Reed-Kellogg Diagrams

Understanding Reed-Kellogg Diagrams

Reed-Kellogg diagrams are a graphical method for representing the grammatical structure of a sentence. Developed by Alonzo Reed and Earl Kellog in the late 19th century, they break down sentences into their constituent parts, showing the relationships between words. This visual approach aids in understanding syntax and sentence construction.

Key Concepts

The core of a Reed-Kellogg diagram involves a baseline representing the main subject and verb. Modifiers, objects, and other sentence elements are placed on slanted or horizontal lines connected to the appropriate words on the baseline.

• Subject and verb form the main horizontal line.
• Modifiers (adjectives, adverbs) are placed on slanted lines below the word they modify.
• Direct objects and predicate nominatives/adjectives are separated by a vertical line on the same horizontal level as the verb.

Deep Dive into Diagramming

Diagramming compound subjects, verbs, and clauses requires specific conventions. Compound elements are shown with parallel lines, while subordinate clauses are diagrammed on separate lines, connected to the main clause.

Example: The quick brown fox jumps.

• Baseline: fox | jumps
• Modifiers of fox: The, quick, brown (slanted lines below ‘fox’)

Applications and Benefits

Reed-Kellogg diagrams are invaluable for students learning grammar, writers seeking clarity, and linguists studying sentence structure. They help identify grammatical errors and improve writing precision.

Challenges and Misconceptions

Some find the initial learning curve steep. A common misconception is that diagrams are overly simplistic; however, they can represent highly complex sentences accurately with practice.
