Understanding Sentence Structure

What is a Sentence? 

A sentence is a group of words that expresses a complete thought. It is made up of a subject and a predicate, and it usually ends with a punctuation mark, such as a period, question mark, or exclamation point. 

What is subject?
The subject of a sentence is the person, place, thing, or idea that the sentence is about.

What is Predicate?
The predicate is what the subject is doing or what is being said about the subject.

Let’s look at some examples to get an understanding of sentence structure.

  • The cat is sleeping. (Subject: cat; Predicate: is sleeping.) 
  • I like pizza. (Subject: I; Predicate: like pizza.) 
  • The sun is shining brightly. (Subject: sun; Predicate: is shining brightly.) 

Sentence Structure

English sentences have a basic structure, which includes a subject and a predicate. However, the structure of a sentence can vary depending on the type of sentence being used. Here are the four types of sentences: 

  1. Declarative sentences: These sentences make a statement or express an opinion. They end with a period. 
    • Example: The sky is blue. 
  2. Interrogative sentences: These sentences ask a question. They end with a question mark. 
    • Example: Do you like ice cream? 
  3. Imperative sentences: These sentences give a command or make a request. They end with a period. 
    • Example: Please pass the salt. 
  4. Exclamatory sentences: These sentences express strong emotion or excitement. They end with an exclamation mark. 
    • Example: What a beautiful day it is! 

Now that you know the four types of sentences, let’s look at some examples of each type: 

  • Declarative: I love playing basketball. 
  • Interrogative: Where did you go on vacation? 
  • Imperative: Clean up your room, please. 
  • Exclamatory: I can’t believe I won the game! 

Sentence Types

There are different types of sentences in English, and they can be classified based on their structure or function. Here are some common types of sentences based on their structure: 

  1. Simple sentence: A simple sentence contains one independent clause (a group of words that can stand alone as a complete sentence) and expresses a complete thought.
    • For example: 
      • She sings a song. 
      • He eats breakfast every morning. 
  2. Compound sentence: A compound sentence contains two or more independent clauses joined together by a coordinating conjunction (and, but, or, so, for, yet, nor).
    • For example: 
      • She sings a song, and he plays the guitar. 
      • I wanted to go to the park, but it started raining. 
  3. Complex sentence: A complex sentence contains one independent clause and one or more dependent clauses (a group of words that cannot stand alone as a complete sentence) joined together by a subordinating conjunction (although, because, since, while, when, after, before).
    • For example: 
      • Although she was tired, she went to the party. 
      • Because he had to work, he couldn’t come to the concert. 
  4. Compound-complex sentence: A compound-complex sentence contains two or more independent clauses and one or more dependent clauses, joined together with coordinating and subordinating conjunctions.
    • For example: 
      • She sings a song, and he plays the guitar, although he is not very good at it. 
      • I wanted to go to the park, but it started raining, so I stayed home and watched a movie. 

In addition to understanding sentence structures, it’s important to understand the different parts of a sentence, including clauses, phrases, subjects, and objects. 

Clause

A clause is a group of words that contains a subject and a predicate. There are two main types of clauses: independent and dependent. An independent clause can stand alone as a complete sentence, while a dependent clause cannot. A dependent clause typically begins with a subordinating conjunction, such as “although,” “because,” “since,” “when,” or “while.” 

Here are some examples of independent and dependent clauses: 

Independent clause: 

  • The dog barks. 

Dependent clause: 

  • Although the dog barks. 

Phrase

A phrase is a group of words that functions as a single unit within a sentence, but does not contain both a subject and a predicate. Phrases can function as nouns, adjectives, or adverbs within a sentence. 

Here are some examples of phrases: 

Noun phrase: 

  • The dog barking at the mailman. 

Adjective phrase: 

  • The book on the shelf. 

Adverb phrase: 

  • He ran down the street as fast as he could. 

Subject

The subject of a sentence is the person, thing, or idea that the sentence is about. The subject usually comes before the predicate in a sentence. 

Here are some examples of subjects: 

  • The dog barks. 
  • She sings a song. 

Object

The object of a sentence is the person, thing, or idea that receives the action of the verb in the predicate. The object usually comes after the verb in a sentence. 

Here are some examples of objects: 

  • The dog chases the ball. 
  • She gave him a present. 

By understanding clauses, phrases, subjects, and objects, you can analyze and understand sentences more deeply, and use this understanding to improve your writing and communication skills.
