Error Spotting
🔒 Log in to trackA sentence is split into parts and one part carries a grammatical fault. Errors cluster in a short list — agreement, tense, articles, prepositions, pronouns, correlative pairs and comparison — so a fixed audit order (SVA → tense → article → preposition → pronoun → pairs → word choice) converts this into the most mechanical scoring topic in the section.

Question patterns exams keep repeating
Taken from previous-year papers. If a pattern is marked "very common", expect to see it in your exam.
Subject-verb agreement error
very commonThe verb is far from its subject, or the sentence has 'of ...', 'as well as', 'one of', 'the number of'.
Cover the phrase between the subject and the verb, then find the real subject.
Match the verb to it: 'one of' and 'each of' take a singular verb.
Find the error: 'The number of accidents on this highway / have fallen / after the new signals were installed.'
'The number of' means one count: singular
The plural word 'accidents' is only a trap
The error is in part 2
Answer: it should be has fallen
Tense error
very commonA time word like 'ago', 'yesterday', 'since', 'as soon as' does not match the verb.
Circle the time words first, then check the verb against them.
After when / as soon as / if / until, use the present tense for the future, not 'will'.
Find the error: 'I will return your camera / as soon as / I will reach / home tomorrow.'
'as soon as' starts a time clause
A future time clause uses the simple present
'will' belongs only in the main clause
Answer: it should be I reach
Gerund or infinitive error
very commonOne verb follows another, like 'denied to have' or 'enjoys to play'.
Verbs like enjoy, avoid, deny, suggest take -ing.
Verbs like want, decide, agree, refuse take to + verb.
Find the error: 'She denied to have / taken the file, / but the register / proved otherwise.'
'deny' takes the -ing form
'denied to have' breaks this rule
The error is in part 1
Answer: it should be denied having
Article error (a / an / the)
commonA part has a, an or the before a noun, often before words like MLA, hour, university.
Say the next word aloud.
Vowel sound: an. Consonant sound: a.
Find the error: 'She reached the hall / an hour late / because of / a MLA's convoy.'
'MLA' is said 'em-el-ay', which starts with a vowel sound
So it needs 'an'
'an hour' is correct because the h is silent
Answer: it should be an MLA's convoy
Wrong preposition
very commonA verb or adjective sits next to a preposition that looks fine but is not the fixed one, like 'comply by'.
Learn each pair as one chunk: comply with, insist on, accused of, capable of.
Check the preposition after every verb and adjective.
Find the error: 'The coach did not agree / with the umpire's decision, / but he complied / by the rules.'
The fixed pair is 'comply with'
'comply by' is wrong
The error is in part 4
Answer: it should be complied with
Pronoun and joining word error
commonA pronoun is in the wrong form, or a reported question has two joining words like 'that whether'.
After a preposition use me / him / them, not I / he / they.
A reported question needs only one joining word: asked why, wanted to know whether.
Find the error: 'Mother wanted to know / that whether / I had locked / the back door.'
A reported yes/no question takes 'whether' or 'if'
'that whether' puts two joining words together
The error is in part 2
Answer: it should be just whether
Comparison error
commonA sentence compares things: 'more better', 'than any city', 'superior than'.
Use only one comparison marker (better, not more better).
When a thing is compared with its own group, add 'other'.
Find the error: 'The summer of Nagpur / is harsher than / any city / in Maharashtra.'
Nagpur is itself a city in Maharashtra
It cannot be harsher than itself
The error is in part 3
Answer: it should be any other city
Repeated or confused word
commonA word repeats an idea already present (return back, more better), or two similar words are mixed up (advice / advise).
Ask if a nearby word already says the same thing, then cut the extra one.
For look-alike words, decide if the slot needs a noun or a verb.
Find the error: 'This year's harvest / is more better / than the last one's, / thanks to the rains.'
'better' already means 'more good'
Adding 'more' doubles the comparison
The error is in part 2
Answer: it should be is better
Question tag error
occasionalA statement ends with a short tag like 'isn't it?' or 'doesn't he?'.
The tag repeats the helping verb and flips positive/negative.
Words like never, rarely, hardly make a sentence negative, so the tag is positive.
Find the error: 'Suresh rarely misses his morning walk, doesn't he?'
'rarely' makes the statement negative
So the tag must be positive
'doesn't he' is negative again
Answer: it should be does he?
