Chapter 2

In this short reader about sentence run-ons and fragments, we’ve so far discussed the most common sentence-structure errors for students using academic English (EAP), reviewing also the four common structures: simple, compound, complex and compound-complex sentences. In this second and final chapter on the subject, we next focus specifically on identifying sentence fragments, outlining three common ways in which such errors are made and exploring specifically how to avoid such errors.

What is a sentence fragment?  

For a sentence to be grammatical, it must contain a minimum of one independent clause that has a subject and a main verb. This independent clause may then be joined to other independent clauses to form compound sentence structures or to dependent clauses to form complex sentences. Without these initial minimum requirements however, such a construction will simply produce an ungrammatical fragment. We’ve isolated three types of sentence fragment for you below and indicated how to fix them during the proofreading process.


Fragment 1: Using Only Dependent Clauses

As a rule, dependent clauses are introduced with subordinate conjunctions such as ‘because’ and ‘while’ or relative pronouns such as ‘who’ or ‘which’. Such clauses are joined to the beginning or end of other clauses and are sometimes also embedded within the middle of a clause. While dependent clauses are perfectly grammatical once joined to an independent clause, such clause types cannot stand alone as a complete thought or sentence or be joined only to another dependent clause. If students were, therefore, to write either of the following ungrammatical sentences (the ones deleted out in the following examples), they would be creating sentence fragments – sentences that contain only dependent clauses. Corrections to these errors have been provided for your reference in the blue examples below:

Fragment 2: Using Only Phrases

Not only can sentences be considered fragments if they aren’t comprised of at least one independent clause, but so too can phrases be fragments if they are not contained within a complete clause. The deleted sections in the examples below are ungrammatical fragments because they are phrases and not full sentences:

Fragment 3: Having No Subject or Main Verb

As was previously explained, all clauses (except for non-finite clauses) must contain a main verb and a subject at a minimum to be grammatical. As the following examples show however, without either of those two key phrase functions, students will only create ungrammatical fragments that must be later fixed:

Well done on completing this short reader on sentence run-ons and fragments. After completing the Chapter 2 activities, consider next studying another reader about sentence structures to further improve your knowledge.
