Chapter 2- Sentence Structure

1. What is a Subject?

The subject is the part of the sentence that tells us who or what the sentence is about. It is usually a person, animal, or thing that is doing the action.

  • Example: The cat sleeps on the mat.
    • In this sentence, the cat is the subject because the sentence is about the cat.

2. What is a Predicate?

The predicate is the part of the sentence that tells us what the subject is doing or what happens to the subject. It includes the verb (action word) and any words that describe what’s happening.

  • Example: The cat sleeps on the mat.
    • In this sentence, sleeps on the mat is the predicate because it tells what the cat is doing.

3. What is an Object?

An object is a noun (person, place, or thing) that receives the action of the verb. Not all sentences have an object, but when they do, the object is usually the thing or person that the action is done to.

  • Example: She kicked the ball.
    • In this sentence, the ball is the object because it is receiving the action (getting kicked).

4. Examples in Simple Sentences

  • Subject: The dog (who is doing the action)
  • Predicate: barked loudly (what the dog did)
  • Object: the ball (what the dog barked at)

Full sentence: The dog barked loudly at the ball.

Another Example:

  • Subject: Tom (who)
  • Predicate: ate lunch (what Tom did)
  • Object: his sandwich (what Tom ate)

Full sentence: Tom ate his sandwich.


5. Quick Review:

  • Subject = Who or what the sentence is about (e.g., The cat, Tom, She).
  • Predicate = What the subject is doing or what happens to it (e.g., slept, eats, is playing).
  • Object = The person or thing that receives the action of the verb (e.g., the ball, the sandwich).

Understanding subjects, predicates, and objects helps you create clear and complete sentences!

Types of Sentences

Sentences can be different depending on the purpose or meaning. There are four main types of sentences:

  1. Declarative Sentences
  2. Interrogative Sentences
  3. Imperative Sentences
  4. Exclamatory Sentences

Each type of sentence has a different purpose, and they end in different punctuation marks. Let’s take a look at each one!


1. Declarative Sentences

  • What are they? Declarative sentences make a statement or give information. They tell you something.
  • How do they end? They end with a period (.) .
  • Example:
    The sun is shining.
    I love ice cream.

2. Interrogative Sentences

  • What are they? Interrogative sentences ask a question. They want you to give an answer.
  • How do they end? They end with a question mark (?) .
  • Example:
    What is your name?
    Do you like chocolate?

3. Imperative Sentences

  • What are they? Imperative sentences give a command or tell someone to do something. They can also make a request.
  • How do they end? They usually end with a period (.) but can end with an exclamation mark (!) if the command is strong.
  • Example:
    Please pass the salt.
    Sit down!
    Close the door, please.

4. Exclamatory Sentences

  • What are they? Exclamatory sentences show strong feelings like excitement, surprise, or anger.
  • How do they end? They end with an exclamation mark (!) .
  • Example:
    Wow! That was amazing!
    Oh no! I forgot my homework!
    Yay! We won the game!

Quick Review

  • Declarative: Makes a statement or gives information. (Ends with a period.)
    • Example: The dog is sleeping.
  • Interrogative: Asks a question. (Ends with a question mark.)
    • Example: What time is it?
  • Imperative: Gives a command or request. (Ends with a period or exclamation mark.)
    • Example: Please close the window.
  • Exclamatory: Shows strong feeling or excitement. (Ends with an exclamation mark.)
    • Example: Wow, that was fun!

Now you know the four types of sentences and how to use them! 😊

Types of Sentences: Simple, Compound, and Complex

There are three types of sentences based on how they are built: Simple sentences, Compound sentences, and Complex sentences. Let’s look at each one in a simple way!


1. Simple Sentences

  • What are they?
    A simple sentence is a sentence that has one subject and one predicate (action). It expresses a complete thought.
  • How do they look?
    A simple sentence can have just one part of a sentence that gives a complete idea.
  • Examples:
    • I like pizza.
    • The cat sleeps.
    • She reads books every day.

2. Compound Sentences

  • What are they?
    A compound sentence has two simple sentences joined together with a conjunction (like and, but, or, so). These two parts are connected by a conjunction.
  • How do they look?
    A compound sentence has two independent clauses (each part can stand alone as a sentence) joined together.
  • Examples:
    • I want to go to the park, but it is raining.
    • She likes to sing, and he likes to dance.
    • I am hungry, so I will eat lunch.

3. Complex Sentences

  • What are they?
    A complex sentence has one main sentence (independent clause) and one or more extra parts (dependent clauses). The dependent clause cannot stand alone and gives more information about the main sentence.
  • How do they look?
    A complex sentence has one main idea and extra information. The extra information is usually introduced by words like because, if, when, although, and since.
  • Examples:
    • I stayed home because it was raining.
    • If you study hard, you will pass the test.
    • She went to bed early because she was tired.

Quick Review

  • Simple Sentence: One subject + one predicate (complete thought).
    • Example: The dog runs.
  • Compound Sentence: Two simple sentences joined by a conjunction (and, but, so, etc.).
    • Example: I wanted to go to the beach, but it was too cold.
  • Complex Sentence: One main sentence + one or more dependent clauses.
    • Example: I will play outside if it stops raining.
