Back in ye olden days (okay, about thirty years ago) elementary school students were taught how to diagram sentences. The theory was that it would be easier to learn the parts of a sentence by seeing the underlying structure. However, as educators moved in the direction of free expression and away from basic mechanics, the diagramming system developed by Reed and Kellogg fell out of fashion.
But, like fresh apple pie made from scratch, sometimes sticking to the basics is best. Diagramming a sentence creates a clear visual that helps you analyze what youre writing. So if you want to brush up on your fundamental sentence skills -- or youre just a grammar nerd -- heres a brief primer on how to diagram sentences.
How to Diagram A SentenceStart with the key elements: subject and verb. Simply put, the subject tells you what the sentence is about; the verb tells you what the subject is doing. If youre feeling rusty about identifying the different parts of a sentence, you may want to do a quick review before you attempt to diagram.
Heres how to draw a diagram for a simple subject and main verb:
Woo-hoo! Now lets get fancy with the adjectives and adverbs that modify the subject, verb, or direct object by placing them under the appropriate word on a slanted line:
- Always write the main sentence line first and then fill in the modifiers.
- Dont use punctuation, but do use capitalization and apostrophes.
- Multiple-word proper nouns (names and titles) and hyphenated words are kept together as a single word.
- When two different adjectives or adverbs modify the same word on the main sentence line, put them in the same left-to-right order as in the original sentence.
I really do not know that anything has ever been more exciting than diagramming sentences. -Gertrude Stein, Lectures in America
You may not feel quite as thrilled as Ms. Stein about the prospect of diagramming sentences, and well let you draw your own conclusions as to how effective the technique is for improving your grammar skills. But if youre interested in reading an in-depth study of sentence diagramming and learning more about its offbeat history, you should definitely check out Sister Bernadettes Barking Dog by Kitty Burns Florey.
CORRECTION: An earlier version of this article described the word 'to' as a linking verb rather than a preposition, and referred to an imperative sentence as declarative.
