Lesson 1

One aspect of English grammar that students often look for assistance with is in recognising, deconstructing and recreating a variety of sentence structures. It’s important for a university student to have a good grasp of this topic because knowing a compound sentence from a complex sentence or a sentence fragment from a run-on sentence will allow for much more careful editing and more dynamic writing. When combined, both of these aspects should therefore lead to more coherent writing that receives a higher overall grade.


1. Careful Editing

While some grammatical inconsistencies can be more or less ignored by a reader as they don’t impede meaning, this isn’t the case for sentence-structure errors. Consider the following example:

Sentence Structures 1.1 Careful Editing

Clearly, when sentence structures go wrong as in the above example, such text becomes extremely difficult to understand. What we were trying to say in the previous example was that “a piece of text can be difficult to understand if the sentences which that text contains are not correctly formed or punctuated. If key aspects of a sentence are missing such as that sentence’s subject or main verb, or if the sentences are joined without proper use of conjunctions or correct punctuation then the reader will likely become very confused.”

Many common sentence-structure errors that greatly impede meaning such as sentence fragments, comma splices and sentence run-ons can all be avoided with a confident knowledge of sentence structures. A student that has this knowledge, therefore, should be able to submit a higher quality of edited writing.


2. Dynamic Writing

Another motivation for learning to recognise and utilise a variety of sentence structures is to make your writing more varied and dynamic. Consider the following two examples: 

Sentence Structures 1.2 Dynamic Writing
Sentence Structures 1.3 Dynamic Writing

The first example contains nine very short sentences, most of which are simple sentences composed of only one subject and one verb. Example 1 is short and snappy, but feels somewhat disjointed and repetitive. The second example, however, contains only four sentences which have been conjoined in a number of different ways. This text uses a variety of sentence structures correctly, and although the meaning between these two texts is very much the same, the second text is clearly more dynamic and varied – and therefore easier and more pleasurable to read. Your writing can be more dynamic and varied too, provided you understand and are able to use the variety of sentence structures which are on offer.
