How Do You Identify The Subject In A Sentence

Identifying the Subject in a Sentence: A Comprehensive Guide

Identifying the subject of a sentence is a fundamental skill in grammar. Understanding the subject—the noun or pronoun performing the action or being described—is crucial for sentence structure, comprehension, and effective writing. This comprehensive guide will equip you with the knowledge and tools to confidently identify subjects in even the most complex sentences. We'll cover basic sentence structures, complex sentence types, and common pitfalls, ensuring you master this essential grammatical concept.

Introduction: What is a Subject?

The subject of a sentence is the person, place, thing, or idea that performs the action of the verb or is being described by the verb. Think of it as the "who" or "what" the sentence is about. In the simple sentence, "The cat sat on the mat," the subject is "the cat" because it's the one performing the action of sitting. Simple enough, right? But sentence structure can get significantly more complex, so let's delve into the details.

Identifying Subjects in Simple Sentences

Simple sentences contain one independent clause – a clause that can stand alone as a complete thought. These sentences typically follow a straightforward Subject-Verb-Object (SVO) structure.

• Subject (S): The actor or topic of the sentence.
• Verb (V): The action or state of being.
• Object (O): The receiver of the action (optional; not all sentences have objects).

Examples:

• Birds fly. (Subject: Birds; Verb: fly)
• The dog barked loudly. (Subject: The dog; Verb: barked)
• She sings beautifully. (Subject: She; Verb: sings)
• My car needs a wash. (Subject: My car; Verb: needs)

Finding the Subject: Start by identifying the verb. Then ask yourself, "Who or what is performing this action?" The answer is your subject.

Identifying Subjects in Compound Sentences

Compound sentences contain two or more independent clauses, usually joined by coordinating conjunctions (e.g., and, but, or, nor, for, so, yet). Each independent clause will have its own subject and verb.

Examples:

• The sun shone brightly, and the birds sang merrily. (Subject 1: The sun; Subject 2: The birds)
• My brother loves to cook, but he rarely cleans up. (Subject 1: My brother; Subject 2: he)
• She went to the store, and I stayed home. (Subject 1: She; Subject 2: I)

Finding the Subject: Identify each independent clause separately. Apply the same method as with simple sentences: find the verb and ask "Who or what?" to determine the subject.

Identifying Subjects in Complex Sentences

Complex sentences contain one independent clause and one or more dependent clauses. Dependent clauses cannot stand alone as complete sentences; they rely on the independent clause for meaning. These clauses often begin with subordinating conjunctions (e.g., because, although, since, if, when).

Examples:

• The house, which is painted blue, is my home. (Main clause subject: The house; Dependent clause subject: which)
• Although it was raining, we went for a walk. (Main clause subject: we; Dependent clause subject: it)
• Because the test was difficult, many students failed. (Main clause subject: many students; Dependent clause subject: the test)

Finding the Subject: Focus on the independent clause. Ignore the dependent clause initially to identify the main subject and verb. Then, analyze each dependent clause separately to find its subject.

Dealing with Inverted Sentence Structure

In some sentences, the subject comes after the verb, creating an inverted sentence structure. This is common in questions and sentences beginning with certain adverbs or phrases.

Examples:

• Is the book on the table? (Subject: the book; Verb: is)
• There are many cars in the parking lot. (Subject: many cars; Verb: are; Note: "There" is an expletive, not the subject.)
• Never have I seen such beauty. (Subject: I; Verb: have seen)

Finding the Subject: Rearrange the sentence into a more typical subject-verb order if needed. Ask "Who or what is performing the action?" or "Who or what is being described?" to find the subject. Be mindful of expletives like "there" and "here," which are not subjects.

Identifying Subjects with Compound Subjects

A compound subject consists of two or more nouns or pronouns joined by a coordinating conjunction (and, or, nor) or a comma.

Examples:

• My sister and I went to the movies. (Compound subject: My sister and I)
• Tom or Mary will win the prize. (Compound subject: Tom or Mary)
• Neither the cat nor the dog wanted to go outside. (Compound subject: Neither the cat nor the dog)

Finding the Subject: The entire compound subject acts as a single unit performing the verb's action.

Identifying Subjects with Linking Verbs

Linking verbs (e.g., is, are, was, were, seems, becomes) don't show action; they connect the subject to a subject complement (a noun, pronoun, or adjective that renames or describes the subject). The subject complement is not the subject.

Examples:

• She is a doctor. (Subject: She; Linking verb: is; Subject complement: a doctor)
• The flowers are beautiful. (Subject: The flowers; Linking verb: are; Subject complement: beautiful)
• He became a famous writer. (Subject: He; Linking verb: became; Subject complement: a famous writer)

Finding the Subject: The subject will be the noun or pronoun before the linking verb.

Identifying Subjects in Sentences with Intervening Phrases or Clauses

Sentences often contain phrases or clauses that interrupt the flow between the subject and verb. These phrases don't affect the identification of the subject.

Examples:

• The book, which I borrowed from the library, is overdue. (Subject: The book; Intervening clause: which I borrowed from the library)
• My friend, along with her family, travelled to Europe. (Subject: My friend; Intervening phrase: along with her family)

Finding the Subject: Ignore the intervening phrases or clauses and focus on the main subject-verb relationship.

Common Mistakes in Identifying Subjects

• Confusing the subject with the object: Remember, the subject performs the action; the object receives it.
• Misidentifying expletives as subjects: Words like "there," "here," and "it" (when used as anticipatory subjects) are not subjects themselves.
• Overlooking compound subjects: Remember to consider the entire compound subject as a single unit.
• Ignoring the true subject in inverted sentences: Be sure to identify the true subject even when it’s positioned after the verb.

Advanced Techniques for Identifying Subjects

As you progress in your understanding of grammar, you'll encounter more nuanced sentence structures. Here are some advanced techniques:

• Diagraming sentences: Sentence diagramming provides a visual representation of sentence structure, which can be helpful in identifying subjects and their relationships to other sentence elements.
• Using parsing techniques: Parsing involves breaking down a sentence into its constituent parts, analyzing the grammatical function of each word or phrase.
• Analyzing different sentence patterns: Familiarize yourself with various sentence patterns beyond the basic SVO structure.

Frequently Asked Questions (FAQ)

• Q: What if the sentence doesn't have a clear verb? A: Look for a linking verb or a verb implied in the context. For example, in the sentence "The situation dire," the implied verb is "is."
• Q: Can a subject be more than one word? A: Yes, as seen with compound subjects and phrases acting as subjects.
• Q: Can a subject be a clause? A: Yes, a noun clause can act as the subject of a sentence. For example, "That he won the lottery is amazing." ("That he won the lottery" is the subject).
• Q: How do I identify the subject in a command? A: In a command, the subject is usually implied as "you." For example, "Close the door" – the implied subject is "you."
