Parallel structure and concision

Parallel structure uses matching grammatical forms in a series, and concise writing cuts words that do no work.

Two keys to polished prose

Strong writers make sentences that are balanced and efficient. Two skills make this possible:

  1. Parallel structure: matching grammatical forms so ideas line up clearly.
  2. Concision: removing unnecessary words so every word earns its place.

Both improve clarity, rhythm and persuasiveness.

Part 1: Parallel structure

Parallel structure (parallelism) means using the same grammatical form for similar elements: words, phrases or clauses.

In a series

✗ She likes hiking, to swim and riding bikes.
✓ She likes hiking, swimming and biking.
✓ She likes to hike, to swim and to bike.

✗ The coach told us to stretch, that we should hydrate and get enough sleep.
✓ The coach told us to stretch, to hydrate and to sleep enough.

With coordinating conjunctions

Items joined by and, but, or should match.

✗ The job requires creativity and being organized.
✓ The job requires creativity and organization.

With correlative conjunctions

Correlative conjunctions come in pairs: either…or, neither…nor, not only…but also, both…and, whether…or. The elements following each part must be parallel.

✗ She is not only talented but also works hard.
✓ She is not only talented but also hardworking.
✓ She not only sings well but also works hard.

In comparisons

✗ Reading a book is better than to watch the movie.
✓ Reading a book is better than watching the movie.

In lists and headings

Bulleted lists and headings should be parallel:
✗ Goals: Improve grades / Making new friends / To join a club
✓ Goals: Improve grades / Make new friends / Join a club

Faulty parallelism

Faulty parallelism is the error of mixing forms. Test by isolating each item with the sentence’s shared start:

The plan aims to reduce costs, improving safety and more efficiency.
– aims to reduce costs ✓
– aims to improving safety ✗
– aims to more efficiency ✗
Fix: The plan aims to reduce costs, improve safety and increase efficiency.

The power of parallelism

Parallelism creates rhythm and emphasis, which makes it a favourite device in speeches:

  • “Government of the people, by the people, for the people.” (Abraham Lincoln)
  • “I came, I saw, I conquered.” (attributed to Julius Caesar)

Part 2: Concision

Concision means saying what you mean in as few words as necessary, without losing meaning or voice. Concise writing respects the reader’s time and makes arguments sharper.

1. Cut redundancy

Redundancy repeats an idea unnecessarily.

Redundant Concise
past history history
end result result
free gift gift
each and every each
completely finished finished
advance planning planning
repeat again repeat
true facts facts

2. Replace wordy phrases

Wordy Concise
due to the fact that because
in order to to
at this point in time now
in the event that if
has the ability to can
in spite of the fact that although
for the purpose of to, for
a large number of many

3. Avoid nominalizations

A nominalization turns an action into a noun, adding words and hiding who acts.

✗ The committee made a decision to conduct an investigation.
✓ The committee decided to investigate.

4. Limit expletive constructions

An expletive construction (There is/are, It is) delays the real subject.

✗ There are many students who volunteer.
✓ Many students volunteer.

✗ It is important to note that the results varied.
✓ The results varied.

5. Prefer active voice (usually)

✗ The decision was made by the council.
✓ The council made the decision.

6. Cut empty intensifiers and hedges

Very, really, quite, basically, actually, kind of, sort of often add little.

✗ The results were really very surprising.
✓ The results were astonishing.

7. Eliminate throat-clearing

✗ In this essay, I am going to discuss the ways in which…
✓ Begin directly with your point.

Concision is not just shortness

Do not cut details that add meaning, evidence or voice. The goal is no wasted words, not the fewest possible words.

Worked example

Original (41 words): In my opinion, I think that it is really important for schools to make a decision to provide students with the opportunity to learn about financial literacy, budgeting skills and how to manage money due to the fact that it helps.

Revised (19 words): Schools should teach financial literacy, including budgeting and money management, because these skills help students make responsible decisions.

Fixes: removed redundancy (In my opinion, I think), nominalization (make a decision), wordy phrases (due to the fact that), intensifier (really), and repaired parallelism (financial literacy, budgeting, money management).

Try it yourself

  1. Fix the parallelism: The volunteers cleaned the park, were planting trees and painted benches.
  2. Fix: She wants either to study medicine or law.
  3. Make concise: At this point in time, there are a large number of people who have the ability to work from home.
  4. Undo the nominalization: The teacher gave an explanation of the assignment.

Answers: 1. The volunteers cleaned the park, planted trees and painted benches. 2. She wants to study either medicine or law. 3. Many people can now work from home. 4. The teacher explained the assignment.

Study tip

Set a word-cutting goal when revising: try to remove 10 percent of your draft’s words without losing any ideas. You will be surprised how much stronger it reads.

Quick recap

  • Parallel structure matches grammatical forms in series, pairs and comparisons.
  • Correlative conjunctions require parallel elements after each part.
  • Concision eliminates redundancy, wordy phrases, nominalizations and expletives.
  • Prefer active voice and strong verbs.
  • Cut wasted words, not meaningful detail.
