Parallelism (Structural Consistency)

Introduction

Parallelism (structural consistency என்றும் அழைக்கப்படுகிறது) என்பது ஒரே sentence-இல் சம முக்கியத்துவம் கொண்ட ideas-க்கு ஒரே grammatical form-ஐ பயன்படுத்துவதை குறிக்கிறது. Parallel structure-ஐ பராமரிப்பது writing-இல் balance, clarity, மற்றும் rhythm-ஐ உருவாக்குகிறது.

Lists அல்லது comparisons-இல் verbs, nouns, அல்லது phrases ஒரே grammatical pattern-ஐ பின்பற்றாதபோது faulty parallelism ஏற்படுகிறது.

Pattern: Parallelism (Structural Consistency)

Pattern

Ideas series, comparison, அல்லது list-ஆக வழங்கப்படும்போது, அனைத்து elements-உம் ஒரே grammatical form-ஐ பயன்படுத்த வேண்டும் (e.g., verb form, noun form, infinitive form).

  • Correct: She likes reading, writing, and painting.
  • Incorrect: She likes to read, writing, and painting.

Step-by-Step Example

Question

Choose the sentence with correct parallel structure:

  1. He wanted to study medicine, engineering, and become a pilot.
  2. He wanted to study medicine, to study engineering, and become a pilot.
  3. He wanted to study medicine, to study engineering, and to become a pilot.
  4. He wanted to studying medicine, engineering, and to become a pilot.

Solution

  1. Step 1: Identify the pattern

    இந்த sentence மூன்று activities-ஐ list செய்கிறது; அவை அனைத்தும் ஒரே grammatical form-ஐ பின்பற்ற வேண்டும்.

  2. Step 2: Check for consistency

    Sentence infinitive form “to study”-யுடன் தொடங்குவதால், அனைத்து items-உம் balance-க்காக infinitive form-இலேயே இருக்க வேண்டும்.

  3. Step 3: Compare the options

    Option C மட்டும் consistent structure-ஐ பராமரிக்கிறது: to study medicine, to study engineering, and to become a pilot.

  4. Final Answer:

    He wanted to study medicine, to study engineering, and to become a pilot. → Option C.

  5. Quick Check:

    Parallelism = same grammatical form → (to study, to study, to become) ✅

Quick Variations

1. Lists-இல் consistent verb forms-ஐ பயன்படுத்துங்கள் (e.g., “running, jumping, swimming”).

2. Comparisons-இல் parallelism-ஐ பராமரியுங்கள் (e.g., “better to give than to receive”).

3. ஒரே structure-இல் infinitives மற்றும் gerunds-ஐ கலக்க வேண்டாம்.

Trick to Always Use

  • Step 1: Compare அல்லது list செய்யப்படும் elements-ஐ கண்டறியுங்கள்.
  • Step 2: ஒவ்வொன்றும் ஒரே grammatical form-ஐ பின்பற்றுகிறதா என்று உறுதி செய்யுங்கள் (noun-noun, verb-verb, adjective-adjective).
  • Step 3: Sentence-ஐ சத்தமாக வாசியுங்கள் - balance இல்லாமல் தோன்றினால் structural mismatch-ஐ சரிபாருங்கள்.

Summary

Summary

  • Parallelism ஒரே வகை ideas-ஐ ஒரே grammatical form-இல் வைத்திருக்கும்.
  • Consistent patterns-ஐ பயன்படுத்துங்கள் (e.g., அனைத்தும் infinitives, அனைத்தும் -ing forms, அல்லது அனைத்தும் adjectives).
  • Readability, rhythm, மற்றும் expression clarity-ஐ மேம்படுத்துகிறது.

Practice

(1/5)
1. Identify the part with incorrect parallel structure: 'He likes to jog, swim, and going to the gym.'
easy
A. to jog
B. swim
C. going to the gym
D. No error

Solution

  1. Step 1: Identify the list elements.

    The sentence lists three activities after 'likes'.

  2. Step 2: Apply the parallelism rule.

    All items should use the same grammatical form (all infinitives or all gerunds).

  3. Step 3: Spot the mismatch.

    'to jog' (infinitive) and 'swim' (bare verb/infinitive sense) are not the same form as 'going to the gym' (gerund phrase) → inconsistent.

  4. Final Answer:

    going to the gym → Option C.

  5. Quick Check:

    Make all items the same: 'to jog, to swim, and to go to the gym' or 'jogging, swimming, and going to the gym' ✅
Hint: Make list items the same form (all -ing or all 'to' + verb).
Common Mistakes: Mixing infinitives and gerunds in the same list.
2. Choose the correct connector to maintain parallel structure: 'Either he will start the project ___ he will delay it.'
easy
A. or
B. nor
C. and
D. but

Solution

  1. Step 1: Identify the correlative pair.

    The sentence uses 'Either ... ___' which requires a parallel correlative partner.

  2. Step 2: Apply the parallelism/correlative rule.

    'Either' pairs with 'or' to present two alternatives.

  3. Step 3: Choose the correct connector.

    The correct pair is 'Either ... or' → 'Either he will start the project or he will delay it.'

  4. Final Answer:

    or → Option A.

  5. Quick Check:

    'Either ... or' (alternatives) ✅
Hint: Pair correlative conjunctions correctly: either/or, neither/nor, not only/but also.
Common Mistakes: Using the wrong partner (e.g., 'either ... and' or 'neither ... or').
3. Identify the part with incorrect parallel structure: 'The job requires planning, organizing, leading, and to control resources.'
medium
A. planning
B. organizing
C. leading
D. to control resources

Solution

  1. Step 1: Identify the series of requirements.

    The list contains 'planning, organizing, leading, and to control resources'.

  2. Step 2: Apply parallelism rule.

    'planning', 'organizing', and 'leading' are gerund (-ing) forms; the last item is an infinitive phrase 'to control resources' → inconsistent.

  3. Step 3: Choose the incorrect part.

    'to control resources' should be 'controlling resources' to match the others.

  4. Final Answer:

    to control resources → Option D.

  5. Quick Check:

    Convert to gerund: 'planning, organizing, leading, and controlling resources' ✅
Hint: Match the form used by the first items in the list for the rest.
Common Mistakes: Leaving one item in a different verb form and missing the mismatch on a long phrase.
4. Find the sentence that follows parallel structure in comparison.
medium
A. It is easier to start than to finish a task.
B. It is easier to start than finishing a task.
C. It is easier starting than to finish a task.
D. It is easy to start rather than finishing a task.

Solution

  1. Step 1: Identify the comparison

    'Than' compares two actions - both sides must use the same grammatical form.

  2. Step 2: Match forms across the comparison

    Option A uses infinitives on both sides: to start and to finish, so it is parallel.

  3. Step 3: Verify

    Other choices mix -ing forms and infinitives, which breaks the parallel structure in comparison.

  4. Final Answer:

    It is easier to start than to finish a task. → Option A.

  5. Quick Check:

    On both sides of 'than' use the same verb form (both ‘to + verb’ or both ‘-ing’) - parallel ✅
Hint: Keep the same verb form on both sides of comparisons (than/as).
Common Mistakes: Mixing infinitives and gerunds in comparative structures.
5. Select the sentence that maintains parallel structure in a list of expectations.
medium
A. The manager expects employees to be punctual, to work efficiently, and cooperation.
B. The manager expects employees being punctual, efficient, and cooperative.
C. The manager expects employees to be punctual, efficient, and cooperating.
D. The manager expects employees to be punctual, efficient, and cooperative.

Solution

  1. Step 1: Identify the main verb phrase

    The phrase expects employees to be is followed by qualities - keep those qualities in the same form.

  2. Step 2: Use the same grammatical form for each item

    Option D uses three adjectives (punctual, efficient, cooperative) that match the structure 'to be + adjective'.

  3. Step 3: Verify

    Other options mix nouns, gerunds, or incomplete forms, breaking parallel structure.

  4. Final Answer:

    The manager expects employees to be punctual, efficient, and cooperative. → Option D.

  5. Quick Check:

    After 'to be' list adjectives (not verbs or nouns) - parallel ✅
Hint: After 'to be', list adjectives (punctual, efficient, cooperative) - keep form consistent.
Common Mistakes: Mixing adjectives with verbs/nouns in the same list.
