Parallelism (Structural Consistency)

Introduction

Parallelism (Structural Consistency) என்பது, ஒரு வாக்கியத்தில் வரும் சொற்கள், சொற்றொடர்கள் அல்லது clauses அனைத்தும் ஒரே grammatical pattern-ஐ பின்பற்றுவதை குறிக்கும். parallel structure-ஐ பராமரிப்பது வாக்கியங்களை தெளிவாகவும், சமநிலையுடனும், மேலும் professional-ஆகவும் மாற்றுகிறது. பல grammar கேள்விகள், nouns-ஐ verbs-உடன் கலப்பது அல்லது ஒரு list-இல் tense அல்லது pattern-ஐ மாற்றுவது போன்ற mismatched forms-ஐ நீங்கள் கண்டுபிடிக்க முடியுமா என்பதைச் சோதிக்கின்றன.

Pattern: Parallelism (Structural Consistency)

Pattern

முக்கிய கருத்து: ஒரு list அல்லது comparison-இல் உள்ள அனைத்துப் பகுதிகளும் ஒரே grammatical form-ஐ பின்பற்ற வேண்டும்.

- Verbs-க்கு ஒரே form பயன்படுத்தவும்: “to run, to swim, and to cycle” அல்லது “running, swimming, and cycling.”
- comparisons-இல் ஒரே structure-ஐ வைத்திருக்கவும்: “She likes dancing more than singing.”
- and, or, but போன்ற conjunctions-க்கு பின் consistency-ஐ பராமரிக்கவும்.
- either… or, neither… nor, not only… but also போன்ற correlative pairs-க்கு பின் parallel structure-ஐ கட்டாயமாக வைத்திருக்கவும்.

Step-by-Step Example

Question

Identify the sentence with correct parallel structure:

A. She likes reading, to write, and dancing.
B. She likes to read, writing, and to dance.
C. She likes reading, writing, and dancing.
D. She likes to read, to writing, and to dance.

Solution

  1. Step 1: Identify the list components.

    இந்த வாக்கியத்தில் “likes” என்ற Verb-க்கு பின் பல activities பட்டியலிடப்பட்டுள்ளன.

  2. Step 2: Apply the parallelism rule.

    எல்லா items-உம் ஒரே grammatical form-ஐ பயன்படுத்த வேண்டும் (அனைத்தும் -ing form அல்லது அனைத்தும் infinitive).

  3. Step 3: Check each option.

    Option C மட்டுமே consistent pattern-ஐ பயன்படுத்துகிறது: reading, writing, and dancing.

  4. Final Answer:

    She likes reading, writing, and dancing. → Option C.

  5. Quick Check:

    list-இல் உள்ள அனைத்தும் ஒரே “-ing” form-ஐ பின்பற்றுகின்றன → சரியான parallelism ✅

Quick Variations

1. Verb Forms Parallelism: “He came, saw, and conquered.”

2. Noun Parallelism: “Her goals include success, growth, and happiness.”

3. Correlative Conjunctions: “She is not only talented but also hardworking.”

4. Comparisons: “Swimming is easier than running.”

5. Infinitive Forms: “She wants to learn to code and to design.”

Trick to Always Use

  • Step 1: வாக்கியத்தில் உள்ள list, comparison, அல்லது pair-ஐ அடையாளம் காணுங்கள்.
  • Step 2: ஒவ்வொரு item-இன் grammatical form-ஐ சரிபார்க்கவும்.
  • Step 3: அனைத்தும் ஒரே structure-ஐ பின்பற்றுகிறதா என்பதை உறுதி செய்யுங்கள் (அனைத்தும் nouns, அனைத்தும் verbs, அனைத்தும் -ing forms, அல்லது அனைத்தும் infinitives).
  • Step 4: correlative pairs இருந்தால், இரு பகுதிகளுக்குப் பின்வரும் structure-ம் parallel-ஆ இருக்க வேண்டும்.

Summary

Summary

  • Parallelism என்பது lists மற்றும் comparisons-இல் grammatical forms ஒன்றுபோல இருப்பது.
  • consistent forms பயன்படுத்தவும்: அனைத்தும் infinitives அல்லது அனைத்தும் -ing forms அல்லது அனைத்தும் nouns.
  • correlative conjunctions strict parallel structure-ஐ அவசியமாக்குகின்றன.
  • Quick check: items பட்டியலிடப்பட்டுள்ளதா அல்லது ideas ஒப்பிடப்பட்டுள்ளதா → parallel structure-ஐச் சரிபார்க்கவும்.

Practice

(1/5)
1. Choose the sentence with correct parallel structure.
easy
A. She prefers skiing, skating, and hiking.
B. She prefers to ski, skating, and to hike.
C. She prefers skiing, to skate, and hiking.
D. She prefers to ski, skating, and hiking.

Solution

  1. Step 1: Identify the structure used for listed activities.

    Check whether items are gerunds (-ing) or infinitives (to + verb).

  2. Step 2: Apply the parallelism rule.

    All list items must match in grammatical form.

  3. Step 3: Evaluate options.

    Option A uses all gerunds: 'skiing, skating, and hiking' → consistent and correct.

  4. Final Answer:

    She prefers skiing, skating, and hiking. → Option A.

  5. Quick Check:

    All items are -ing forms → parallel ✅
Hint: Pick one form for lists (all -ing or all 'to' + verb).
Common Mistakes: Mixing gerunds and infinitives in the same list.
2. Choose the sentence that shows correct parallelism.
easy
A. She enjoys reading, writing, and painting.
B. She enjoys to read, writing, and to paint.
C. She enjoys reading, to write, and painting.
D. She enjoys to read, write, and painting.

Solution

  1. Step 1: Spot the list

    The sentence lists three activities that must use the same grammatical form.

  2. Step 2: Choose one form and use it consistently

    Option A uses all gerunds (-ing): reading, writing, painting - this is parallel.

  3. Step 3: Verify

    Other options mix infinitives and gerunds, breaking parallel structure.

  4. Final Answer:

    She enjoys reading, writing, and painting. → Option A.

  5. Quick Check:

    All list items share the same form (all -ing) - parallel ✅
Hint: Use all -ing or all ‘to + verb’ forms in a list - don’t mix.
Common Mistakes: Mixing infinitives and gerunds in the same list.
3. Which sentence is grammatically parallel?
easy
A. The teacher said we should listen carefully, think critically, and to speak clearly.
B. The teacher said we should listening carefully, think critically, and speak clearly.
C. The teacher said we should listen carefully, think critically, and speak clearly.
D. The teacher said listen carefully, thinking critically, and speak clearly.

Solution

  1. Step 1: Spot the auxiliary verb

    The sentence uses should, so verbs that follow must be in base form.

  2. Step 2: Ensure each verb matches the required form

    Option C uses base verbs after ‘should’: listen, think, speak - all parallel.

  3. Step 3: Verify

    Other options use mixed forms (infinitives, gerunds) and break parallelism.

  4. Final Answer:

    The teacher said we should listen carefully, think critically, and speak clearly. → Option C.

  5. Quick Check:

    After modal verbs like should/can/must, keep verbs in base form - parallel ✅
Hint: After modals (should, can, must) keep verbs in base form for parallel lists.
Common Mistakes: Using gerunds or infinitives after modal verbs.
4. 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.
5. 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.
