- A sentence needs a subject and a verb to express a complete thought.
- Sentences can be simple, compound, complex, or compound-complex.
- Simple sentences have one independent clause.
- Compound sentences join two independent clauses.
- Complex sentences have one independent and one dependent clause.
- Compound-complex sentences combine one independent and multiple dependent clauses.
A sentence is a group of words that expresses a complete thought. When we speak or write, we use sentences to share information, ideas, and feelings. There are some basic rules for constructing sentences in English. Understanding these rules can help you write and speak correctly. This article will explain what makes a complete sentence. It will cover the different types of sentences and provide examples. With this knowledge, you will be able to confidently compose clear and complete sentences.
The goal of this article is to comprehensively break down sentence structure and mechanics. We will evaluate the essential elements that every sentence needs. You will also learn how to identify and properly use the four main sentence types. Grasping these fundamental concepts will bolster your language skills. It will enable you to articulate your thoughts accurately through well-formed sentences. Let’s dive in to unlock the components and varieties of sentences!
Knowing the makeup and function of proper sentences is a valuable skill. It allows you to clearly convey ideas and information in speech and writing. With a solid handle on sentence composition, your communication will become more lucid and precise. This article provides in-depth knowledge to advance your sentence construction abilities.
What are the Basic Parts of a Sentence??
A complete sentence needs two main components:
The subject indicates who or what the sentence is about. It can be one word or a group of words. The subject is commonly a noun or pronoun.
- The cat
- The tall girl with red hair
The predicate describes the subject or adds more information about it. It always contains a verb.
- flows slowly down the volcano.
- jumped up on the table.
- ran to class because she was late.
- studies math and science at school.
So in a basic sentence, the subject names who or what the sentence is about, while the predicate reveals something about the subject.
Here is a simple sentence with the subject and predicate labeled:
The dog (subject) barked loudly (predicate).
What Makes a Complete Sentence??
To be complete, a sentence must:
- Have a subject and predicate
- Express a complete thought
If a sentence is missing a subject or predicate, it will be a fragment instead of a full sentence.
Sentence fragment example:
Barking loudly last night.
This has a predicate (barking loudly) but no subject. So it is incomplete and lacks a complete thought.
Let’s add a subject to make it a complete sentence:
The dog was barking loudly last night.
Now this sentence has all the necessary parts to be complete.
A complete sentence also needs to share a thought, ask a question, give a command, express an exclamation, or convey a statement. Just having a subject and predicate is not enough to form a full sentence.
Not a complete sentence: The cat on the mat.
While this has a subject (cat) and predicate (on the mat), it does not express a complete thought. We need more information:
Complete sentence: The cat sat on the mat.
This example now fully communicates the thought and forms a meaningful, complete sentence.

What are the 4 Types of Sentences??
There are four main types of sentences in English:
1. Simple Sentences
Simple sentences contain one independent clause. An independent clause is a group of words with a subject and predicate that expresses a complete thought.
The boy ran.
This sentence has one subject (boy) and one predicate (ran). It forms one independent clause that stands alone as a full sentence.
Other qualities of simple sentences:
- Contain a single thought or idea
- Do not have any subordinate clauses
- Use coordinating conjunctions like “and”, “but”, and “so” to join parts
Simple sentence example:
The rain poured down and the wind howled loudly all night long.
2. Compound Sentences
Compound sentences join two independent clauses together with a coordinating conjunction. The two clauses can stand on their own as complete simple sentences.
Common coordinating conjunctions:
Compound sentence example:
The girl scored a goal, but the team did not win.
This contains two independent clauses – “The girl scored a goal” and “the team did not win” – joined by the coordinating conjunction “but”.
Other qualities of compound sentences:
- Joins two complete simple sentences
- Requires a comma before the coordinating conjunction
- Expresses two related thoughts
3. Complex Sentences
Complex sentences contain one independent and one dependent clause. The independent clause stands alone, while the dependent clause cannot.
A dependent clause has a subject and verb but does not express a complete thought. Common dependent markers are:
Complex sentence example:
The class held a bake sale after they finished their final exams.
Independent clause: The class held a bake sale Dependent clause: after they finished their final exams
The dependent clause gives context for the independent clause.
- Joins an independent and dependent clause
- Commas typically separate the clauses
- Dependent clause relies on the independent clause to complete its meaning
4. Compound-Complex Sentences
Compound-complex sentences combine compound and complex structures. They have multiple independent clauses joined by coordinating conjunctions, as well as at least one dependent clause.
The students planned a fundraiser, so they could buy new computers, but first they needed to decide on a date.
- 2 independent clauses joined by the coordinating conjunction “so”
- 1 dependent clause “but first they needed to decide on a date”
- Most sophisticated sentence structure
- Joins multiple independent and dependent clauses
- Separate independent clauses with commas and coordinating conjunctions
- Can show complex relationships between ideas
5 Common Sentence Structure Questions
Now that you know the basic parts and types of sentences, let’s go over some frequently asked questions about sentence structure:
How do you start a sentence??
There are many ways to begin a sentence. You can start with the:
- Subject – The boy ran down the street.
- Predicate – Ran down the street, the boy did.
- Transition word – Consequently, he arrived late for dinner.
- Prepositional phrase – In a hurry, he sprinted home.
- Dependent clause – Before the clock struck midnight, Cinderella fled the ball.
Avoid overusing the same sentence structure repeatedly. Varying your openings keeps writing engaging.
How do you end a sentence??
Proper punctuation is needed to finish a sentence correctly. Here are some common ways sentences end:
- Period – I went to the store.
- Question mark – Where did you go?
- Exclamation point – Watch out!
- Comma – I went to the store, but it was closed.
Do not over-rely on short, choppy sentences. Use different sentence lengths and structures to conclude sentences.
What makes a good sentence structure?
An effective sentence structure:
- Has a clear subject and predicate
- Expresses a complete thought
- Is direct, uncomplicated, and easy to read
- Uses transition words to connect ideas and flow smoothly
- Employs a mix of simple, compound, complex, and compound-complex sentences
- Is concise while still providing important details
- Engages the reader with descriptive language
Well-structured sentences allow you to communicate ideas clearly.
How can you vary sentence structure?
Some ways to diversify sentence structure include:
- Beginning sentences with different parts of speech (noun, verb, prepositional phrase, etc.)
- Using simple, compound, complex, and compound-complex sentence forms
- Alternating between short and long sentences
- Changing up punctuation (. ! ? ,)
- Embellishing sentences with descriptive words and literary devices like alliteration, repetition, and imagery
Avoid letting sentences become too repetitive in pattern, length, or style.
When do you use different sentence types?
Think about what you want to express to decide which structure to use:
- Simple – Make short, definitive statements
- Compound – Show contrast, link two related ideas
- Complex – Subordinate less important details to the main idea
- Compound-complex – Show interconnected, complex relationships

Understanding sentence composition is key to expressing your thoughts in speech and writing. A complete sentence requires a subject and a predicate to form an independent clause sharing a complete idea. Sentences come in four types – simple, compound, complex, and compound-complex. Simple sentences have one independent clause, while compound sentences join two independent clauses. Complex sentences combine one independent and one dependent clause. Compound-complex sentences interweave multiple independent and dependent clauses. Mastering varied sentence structures creates more engaging communication. Use this knowledge to build excellent sentences that convey your message clearly and effectively
