Understanding how to identify subject and predicate in a sentence is essential for improving grammar, writing, and reading comprehension. The subject and predicate are the two core components of every complete sentence. Recognizing these parts helps break down the structure of a sentence and makes it easier to analyze meaning, construct well-formed sentences, and detect grammatical issues. Whether you’re learning English as a second language or polishing your writing skills, knowing how to find the subject and predicate will significantly enhance your command of language.
What Are Subject and Predicate?
Basic Definitions
The subject of a sentence is the person, place, thing, or idea that the sentence is about. It tells us who or what is performing the action or being described.
The predicate, on the other hand, contains the verb and provides information about what the subject is doing or what is happening to the subject. Together, the subject and predicate form a complete thought.
Examples for Clarity
- Johnruns every morning.
- The dogbarked loudly at the mailman.
In the examples above, ‘John’ and ‘The dog’ are the subjects, while ‘runs every morning’ and ‘barked loudly at the mailman’ are the predicates.
How to Identify the Subject
Step 1: Find the Verb First
Before identifying the subject, it often helps to locate the verb or action word in the sentence. This allows you to ask the question: Who or what is performing this action?
Step 2: Ask ‘Who or What’ Before the Verb
Once you identify the verb, ask who or what is doing the action. The answer to that question is the subject.
Example Analysis
Sentence: The children played soccer after school.
- Verb: played
- Who played? → The children
Therefore, ‘The children’ is the subject of the sentence.
Subjects Can Be Simple or Complete
Thesimple subjectis the main noun or pronoun, while thecomplete subjectincludes all the words that describe or modify it.
- Simple subject: cat
- Complete subject: The black and white cat
How to Identify the Predicate
Step 1: Locate the Verb or Verb Phrase
The predicate always starts with the verb. It can be a single verb or a verb phrase that includes helping verbs or modifiers.
Step 2: Include Everything After the Subject
The complete predicate includes the verb and all the words that follow it, describing the action or providing more information about the subject.
Example Analysis
Sentence: The tall man in a blue suit answered the phone.
- Verb: answered
- Predicate: answered the phone
Here, ‘answered the phone’ is the complete predicate, and ‘The tall man in a blue suit’ is the complete subject.
Tips for Spotting Subjects and Predicates
- In questions, the subject may come after the verb. Example: Did she call you? (Subject: she)
- In commands, the subject is often implied. Example: Close the door. (Subject: you)
- Be cautious with sentences starting with there or here. These are usually not the subjects. Example: There is a book on the table. (Subject: book)
Compound Subjects and Predicates
Some sentences have more than one subject or predicate, known as compound structures.
- Compound subject: Sarah and Tom went to the store.
- Compound predicate: The baby laughed and clapped her hands.
Subject and Predicate in Complex Sentences
Multiple Clauses
Complex or compound sentences may contain multiple independent or dependent clauses. Each clause has its own subject and predicate.
Example: Although she was tired,Mariacontinued working.
- Dependent clause: Although she was tired → Subject: she; Predicate: was tired
- Main clause: Maria continued working → Subject: Maria; Predicate: continued working
Understanding Clauses Improves Clarity
Breaking down complex sentences into clauses and then identifying the subject and predicate in each part is an effective way to master sentence structure. This method is useful for grammar tests, academic writing, and editing.
Common Mistakes When Identifying Subject and Predicate
- Confusing modifiers with the subject: Don’t mistake descriptive words for the core subject.
- Missing implied subjects in commands: Remember that in imperative sentences, the subject is usually ‘you.’
- Overlooking compound subjects or predicates: Identify each part and avoid mistaking them for a single element.
Practice Examples
Sentence 1
The little boy with the red hat smiled brightly.
- Subject: The little boy with the red hat
- Predicate: smiled brightly
Sentence 2
Anna and her brother cleaned the garage and washed the car.
- Compound Subject: Anna and her brother
- Compound Predicate: cleaned the garage and washed the car
Sentence 3
Where are your shoes?
- Subject: your shoes
- Predicate: are
Why Identifying Subject and Predicate Matters
Mastering the subject and predicate helps in writing grammatically correct sentences, avoiding fragments or run-ons, and improving clarity. It also builds a solid foundation for learning other aspects of grammar, such as subject-verb agreement, tense consistency, and clause construction.
Learning how to identify the subject and predicate in a sentence is a fundamental skill in grammar. By understanding the structure of simple and complex sentences, you gain control over your writing and communication. Always begin by spotting the verb and asking who or what performs the action to find the subject. Then, include all the information related to the action to determine the predicate. With regular practice and attention to sentence patterns, identifying these elements becomes second nature and greatly enhances both written and spoken language skills.
