Subject and Predicate

Understanding the concepts of subject and predicate is fundamental to mastering English grammar. These two elements are the core components of a sentence, providing the structure and meaning necessary for clear communication. This guide will explore the definitions, types, and examples of subjects and predicates, along with tips for identifying and using them effectively.

What Are Subject and Predicate?

Definition

• Subject: The subject of a sentence is the person, place, thing, or idea that is performing the action or being described.
• Predicate: The predicate of a sentence tells what the subject does or is. It includes the verb and all the words that tell what happened in the sentence.

Examples

• Simple Sentence: The cat (subject) sleeps (predicate).
• Complex Sentence: The cat (subject) sleeps on the couch (predicate).

The Subject

Types of Subjects

1. Simple Subject

The simple subject is the main word or word group that tells whom or what the sentence is about. It is usually a noun or pronoun.

• Examples:
  • The dog barked loudly.
  • She is reading a book.

2. Complete Subject

The complete subject includes the simple subject and all the words that modify it.

• Examples:
  • The brown dog barked loudly.
  • My friend Sarah is reading a book.

3. Compound Subject

A compound subject consists of two or more subjects that are joined by a conjunction and have the same verb.

• Examples:
  • John and Mary went to the market.
  • The cat and the dog are playing.

How to Identify the Subject

1. Find the Verb: Identify the action or state of being in the sentence.
2. Ask "Who" or "What": Ask who or what is performing the action or being described.

• Examples:
  • Sentence: The teacher explains the lesson.
  • Verb: explains
  • Question: Who explains? The teacher (subject).

The Predicate

Types of Predicates

1. Simple Predicate

The simple predicate is the main verb or verb phrase that tells something about the subject.

• Examples:
  • The dog barked.
  • She is reading.

2. Complete Predicate

The complete predicate includes the verb or verb phrase and all the words that give more information about it.

• Examples:
  • The dog barked loudly in the yard.
  • She is reading a fascinating book.

3. Compound Predicate

A compound predicate consists of two or more verbs or verb phrases that are joined by a conjunction and share the same subject.

• Examples:
  • John washed the dishes and cleaned the kitchen.
  • The cat chased the mouse and played with the ball.

How to Identify the Predicate

1. Find the Verb: Identify the action or state of being in the sentence.
2. Determine the Words: Include all the words that complete the verb’s meaning.

• Examples:
  • Sentence: The students finished their homework.
  • Verb: finished
  • Complete Predicate: finished their homework

Sentence Structures

Simple Sentences

A simple sentence contains one independent clause with a subject and a predicate.

  • He runs fast.

Compound Sentences

A compound sentence has two or more independent clauses joined by a conjunction or a semicolon.

• Examples:
  • The cat sleeps, and the dog barks.
  • She studied hard; she passed the exam.

Complex Sentences

A complex sentence contains one independent clause and one or more dependent clauses.

• Examples:
  • The cat sleeps while the dog barks.

Common Mistakes and How to Avoid Them

1. Fragmented Sentences

Ensure every sentence has both a subject and a predicate.

2. Misplaced Modifiers

Place modifiers close to the words they describe to avoid confusion.

Ensure the subject and verb agree in number.

• Incorrect: The dogs runs fast.

By identifying the subject and predicate, you can ensure your sentences convey the intended meaning and avoid common grammatical errors.
