Though it may seem enough to have sentences that are free of grammar or mechanics errors, effective writers know how to combine different types of sentences in order to build rhythm and tension within a paragraph. This tension keeps the reader interested on a subconscious level, and the end result is that the reader will be more invested in reading what you have to say. As a general rule of thumb, use short, simple sentences for emphasis or when you want to clarify an otherwise confusing concept. Use long, complicated sentences to establish connections between ideas and develop the broad context or worldview. What writers should avoid is a paragraph (or essay) in which every sentence is the same general type or the same general length; this monotony is death.
In terms of the four basic types of sentences, there are simple, compound, complex, and compound-complex.
1. A simple sentence (also known as an independent clause) is one complete thought. In other words, there is a subject and predicate. Here is an example: "Photographs surround us."
2. A compound sentence is when the writer uses two complete thoughts (two independent clauses) linked with either a comma and coordinating conjunction (for, and, nor, but, or, yet, so) or a semicolon. Here are two examples: "Photography can be an art form, or a photograph can be a commercial mode of advertising" and "Photography can be an art form; conversely, a photograph can be a commercial mode of advertising." In that second example, "conversely" is a conjunctive adverb. Other examples of conjunctive adverbs include furthermore, however, and nonetheless.
3. A complex sentence is when the writer uses a complete thought combined with a thought made incomplete through the use of a subordinating conjunction (such as while, since, after, although, because, and even though). In other words, a complex sentence has an independent clause paired with a dependent clause. Here are two examples of a complex sentence: "Because photographs surround us, we often take them for granted" and "We often take photographs for granted because they surround us." A writer can either begin the sentence with the dependent clause (in which case a comma would come at the end of that introductory dependent clause) or with the independent clause (in which case there would be no comma).
4. A compound-complex sentence is when the writer has at least two independent clauses and at least one dependent clause. Generally, these are the longest sentences. Here is an example: "When we take and post a selfie to Instagram, we are sharing a vision of both ourselves and how we see the world; this vision can be empowering, but for teenagers these images can also lead to bullying and insecurity."
For this assignment, review your essay's use of syntax, and make sure each paragraph has an effective combination of short, medium, and long sentences. Finally, choose one paragraph to revise and ensure it has an example of a simple, compound, complex, and compound-complex sentence. Post those four sentences to the blog.
