Parallelism in English Grammar

Jul 8, 2025

Overview

This lecture discusses parallelism in English grammar, explaining its definition, importance, and rules for maintaining parallel structure in sentences.

Definition of Parallelism

  • Parallelism (parallel structure) means using similar grammatical forms within a sentence.
  • It provides balance, clarity, and rhythm to phrases by repeating grammatical forms.

Identifying and Correcting Non-Parallel Structures

  • Verbs in a list should have the same form (e.g., all in base form or all in -ing form).
  • Nouns should be grouped with nouns, adjectives with adjectives, and so on.
  • Mixing verb forms or grammatical types breaks parallelism.

Examples and Exercises

  • Correct: "dig, cook, dance, sing" (all base form verbs).
  • Correct: "locked, ate, took, looked, waited" (all past tense verbs).
  • Correct: "beautiful, simple, intelligent, active, lazy" (all adjectives).
  • Correct: "I like to jog, bake, paint, and watch movies." (all verbs in base/infinitive form).
  • Incorrect: Mixing "jog, bake, paint, and watching" (mixes infinitive and -ing forms).

Parallelism in Phrases and Clauses

  • Lists after a colon should be parallel (e.g., all noun phrases or all verb phrases).
  • Clauses joined with coordinating or correlative conjunctions must have similar structure.
  • Headings and outlines should use parallel structure, commonly noun phrases.

Importance of Parallel Structure

  • Parallel structure creates easier-to-read, balanced, and grammatically correct sentences.
  • Though not always strictly incorrect, lack of parallelism weakens writing clarity and style.

Key Terms & Definitions

  • Infinitive verb — base form of a verb, sometimes preceded by "to" (e.g., to sing).
  • Adjective — word describing a noun or pronoun.
  • Adverb — word describing a verb, adjective, or another adverb.
  • Clause — group of words with a subject and predicate, can be dependent or independent.
  • Correlative conjunction — paired conjunctions like either/or, neither/nor, not only/but also.
