Editing and Omission Exercises for CBSE Class 9 & 10 (Solved Examples + Practice Sets)
Introduction: Decoding Editing and Omission
In the CBSE English Language and Literature examination (Classes 9 and 10), Editing & Omission are core components of the Integrated Grammar section. These questions test practical, applied grammar in a running context rather than isolated rules.
The Fundamental Difference
Feature | Editing (Error Detection & Correction) | Omission (Insertion of Missing Word) |
Task | Spot an incorrect word in each line and replace it with the grammatically correct word. | Identify a missing word between two words in each line and provide the complete context. |
Output Format | Error Correction | Word Before Missing Word Word After |
Grammar Scope | Tenses, Subject-Verb Concord, Determiners, Prepositions, Modals, Connectors, Pronouns. | Articles, Auxiliary Verbs, Prepositions, Conjunctions, Relative Pronouns. |
4-Step Strategy to Score Full Marks in Editing & Omission
Step 1: Read the Entire Passage First (Do Not Start Line-by-Line)
Before writing a single word, read the whole paragraph from start to finish. This helps determine:
The Global Tense: Is the text describing a historical event (Past Tense), a scientific fact (Simple Present), or an ongoing process?
The Voice & Tone: Is it written in Active Voice, Passive Voice, or reported speech?
The Core Subject: Who or what is the main subject (singular or plural)?
Step 2: Use the "P-T-S-D-C" Diagnostic Checklist
When analyzing each line, evaluate the words in this order:
1. P – Prepositions & Pronouns: Is the preposition correctly paired? Does the pronoun agree in number and gender with its antecedent?
2. T – Tenses & Verb Forms: Does the finite verb match the overall time frame of the passage? Is a bare infinitive used after a modal auxiliary?
3. S – Subject-Verb Agreement (Concord): Does a singular subject have a singular verb? Check intervening phrases (along with, as well as, together with).
4. D – Determiners & Articles: Is an indefinite article (a/an) used where a specific reference (the) is needed? Are quantifiers (much, many, few, little) used correctly?
5. C – Conjunctions & Connectors: Does the connector show contrast (although, but), reason (because, since), or addition (and, moreover) correctly?
Step 3: Check Clause Boundaries (Crucial for Omission)
In omission tasks, words are most frequently omitted at structural joints:
Between a subject and its main verb (missing auxiliary: is, was, has, have).
Between a verb and a following noun phrase (missing preposition: at, in, to, of).
Between two independent or dependent clauses (missing connector or relative pronoun: that, which, who, when).
Before a singular countable noun (missing article: a, an, the).
Step 4: Re-read the Corrected Passage
Once you complete your answers, read the entire paragraph with your corrections or inserted words in place. If the sentence rhythm stumbles or the logic breaks, re-examine that specific line.
Common Grammar Traps in CBSE Examinations
1. Modal + First Form of Verb ():
Modals (can, could, may, might, must, should, will, would) are always followed by the base form of the verb without 'to' (He can sings He can sing).
2. One of + Plural Noun + Singular Verb:
Example: "One of the boys were present" is incorrect "One of the boys was present."
3. Uncountable Nouns with Countable Determiners:
Example: "He gave me many advices" is incorrect "He gave me much advice" or "pieces of advice."
4. Since vs. For:
Use since for a specific point in time (since 2010, since morning) and for for a duration (for five years, for two hours).
Section 1: Solved Editing Exercises
Passage 1 (Editing)
The following passage has not been edited. There is an error in each line. Identify the error and write the correction in your answer sheet.
Line No. | Text | Error | Correction |
(a) | Renewable energy sources is becoming increasingly | is | are |
(b) | popular around a world as nations attempt to | a | the |
(c) | reduce their reliance on fossil fuels. Solar power, | their | (Correct) |
(d) | for instance, utilize photovoltaic cells to convert | utilize | utilizes |
(e) | sunlight in electricity without causing pollution. | in | into |
Explanations:
(a) Subject-Verb Agreement: The subject is "Renewable energy sources" (plural), which requires the plural auxiliary verb are.
(b) Determiner/Article: "World" is a unique noun that takes the definite article the (the world).
(d) Subject-Verb Agreement: "Solar power" is an uncountable/singular subject; therefore, the third-person singular present verb utilizes is required.
(e) Preposition: The verb "convert" is followed by the preposition into when indicating a change of state (convert sunlight into electricity).
Passage 2 (Editing)
Identify the incorrect word and supply the correction for the passage below.
Line No. | Text | Error | Correction |
(a) | Last week, our school organize an educational trip | organize | organized |
(b) | to the National Science Museum. Every students was | students | student |
(c) | given a worksheet to record their observations. | their | his / her |
(d) | We saw many models who demonstrated physical | who | which / that |
(e) | laws, making learning both engaging and fun. | (Correct) |
Explanations:
(a) Tense: "Last week" denotes a completed past action, requiring the simple past tense organized.
(b) Determiner Rule: The distributive determiner "Every" is always followed by a singular countable noun (student).
(c) Pronoun Agreement: "Every student" is singular, so formal agreement requires his/her (or rephrasing; in CBSE, matching singular antecedent is standard).
(d) Relative Pronoun: "Models" are inanimate objects, so the relative pronoun must be which or that, not "who" (which refers to people).
Section 2: Solved Omission Exercises
Passage 1 (Omission)
In the following passage, one word has been omitted in each line. Write the missing word along with the word that comes before and the word that comes after it.
Line No. | Passage Text | Word Before | Missing Word | Word After |

(b) | promotes physical, mental spiritual health. | mental | and | spiritual |
(c) | It helps regulating breathing patterns | helps | in | regulating |
(d) | and calms nervous system effectively. | calms | the | nervous |
(e) | Regular practice brings harmony the body. | harmony | to / in | the |
Explanations:

(b) Missing Conjunction: A coordinating conjunction and is required between the parallel adjective modifiers ("mental" and "spiritual").
(c) Missing Preposition: "Helps in doing something" or "helps to regulate" (here, before the gerund "regulating", the preposition in is missing).
(d) Missing Article: "Nervous system" is a specific anatomical system requiring the definite article the.
(e) Missing Preposition: The verb-noun construction "brings harmony..." requires the preposition to or in before the recipient "the body".
Section 3: Practice Sets for Self-Evaluation

It plays crucial role in the national economy. (e) ________ ________ ________
Answer Key & Explanations for Practice Sets
Practice Set 1 (Editing Answers)
(a) Error: on | Correction: for (Explanation: The adjective "known" takes the preposition "for" when specifying a reason/reputation).
(b) Error: help | Correction: helps (Explanation: "This phenomenon" is a singular noun; requires singular verb "helps").
(c) Error: by | Correction: with (Explanation: "Communicate" takes "with" when interacting with others).
(d) Error: its | Correction: their (Explanation: The subject "They" / "Chameleons" is plural, so the possessive pronoun must be "their").
(e) No error / Line completes the context.
Practice Set 2 (Omission Answers)
(a) Before: of | Missing: the | After: largest (Superlative adjectives always take the definite article 'the').
(b) Before: millions | Missing: of | After: passengers (Expressions of indefinite quantity take 'of': millions of passengers).
(c) Before: across | Missing: the | After: length (Fixed idiomatic phrase: 'across the length and breadth of').
(d) Before: towns | Missing: but | After: also (Correlative conjunction pair: 'not only... but also').
(e) Before: plays | Missing: a | After: crucial (Singular countable noun phrase 'crucial role' requires indefinite article 'a').
Summary: Quick Checklist for Exam Day
Treat grammar questions as interconnected sentences, not isolated fragments.
Always write both the Error and Correction clearly in two distinct columns.
For Omission, always verify that your three-word sequence (Before – Missing – After) reads naturally and logically.
