Parallel Structure by Jeff Young

Background
Some writers like to constantly vary the form or pattern of a sentence to make it seem more interesting. But this technique can make the writing clunky, awkward and confusing. The principle of parallel structure requires that the elements of a sentence that are alike in meaning or function be alike in construction. Parallelism creates rhythm and balance and enables the writer to present ideas clearly, concisely and smoothly. It makes reading easier to understand, pleasing to the ear and more persuasive.

Usage

Non-parallel: Formerly, science was taught by the textbook method, while now the laboratory method is used.

Parallel: Formerly, science was taught by the textbook method; now it is taught by the laboratory method.

In the second example, both clauses use the same pattern (“taught by”). The writing is decisive and easier to read.

More examples of parallel vs. non-parallel structure:

Non-parallel: “Biff’s application was correctly completed, on time, and it was neat.” Parallel: “Biff’s application was correctly completed, on time, and neat.”

Non-parallel: “John Belushi is remembered for his physical style of comedy, his blues singing, and for behavior that was self-destructive.” Parallel: “John Belushi is remembered for his physical style of comedy, his blues singing, and his self-destructive behavior.”

Tip

Parallelism also applies to lists — something to keep in mind when writing a memo or PowerPoint presentation. For example:
MSLGROUP Americas has three distinct strengths:

+ We are stewards of ROI
+ Trusted advice
+ We deliver insights-guided thinking

By using parallel structure and changing the second bullet to “We offer trusted advice,” your point will come across more clearly.
