Masterful authors learn to vary the structure of their sentences to create a sense of rhythm and it helps keep readers engaged.

How we arrange the different elements in a sentence is referred to as the sentence structure. Two sentences can say the same exact thing but be arranged in a way that it is not recognizable, unless you were looking for it. There is a number of reasons that authors mix up their sentence structure, in most cases, it centers around the fact that you are repeating a subject or making repeated statements. If we present that the same way over and over, it could lull your readers to sleep.

There are three common situations where an author will decide they need a change in sentence structure. The easiest one to spot is a need to vary the use of a subject or the need to mix up your word choice. I find that teachers use the word “education” way too much in their writing. This is something I note in my own writing. Another telltale sign that your sentence needs some smoothing is sentence length. Try not overuse lengthy or short sentences, they will either seem bloated or too simple. It is a good practice to vary your sentence length when writing. The toughest pattern to spot in your writing, because it takes time to analyze, is the repeated use of the same sentence type. Are you repeatedly using simple, compound, or complex sentences? These worksheets will help you learn to diagnose your sentence writing and the work of others. These worksheets will have you breaking apart sentences and diagnosing the composition that is exhibited in each. We will also examine the differences between sentences and fragments. The worksheets will also explore how to form the building blocks of well written thoughts. Break these down to make the most of your experience with this form of language expression.

Clauses and Structure

There are four kinds of sentence structures: simple, compound, complex, and compound complex. They are all created by using only two kinds of clauses: independent clauses and subordinate (dependent) clauses.

Creating Compound Sentences

A compound sentence contains two or more related simple sentences joined by a conjunction. A conjunction is a word like and, as, for, yet or but that connects words or groups of words. A comma is used before a conjunction.
