Error Detection and Correction

Overview

Error Detection and Correction is a high-scoring section in HTET English that tests your command over grammar rules in practical application. Rather than testing grammar in isolation, these questions present sentences with embedded mistakes—your job is to identify which part contains the error and know how to fix it.

This topic appears consistently across all three HTET levels (PRT, TGT, PGT), typically carrying 3-5 questions. Mastery here has a multiplier effect: the same grammar knowledge helps you in reading comprehension, sentence improvement, and even the pedagogy section where you must understand common learner errors. The key is pattern recognition—most errors fall into predictable categories that repeat across exams.

Key Concepts

• **Subject-Verb Agreement**: The verb must match the subject in number (singular/plural), regardless of intervening phrases. "The list of items is ready" (not "are").

• **Tense Consistency**: A sentence or related clauses should maintain the same tense unless there's a logical reason to shift. "He came and sat down" (not "comes and sat").

• **Pronoun-Antecedent Agreement**: Pronouns must agree with their antecedents in number and gender. "Each student must bring his or her book" (not "their book" in formal usage).

• **Parallelism**: Items in a list or comparison must follow the same grammatical structure. "She likes reading, writing, and swimming" (not "to swim").

• **Modifier Placement**: Adjectives and adverbs must be placed close to the words they modify. "She almost drove the car for two hours" vs "She drove the car for almost two hours."

• **Article Usage**: Use "a" before consonant sounds, "an" before vowel sounds, and "the" for specific nouns. "An hour" (silent h), "a university" (y-sound).

• **Preposition Errors**: Fixed prepositions go with specific words. "Interested in" (not "interested for"), "congratulate on" (not "congratulate for").

• **Redundancy and Wordiness**: Avoid repetitive or unnecessary words. "Return back" should be just "return"; "12 noon" not "12 noon in the afternoon."

Key Facts

| Error Type | Wrong | Correct | |------------|-------|---------| | Subject-Verb | The news are good | The news is good | | Tense | He goes yesterday | He went yesterday | | Article | He is a honest man | He is an honest man | | Preposition | Superior than | Superior to | | Pronoun | Everyone brought their | Everyone brought his/her | | Parallelism | To sing and dancing | To sing and to dance / singing and dancing | | Comparison | More better | Better | | Redundancy | Revert back | Revert |

**Common confusing pairs:**

• Beside (next to) vs Besides (in addition to)
• Fewer (countable) vs Less (uncountable)
• Between (two) vs Among (more than two)
• Lie (to recline) vs Lay (to put something)

Worked Examples

**Example 1: Subject-Verb Agreement**

*Question*: Find the error: "One of the boys (A)/ have not done (B)/ their homework (C)/ No error (D)"

*Solution*:

• Step 1: Identify the subject. "One" is the subject, not "boys."
• Step 2: "One" is singular, so the verb must be singular.
• Step 3: "have" should be "has."
• **Answer: (B)** — Correct sentence: "One of the boys has not done his homework."

**Example 2: Preposition Error**

*Question*: Find the error: "She is (A)/ angry on me (B)/ for no reason (C)/ No error (D)"

*Solution*:

• Step 1: Check preposition combinations. "Angry" takes "with" for persons.
• Step 2: "Angry on" is incorrect; it should be "angry with."
• **Answer: (B)** — Correct sentence: "She is angry with me for no reason."

**Example 3: Tense and Parallelism**

*Question*: Find the error: "He not only played (A)/ the guitar but also (B)/ singing a song (C)/ No error (D)"

*Solution*:

• Step 1: Check "not only...but also" structure—both parts need parallel forms.
• Step 2: "played" (past verb) must match with "sang" (past verb), not "singing."
• **Answer: (C)** — Correct sentence: "He not only played the guitar but also sang a song."

Common Mistakes

• **Ignoring collective nouns**: Students treat "team," "committee," "jury" as plural. → These are singular in British English (used in India): "The team is ready."

• **Confusing "each/every" with plural verbs**: "Each of the students have" feels right because "students" is nearby. → "Each" and "every" are always singular: "Each of the students has."

• **Using double comparatives**: "More faster," "most tallest" seem emphatic. → Use either "more" or "-er," never both: "faster" or "more rapid."

• **Wrong preposition with time expressions**: "On yesterday," "in last week." → No preposition before yesterday/today/tomorrow/last/next: "He came yesterday."

• **Assuming longer sentences have errors**: Students overthink complex sentences. → Sometimes "No error" is correct. Trust your analysis—if every part is grammatically sound, choose (D).

• **Overlooking article errors with sounds**: "A European," "An university" based on spelling. → Articles depend on sound: "A European" (y-sound), "A university" (y-sound), "An hour" (vowel sound).

Quick Reference

• **Subject-Verb**: Find the real subject; ignore phrases between subject and verb.
• **Collective nouns** (team, jury, crowd): Singular verb in Indian English.
• **"One of the + plural noun"**: Verb agrees with "one" (singular).
• **Neither/Either**: Singular when alone; with "nor/or," verb matches the nearest subject.
• **Superior/inferior/senior/junior**: Use "to," never "than."
• **No double negatives**: "Hardly," "scarcely," "barely" are already negative—don't add "not."
