What grammatical components you should be able to identify before diagramming?īefore we get down to actually diagramming sentences, let’s review the technical elements that sentences are composed of: parts of speech and sentence constituents. The most commonly used method is known as the Reed–Kellogg system, which is what we discuss here. Sentence diagramming uses a fixed set of rules and a standardized “code” of line types (e.g., diagonal lines, dotted lines, etc.) so that anyone who knows how to diagram a sentence can read other people’s sentence diagrams. Knowing how to identify what roles each word plays in a sentence based on their function and placement is an excellent practice for both improving your English writing and learning how to write better sentences. We’ll explain everything you need to know below so that you, too, can understand sentence diagrams.
