Important Grammar Rules to Solve Error Corrections

Subject-Verb Agreement

The most common grammar mistake that students are tested on is subject-verb agreement. Here is an example:

The committee(a), made up of(b) several women, are(c) deciding on(d) the school budget next week. No error(e).

The mistake is choice “C”.

The subject of this sentence is “committee”, which is singular and therefore needs a singular verb. “Is” should replace “are” in this sentence.

This sentence contains a clause. The clause is the fragment of the sentence between the two commas, and it separates the subject from the verb. Therefore, you are tricked to think that the verb (“are”) should agree with “women”. In this case, read the sentence and eliminate the clause, so that the subject and the verb come directly after each other. By doing this, you will be able to tell if the subject does not agree with the verb.

Here is a second example:

We enjoyed the brilliant(a) sunshine of the beach(b) so much that day that when we left there was(c) only one couple and one lifeguard(d) still there. No error(e).

The mistake is in choice “C”.

“One couple and one lifeguard” is an example of a compound subject. A compound subject is when there is more than one person in the subject. A compound subject must always go with a plural verb. “Was” is a singular verb; “were” is a plural verb and should be used instead.

Subject-Pronoun Agreement

Another grammar mistake they ask about constantly is subject-pronoun agreement. This is a lot easier to understand than it sounds. An example will help you understand exactly what to look out for:

A smart tennis player such as Samantha is(a) someone who knows(b) how to  move around the court(c), can hit winners at the net, and controls their(d) emotions. No error(e).

The mistake is in choice D.

“Their” is a plural pronoun. The antecedent, and subject in the sentence, “player”, is singular. Instead of using “their”, the sentence should have used “her” as the pronoun.


Parallel Sentence Structure

A third grammar concept that is called parallel sentence structure. Here is an example of a sentence with a mistake in parallel sentence structure.

In a survey of(a) the school’s fifth graders, playing in gym class, painting in art class, participating in science labs and lunch time(b) were all mentioned repeatedly(c) as favorite activities in school(d)No error(e).

In this sentence, “lunch time” should be changed to “eating lunch.” Each of the items that the fifth graders mentioned start with an “-ing” word. This is called parallel sentence structure. Each item in a series should be written in the same grammatical form.


Subject/Object of Sentence

This is an important grammar rule.

The teacher asked Harry and I(a) if we could, due to(b) the upcoming exams, attend her(c) review class after(d) school. No error(e).

The mistake in this sentence is choice “A”.

In this sentence, “Harry and I” is the object of the sentence, which means “Harry and I” should be changed to “Harry and me”. If this was the subject of the sentence, then “Harry and I” would be correct.


Proper Verb Tense

Here is a sentence that contains an improper verb tense:

The three coaches decided not(a) to pick the team right after(b) practice that day, but they do(c) talk on the phone and made the final decisions that night(d)No error(e).

Choice C contains the mistake because “do” is in the present tense. “Do” should be changed to “did.” This entire sentence is written in the past tense. For example, “decided” is a verb used when something happened in the past.

Incorrect Comparisons

Examiner loves to test students on incorrect comparisons. Here is an example:

Sam felt(a) extremely confident going into(b) the final round of interviews, because his list of credentials was far more impressive(c) than his competitor(d)No error(e).

The mistake here is in choice D because Sam’s list of credentials is being compared to his competitor rather than his competitor’s list of credentials. Even though we may understand the sentence, “his competitor’s” or “his competitor’s list” needs to be used so that there is a proper comparison.


When comparing two things, use what’s called the comparative: more or a word that ends in –er, such as smarter:

Example: Of the two runners, he was the faster.

When comparing three or more than three things, use what’s called the superlative: most or a word that ends in –est, such as smartest:

Example: Of the three runners, she was the fastest.

Diction Error

Another grammar concept that is called diction. Diction basically means word choice. Here is a sentence that contains a diction error:

When the opera finally came to a conclusion(a) at nine, we still had not eaten dinner and wanted to decide quick(b) what type of food(c) everyone would be happy with(d)No error(e).

The mistake here is in choice B.

“Quickly” should be used instead of “quick.” If a verb, such as decide, is used in a sentence, an adverb is needed to describe how somebody is going to decide. “Quickly” is an adverb. Adverbs very frequently end in “-ly.” In this example, an adjective, “quick,” was used in a place where an adverb should have been. This is a common mistake used that students should really look out for.

A second type of diction error is when a slang type of expression is used instead of a more formal type of expression. Since there is some gray area between what is considered slang and what is considered formal. Here is a sentence with an error of this type:

The reason for(a) the poor attendance at(b) today’s annual party is because(c) the weather has been highly unpredictable(d) all week. No error(e).

The mistake here is in choice C.

The phrase “is because” is not grammatically correct in this sentence. The word “because” should not be used after the word “reason.” Instead, the phrase “is that” should be used.

Proper Number Agreement

This means that if a sentence has a plural subject then any phrases that describe the subject must be plural as well. Here is an example:

The travel tour through(a) Italy is(b) intended for(c) families with a young child(d)No error(e).

The mistake here is in choice D because the noun in the second part of the sentence, “families,” is plural and the phrase “with a young child” is singular. The phrase “with young children” should be used instead.

Unclear Pronouns

An unclear pronoun refers to a pronoun found in a sentence where it is unclear as to what the pronoun is referring to.

Sarah and Karen were(A) enjoying the hike up(B) the mountain until she(C) felt ill and they had(d) to turn back for home. No error(E).

The mistake in this sentence is choice “C” because it is unclear as to whether the pronoun “she” is referring to Sarah or Karen.

Words that go together

Here are some words that always go together:

(1) When you use preoccupation, you always use with: “He has a preoccupation with something.”

(2) When you use inconsistent, you always use with: “His words were inconsistent with something.”

(3) When you use regarded, you always use as: “She was regarded as the best.”

(4) When you use between, you always use and: “She was making a choice between this and this.”

(5) When you use either, you always use or.

(6) When you use neither, you always use nor.

(7) When you use each, you always use its.


So, these were the most Important Grammar Rules to Solve Error Corrections for Bank PO and Clerk examination.
