Lesson in Module 5: Style and Editing

Open module overview

Parallelism and Comparison

Keep matched ideas in matched grammatical form and compare like with like.

Module Module 5: Style and Editing
Estimated time 95 min
Level Upper Intermediate

Overview

Parallelism is the principle that similar ideas should appear in similar grammatical forms. Comparison is the principle that the things being compared must be logically comparable. Both are central to elegant, intelligent writing.

Compare:

  • She likes reading, to travel, and photography.
  • She likes reading, traveling, and photography.

The second version feels better because the structure matches. Now compare:

  • My salary is higher than a teacher.
  • My salary is higher than a teacher’s salary.

The second version is logical because it compares salary with salary, not salary with person.

Chapter Map

  1. First, you will study the logic of parallel structure.
  2. Then, you will learn how comparisons work grammatically.
  3. After that, you will study correlative structures and comparison errors.
  4. Finally, you will practice editing for balance and logic.

Full Definitions

Parallelism

Parallelism means expressing similar or coordinated ideas in matching grammatical forms.

Comparison

Comparison means showing difference or similarity between two or more things.

Correlative pair

A correlative pair is a linked structure such as:

  • either…or
  • neither…nor
  • not only…but also

Learning Objectives

  • Create parallel lists and paired structures.
  • Keep coordinated ideas in matching form.
  • Build logical comparisons.
  • Use comparative and superlative forms accurately.
  • Edit awkward or illogical comparison structures.

The Big Idea

Readers expect form to reflect meaning. If two ideas are equal or linked, their grammar should look balanced. If two things are compared, they must belong to the same logical category.

Section 1: Parallelism in Lists

Items in a list should follow the same grammatical pattern.

Example 1

  • Weak: The course develops writing, to analyze arguments, and confidence in editing.
  • Better: The course develops writing, argument analysis, and editing confidence.

Example 2

  • Weak: She enjoys singing, to dance, and drawing.
  • Better: She enjoys singing, dancing, and drawing.

Example 3

  • Strong: The workshop focused on planning, drafting, revising, and editing.

Section 2: Parallelism with Coordinating Conjunctions

When and, or, or but join units, the joined parts should balance if they play the same rhetorical role.

Example 4

  • Weak: The proposal was ambitious but lacked clarity and too much repetition.
  • Better: The proposal was ambitious but lacked clarity and contained too much repetition.

Example 5

  • Strong: The report was clear, concise, and persuasive.

Section 3: Parallelism in Paired Ideas

Parallelism matters especially when ideas are presented as a pair.

Example 6

  • Weak: The goal is to improve accuracy and that students write more confidently.
  • Better: The goal is to improve accuracy and to help students write more confidently.

Example 7

  • Strong: The program aims to reduce errors and to increase confidence.

Section 4: Correlative Structures

Correlative pairs need balanced structure after both parts.

Either...or

Example 8

  • Correct: You can either revise tonight or wake up early tomorrow.

Neither...nor

Example 9

  • Correct: Neither the schedule nor the location has changed.

Not only...but also

Example 10

  • Weak: She not only explained the method clearly but also confidence.
  • Better: She not only explained the method clearly but also spoke with confidence.

Example 11

  • Strong: The course not only improves grammar but also builds editing discipline.

Section 5: Comparison Basics

Comparisons usually use:

  • -er or more
  • than
  • superlative forms such as best, most useful

Example 12

  • Sentence: This draft is clearer than the last one.

Example 13

  • Sentence: Her explanation was more convincing than mine.

Example 14

  • Sentence: That was the most useful session of the semester.

Section 6: Compare Like with Like

This rule prevents many awkward sentences.

Example 15

  • Illogical: The salary of a doctor is higher than a teacher.
  • Logical: The salary of a doctor is higher than a teacher’s salary.

Example 16

  • Illogical: The climate in Mumbai is hotter than Delhi.
  • Logical: The climate in Mumbai is hotter than the climate in Delhi.
  • Natural shorter form: Mumbai is hotter than Delhi.

Example 17

  • Illogical: Her dedication is greater than any student in the class.
  • Logical: Her dedication is greater than that of any student in the class.

Section 7: Comparatives and Ellipsis

English often omits repeated words if the meaning stays clear.

Example 18

  • Full: Her presentation was more detailed than my presentation.
  • Natural: Her presentation was more detailed than mine.

Example 19

  • Full: The new system is faster than the old system.
  • Natural: The new system is faster than the old one.

These shortened forms are elegant when the meaning remains obvious.

Section 8: Double Comparatives and Wrong Forms

Avoid double comparative marking.

Example 20

  • Wrong: more easier
  • Right: easier

Example 21

  • Wrong: more better
  • Right: better

Example 22

  • Wrong: the most quickest route
  • Right: the quickest route

Section 9: Comparison with As...As

Use as…as for equal comparison.

Example 23

  • Sentence: This chapter is as useful as the previous one.

Example 24

  • Sentence: She is not as confident as her brother.

Section 10: Comparison and Parallel Meaning in Longer Sentences

Example 25

  • Weak: The internship taught me how to work with deadlines, solving communication problems, and that feedback matters.
  • Better: The internship taught me how to work with deadlines, solve communication problems, and value feedback.

Example 26

  • Weak: The city is more crowded than when I was a child.
  • Better: The city is more crowded now than it was when I was a child.

The revision clarifies what exactly is being compared.

Common Mistakes and Why They Happen

Mistake 1

  • WRONG: She likes to swim, reading, and to paint.
  • RIGHT: She likes swimming, reading, and painting. / She likes to swim, to read, and to paint.

Why learners make it:

  • They mix structures inside one list.

Mistake 2

  • WRONG: My office is larger than my colleague.
  • RIGHT: My office is larger than my colleague’s office. / My office is larger than my colleague’s.

Why learners make it:

  • They compare a place with a person.

Mistake 3

  • WRONG: He is more smarter than I thought.
  • RIGHT: He is smarter than I thought.

Why learners make it:

  • They add two comparative markers at once.

Mistake 4

  • WRONG: She not only writes clearly but also with confidence.
  • POSSIBLE improvement: She not only writes clearly but also speaks with confidence.

Why learners make it:

  • They use a second element that does not balance clearly with the first.

Practice Plan

  1. Rewrite ten faulty lists to make them parallel.
  2. Correct ten illogical comparisons.
  3. Write five sentences with not only…but also, five with either…or, and five with as…as.
  4. Edit a paragraph to improve both balance and comparison logic.
  5. Compare two people, two places, and two systems in a short paragraph using accurate parallel structure.

Story Lab

”Story Lab: The Debate Reflection”

“After the intercollegiate debate, Kavya wrote that the event had taught her three things: how to structure evidence, how to listen under pressure, and how to answer quickly without losing precision. She also noted that the strongest teams were not only well informed but also exceptionally disciplined.”

“When she compared her own team with last year’s finalists, she did not claim that they were simply ‘better than those students.’ Instead, she wrote that their preparation was more systematic, their transitions were smoother, and their evidence was more sharply organized than that of the previous team. The comparison sounded fair because it compared like with like.”

Final Summary

Parallelism gives writing balance. Comparison gives writing logic. Together they help sentences sound educated, controlled, and precise. When ideas match in importance, let them match in form. When things are compared, compare equivalent things.
