Definition of Sentence Diagramming
Sentence diagramming is a method of visually representing the grammatical structure of a sentence. It involves breaking down the sentence into its individual components, such as the subject, verb, object, and modifiers, and arranging them on a diagram to show their relationships to one another.
The most common method, the Reed-Kellogg system, uses a system of horizontal and vertical lines to illustrate the hierarchical relationships between these elements. The main clause is placed on a horizontal line, with the subject and verb identified.
Modifiers, phrases, and clauses are then attached to the main line in various ways to show how they relate to the core components of the sentence.
The primary function of sentence diagramming is to provide a clear and intuitive way to understand the structure of a sentence. By visually mapping out the grammatical relationships, it becomes easier to identify the function of each word or phrase and how it contributes to the overall meaning of the sentence.
This technique is particularly helpful for students learning grammar, as it provides a concrete way to visualize abstract grammatical concepts. It can also be useful for writers who want to improve the clarity and precision of their writing by ensuring that their sentences are grammatically sound and well-structured.
Structural Breakdown of a Sentence Diagram
Understanding the basic components of a sentence diagram is crucial for effective analysis. A typical diagram consists of a horizontal baseline, which represents the main clause of the sentence.
The subject and verb are placed on this line, separated by a vertical line that extends through the baseline. The subject is placed to the left of the verb, and the verb is placed to the right.
Direct objects, indirect objects, and predicate nominatives are placed on the baseline after the verb, each with its own specific placement and markings.
Modifiers, such as adjectives and adverbs, are placed on slanted lines below the words they modify. Prepositional phrases are also attached to the words they modify using slanted lines, with the preposition placed on the line and the object of the preposition placed on a horizontal line below the preposition.
Subordinate clauses are diagrammed separately and then attached to the main clause, showing their relationship to the independent clause.
Here’s a breakdown of the key elements and their representation in a sentence diagram:
- Subject: Placed on the left side of the horizontal baseline.
- Verb: Placed on the right side of the horizontal baseline, separated from the subject by a vertical line.
- Direct Object: Placed on the same baseline as the subject and verb, following the verb, and separated by a vertical line that does not cross the baseline.
- Indirect Object: Placed on a horizontal line below the verb, connected to the verb with a slanted line.
- Predicate Nominative/Adjective: Placed on the same baseline as the subject and verb, following the verb, and separated by a slanted line.
- Adjectives: Placed on slanted lines below the nouns they modify.
- Adverbs: Placed on slanted lines below the verbs, adjectives, or other adverbs they modify.
- Prepositional Phrases: Attached to the words they modify with slanted lines; the preposition is placed on the line, and the object of the preposition is placed on a horizontal line below it.
- Clauses: Diagrammed separately and then attached to the main clause to show their relationship.
Types of Sentences and Diagramming
The complexity of a sentence diagram depends on the type of sentence being analyzed. English grammar recognizes four main types of sentences: simple, compound, complex, and compound-complex.
Each type has its own unique structure and requires a slightly different approach to diagramming.
Simple Sentences
A simple sentence consists of one independent clause, containing a subject and a verb. It expresses a complete thought.
Diagramming a simple sentence is straightforward, as it involves placing the subject and verb on the main baseline and attaching any modifiers accordingly.
For example: “The cat sat on the mat.” In this sentence, “cat” is the subject and “sat” is the verb. “The” is an adjective modifying “cat,” and “on the mat” is a prepositional phrase modifying “sat.”
Compound Sentences
A compound sentence consists of two or more independent clauses joined by a coordinating conjunction (such as *and*, *but*, *or*, *nor*, *for*, *so*, *yet*) or a semicolon. When diagramming a compound sentence, each independent clause is diagrammed separately and then connected with a dotted line representing the conjunction or semicolon.
For example: “The dog barked, and the cat ran away.” In this sentence, “The dog barked” and “the cat ran away” are two independent clauses connected by the coordinating conjunction “and.” Each clause is diagrammed separately, and then the conjunction is placed on a dotted line connecting the two clauses.
Complex Sentences
A complex sentence contains one independent clause and one or more dependent clauses. A dependent clause cannot stand alone as a sentence and is introduced by a subordinating conjunction (such as *because*, *although*, *if*, *when*, *since*, *while*) or a relative pronoun (such as *who*, *whom*, *which*, *that*).
In diagramming a complex sentence, the independent clause is placed on the main baseline, and the dependent clause is attached to it with a dotted line, showing the relationship between the two clauses.
For example: “Because it was raining, I took my umbrella.” In this sentence, “I took my umbrella” is the independent clause, and “because it was raining” is the dependent clause introduced by the subordinating conjunction “because.” The dependent clause is diagrammed separately and then attached to the main clause with a dotted line.
Compound-Complex Sentences
A compound-complex sentence contains two or more independent clauses and one or more dependent clauses. Diagramming a compound-complex sentence involves diagramming each independent clause separately, connecting them with a dotted line representing the coordinating conjunction, and then attaching the dependent clause to the appropriate independent clause with another dotted line.
For example: “Although I was tired, I finished my homework, and then I went to bed.” In this sentence, “I finished my homework” and “then I went to bed” are two independent clauses connected by the coordinating conjunction “and,” and “although I was tired” is a dependent clause introduced by the subordinating conjunction “although.”
Sentence Diagramming Examples
To illustrate the principles of sentence diagramming, let’s look at several examples, covering different types of sentences and grammatical structures. These examples will provide a practical understanding of how to apply the rules and techniques discussed earlier.

Usage Rules for Sentence Diagramming
To effectively use sentence diagramming, it’s essential to follow certain rules and conventions. These guidelines ensure consistency and accuracy in representing the grammatical structure of sentences.
Here are some key usage rules:
- Identify the Main Clause: Always start by identifying the main clause, which contains the subject and verb. This forms the foundation of your diagram.
- Place Subject and Verb Correctly: The subject is placed on the left side of the horizontal baseline, and the verb is placed on the right side, separated by a vertical line.
- Diagram Modifiers Accurately: Adjectives and adverbs should be placed on slanted lines below the words they modify. Ensure that the lines connect to the correct words.
- Handle Prepositional Phrases Correctly: Prepositional phrases are attached to the words they modify with slanted lines. The preposition goes on the slanted line, and the object of the preposition goes on a horizontal line below it.
- Connect Clauses Properly: Independent clauses in compound sentences are diagrammed separately and connected with a dotted line representing the coordinating conjunction. Dependent clauses in complex sentences are attached to the independent clause with a dotted line, showing their relationship.
- Use Correct Line Types: Use solid lines for essential sentence parts (subject, verb, objects) and dotted lines for connections between clauses and phrases.
- Label Parts of Speech: While not always necessary, labeling the parts of speech (e.g., N for noun, V for verb, Adj for adjective) can help clarify the diagram, especially for beginners.
- Maintain Neatness and Clarity: Keep your diagrams neat and easy to read. Use a ruler to draw straight lines, and space the elements appropriately to avoid clutter.
Common Mistakes in Sentence Diagramming
Even with a good understanding of the rules, it’s easy to make mistakes when diagramming sentences. Here are some common errors to watch out for:
- Misidentifying the Subject or Verb: Confusing the subject or verb can throw off the entire diagram. Ensure you correctly identify the main actor and action in the sentence.
- Incorrect Placement of Modifiers: Placing modifiers under the wrong words can distort the meaning of the sentence. Double-check that each modifier is connected to the word it describes.
- Improper Handling of Prepositional Phrases: Forgetting to include the preposition or misplacing the object of the preposition are common errors. Ensure the preposition is on the slanted line and the object is on the horizontal line below it.
- Incorrect Clause Connections: Failing to connect clauses properly with dotted lines or misidentifying the type of clause can lead to an inaccurate diagram.
- Overcomplicating Simple Sentences: Trying to apply complex rules to simple sentences can lead to unnecessary complications. Keep simple sentences straightforward.
- Ignoring Compound Elements: Failing to recognize and diagram compound subjects, verbs, or objects can result in an incomplete diagram.
