1 Quick Introduction

English

Every board paper tests editing: a passage with one mistake in each line that you must find and fix. The secret is to scan systematically — check the verb, the subject-verb match, the article, the preposition, and the word choice. This chapter trains that editor's eye so errors jump out at you.

हिन्दी

हर बोर्ड पेपर editing जाँचता है: एक अनुच्छेद जिसकी हर पंक्ति में एक गलती होती है, जिसे आपको ढूँढकर ठीक करना है। रहस्य है व्यवस्थित ढंग से देखना — क्रिया, कर्ता-क्रिया मेल, article, preposition और शब्द-चयन जाँचें। यह अध्याय वही संपादक-दृष्टि विकसित करता है ताकि गलतियाँ स्वयं उभर आएँ।

2 A Real-Life Situation

Imagine this

You proofread a friend's application:

Line: I am writing to apply for the post of librarian which was advertise in your newspaper.

Fix: …which was advertised in your newspaper.

Why this form? One small slip — 'advertise' instead of 'advertised' — can spoil a formal letter. Editing is the skill of catching such errors before they cost you marks or credibility.

3 The Grammar Rule

Rule & Formula
Error typeIncorrectCorrect
TenseShe has wentShe has gone
AgreementThe boys isThe boys are
Articlean honest boy ✓ / a houran hour
Prepositionmarried withmarried to
Word formwas advertisewas advertised
Scan each line for: verb · agreement · article · preposition · word choice
He don't doesn't know nothing anything about it.

4 Categories of Error

Errors fall into a few predictable types — learn the list and check each one:

CategoryExample error → fix
TenseShe has went → has gone
Subject-verb agreementThe news are → is
ArticleShe is honest girl → an honest girl
PrepositionHe is good in maths → good at
PronounBetween you and I → you and me
Double negativeI don't know nothing → anything
Comparisonmore smarter → smarter
Redundancyreturn back → return

Structural errors include faulty parallelism and misplaced/dangling modifiers — covered in the next section.

1
Worked Example
Find and fix the error: He is more cleverer than his brother.
Solution

more cleverer → cleverer. Double comparatives are wrong.

2
Worked Example
Find and fix: I have been living here since five years.
Solution

since → for. Use 'for' with a length of time.

Key Points

  • Common error types: tense, agreement, article, preposition, pronoun
  • Also: double negatives, double comparatives, redundancy
  • Scan each line systematically in a fixed order

5 Modifiers, Parallelism & Passage Editing

Misplaced modifier: a describing word/phrase sits next to the wrong noun.

  • ❌ She almost drove the kids to school every day. → ✓ She drove the kids to school almost every day.

Dangling modifier: the opening phrase has no logical subject.

  • ❌ Walking to school, the rain started. → ✓ Walking to school, I felt the rain start.

Faulty parallelism: items in a list must share the same grammatical form.

  • ❌ She likes swimming, running, and to cycle. → ✓ swimming, running, and cycling.

Passage editing (CBSE format): each line has one error; write the wrong word and the correction. Omission exercises ask you to supply a missing word (often an article, preposition or helping verb).

1
Worked Example
Fix the parallelism: He is hardworking, honest, and a man of courage.
Solution

He is hardworking, honest, and courageous. — keep all items as adjectives.

2
Worked Example
Omission — supply the missing word: She is one of ___ best dancers.
Solution

the — 'one of the best …'.

Key Points

  • Keep a modifier next to the word it describes
  • An opening phrase must have a logical subject (no dangling)
  • List items must be parallel; passage editing = one error per line

10 Reading Practice

Editing task — one error per line is shown with its correction:

Line 1: Yesterday I go to the market. (go → went)
Line 2: I buyed some fresh vegetables. (buyed → bought)
Line 3: The shopkeeper was very honest man. (was very → was a very)
Line 4: He gave me a discount because I am a regular customer. (am → was)

Comprehension Questions

  2. What kind of error is 'buyed'?
  3. What word is missing in Line 3?
Answer Key
  1. 'Yesterday' signals a finished past action, which needs the simple past 'went'.
  2. A word-form (irregular verb) error — the past of 'buy' is 'bought'.
  3. The article 'a' — 'was a very honest man'.

Remember these

  • Scan each line: verb/tense → agreement → article → preposition → word choice
  • Watch for double negatives, double comparatives and redundancy
  • Keep modifiers next to the word they describe; avoid dangling phrases
  • List items must be parallel (same grammatical form)
  • Passage editing = one error per line; omission = supply a missing word
