fiction writing: “The old house stood on a hill overlooking the town.”
• Business communications: “We have received your payment.”

Structural Breakdown

The basic structure of a declarative sentence follows the Subject-Verb-Object (SVO) pattern, although variations exist depending on the sentence’s complexity.

Subject

The subject is the noun or pronoun that performs the action or is being described. It typically appears at the beginning of the sentence.

Example: The dog barked loudly.

Verb

The verb expresses the action or state of being of the subject.

Example: The dog barked loudly.

Object

The object receives the action of the verb. It can be a direct object (receiving the action directly) or an indirect object (receiving the action indirectly).

Example (Direct Object): The dog chased the ball.

Example (Indirect Object): She gave him the book.

Complements

Complements provide additional information about the subject or object. Subject complements follow linking verbs (e.g., be, seem, become) and describe the subject.

Object complements follow direct objects and describe the object.

Example (Subject Complement): She is a doctor.

Example (Object Complement): They elected him president.

Modifiers

Modifiers add detail and description to the subject, verb, or object. They can be adjectives, adverbs, phrases, or clauses.

Example: The small dog barked loudly.

Types and Categories of Declarative Sentences

Declarative sentences can be categorized based on their structure and purpose. Understanding these categories helps to improve sentence construction and overall writing clarity.

Simple Declarative Sentences

A simple declarative sentence contains one independent clause. It has a subject and a verb and expresses a complete thought.

Example: The sun shines.

Compound Declarative Sentences

A compound declarative sentence contains two or more independent clauses joined by a coordinating conjunction (and, but, or, nor, for, so, yet) or a semicolon.

Example: The sun shines, and the birds sing.

Complex Declarative Sentences

A complex declarative sentence contains one independent clause and one or more dependent clauses. A dependent clause cannot stand alone as a sentence.

Example: Because the sun shines, the birds sing.

Compound-Complex Declarative Sentences

A compound-complex declarative sentence contains two or more independent clauses and one or more dependent clauses.

Example: Because the sun shines, the birds sing, and the flowers bloom.

Usage Rules for Declarative Sentences

Using declarative sentences correctly involves understanding several key rules. These rules ensure clarity, accuracy, and effective communication.

Subject-Verb Agreement

The verb in a declarative sentence 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.

Correct: The dog barks.

Incorrect: The dog bark.

Correct: The dogs bark.

Incorrect: The dogs barks.

Tense Consistency

Maintain consistent verb tense within a sentence and throughout a paragraph. Shifting tenses unnecessarily can confuse the reader.

Correct: I went to the store and bought milk.

Incorrect: I went to the store and buy milk.

Proper Punctuation

Declarative sentences always end with a period (.). Ensure that you use proper punctuation to indicate the end of the sentence.

Correct: The sky is blue.

Incorrect: The sky is blue

Avoiding Sentence Fragments

A sentence fragment is an incomplete sentence that lacks a subject or a verb or does not express a complete thought. Ensure that your declarative sentences are complete and express a clear idea.

Fragment: Because it was raining.

Complete Sentence: Because it was raining, I stayed inside.

Avoiding Run-on Sentences

A run-on sentence occurs when two or more independent clauses are joined without proper punctuation or conjunctions. To correct a run-on sentence, separate the clauses with a period, semicolon, or coordinating conjunction.

Run-on: The sun was shining the birds were singing.

Correct: The sun was shining. The birds were singing.

Correct: The sun was shining, and the birds were singing.

Common Mistakes with Declarative Sentences

Even experienced writers can make mistakes with declarative sentences. Being aware of these common errors can help you improve your writing.

The table below illustrates some common mistakes made while writing declarative sentences, along with the corrected versions and explanations.

Mistake	Incorrect Example	Correct Example	Explanation
Subject-Verb Agreement	The cat eat fish.	The cat eats fish.	The verb must agree with the singular subject “cat.”
Tense Inconsistency	I went to the store and will buy milk.	I went to the store and bought milk.	Maintain consistent past tense throughout the sentence.
Sentence Fragment	Because I was tired.	Because I was tired, I went to bed early.	A dependent clause cannot stand alone as a sentence.
Run-on Sentence	The sun was shining the birds were singing.	The sun was shining; the birds were singing.	Separate independent clauses with proper punctuation.
Misplaced Modifier	Walking down the street, the tree was beautiful.	Walking down the street, I saw a beautiful tree.	The modifier “walking down the street” should be closer to the subject it modifies.
Pronoun Agreement	Everyone should bring their book.	Everyone should bring his or her book. OR All students should bring their books.	Use “his or her” for singular indefinite pronouns, or revise to a plural form.
Incorrect Word Choice	They’re going to the store.	They are going to the store.	“They’re” is a contraction of “they are,” while “their” indicates possession.
Comma Splice	I went to the store, I bought milk.	I went to the store, and I bought milk.	Use a coordinating conjunction after the comma to join independent clauses.
Dangling Modifier	Having finished the exam, the pizza was ordered.	Having finished the exam, we ordered pizza.	The modifier “having finished the exam” should be closer to the subject it modifies.
Lack of Clarity	It is important.	Education is important.	Be specific about the subject being discussed.

Rhetorical Devices in Declarative Sentences

Declarative sentences can be used to employ various rhetorical devices, such as:

• Anaphora: Repetition of a word or phrase at the beginning of successive clauses. “We shall fight on the beaches, we shall fight on the landing grounds, we shall fight in the fields.”
• Epistrophe: Repetition of a word or phrase at the end of successive clauses. “…that government of the people, by the people, for the people, shall not perish from the earth.”
• Parallelism: Using similar grammatical structures to create a sense of balance and rhythm. “I came, I saw, I conquered.”

Declarative Questions

A declarative question is a statement that is phrased as a question, often indicated by a rising intonation at the end. It is used to seek confirmation or agreement.

Example: You’re coming to the party?

Embedded

Clauses

Declarative sentences can contain embedded clauses, which are clauses nested within the main clause. These clauses can function as nouns, adjectives, or adverbs, adding depth and complexity to the sentence.

Example: I know that she is telling the truth. (Noun clause)

Example: The book that I borrowed from the library is interesting. (Adjective clause)

Example: I will go wherever you go. (Adverb clause)
