When two items are parallel, they share similar components. Parallelism in writing concerns the similarity in structure between ideas and grammatical form. Phrases and clauses that have the same grammatical structure are said to be parallel. If you write single words in a list, you should keep the list as single words. Verb tenses should also remain the same throughout the sentence. If a writer fails to keep parallel form, the sentence(s) or list will feel awkward to the reader; that is, when parallelism is not achieved, it can create a jarring effect for the reader as well a grammatically incorrect structure.
Parallel structure is important when writing a series/list, when presenting ideas as pairs, and when writing verb tenses.
Parallelism in a series or list
In a series or list, all of the items should keep the same grammatical form.
Correct Parallelism: Wizards tend to have the same personality traits: craftiness,
resourcefulness, rebelliousness, and determination.

Faulty Parallelism: Wizards tend to have the same personality traits: craftiness,
resourcefulness, rebelliousness, and they are determined.

Parallelism with ideas presented as pairs
When connecting two independent clauses, an independent clause and phrase, and an independent clause and dependent clause, the grammatical structure should remain the same in both pairs.
You can parallel ideas that come in pairs in four ways:
- Using a coordination conjunction (FANBOYS): For, And, Nor, But, Or, Yet, So
- Using correlative conjunctions: either, not only, but also, etc
- Using a word introducing a comparison: Than
- Using prepositions before and after the FANBOYS
.Parallel ideas connected with a coordinating conjunction (FANBOYS):
Correct Parallelism: Tutors are finding ways to improve their workshops and creating
ways to increase students’ retention of the material.
Faulty Parallelism: Tutors are finding ways to improve their workshops and create ways

to increase students’ retention of the material.
.Parallel ideas connected with correlative conjunction:
When connecting two ideas using either/or, neither/nor, not only/but also, both/and, and whether/or, the second part of the pair should have the same grammatical structure.
Correct Parallelism: The movie I saw was not only too long but also too violent.
Faulty Parallelism: The movie I saw was not only too long but was also extremely violent.
*In this sentence, repeating the to be verb “was” is unnecessary.
.Comparisons connected with than:
When using than, the items compared should be grammatically parallel.

Parallelism Exercise II
Read the following paragraph for parallel grammatical structure. Revise any underlined sections that do not contain proper parallel structure.
Many college courses require students to write essays as part of the class curriculum. An academic essay for a college course should contain a thesis, body, and to conclude. It is important for students to perform some type of pre-writing or to cluster before they start typing on the computer. Pre-writing will usually help students to find and expand new ideas for the paper. After pre-writing, students should type a rough draft using their previous cluster. Students are always nervous in writing the rough draft and started the paper. It is better for students to write to the end of the rough draft than stopping every few sentences to check the grammar. If students do not expand their rough draft, the essay will not only be short but will be also disorganized. Revising the essay for a strong thesis, organization, and proper supporting is the most important part of the writing process. This is what separates the strong writers from the weak writers. The final step in writing a college paper is editing. This is where students will check the paper for grammatical errors, proper punctuating, and spelling errors. A strong writing process will allow students to write a proper college essay.
