 Grammar Rules for GMAT Verbal

We will explore some grammatical concepts along with grammar rules.


Parallelism refers to when a sentence or phrase is constructed with identical grammatical structure throughout. Faulty parallelism occurs when parts of the sentence are not constructed in a similar grammatical structure. For example, “I like to dancing and to write”. The rectified sentence would look like, “I like dancing and writing”. The rules to use parallelism are as follows: 

  • Parallelism can be used when items in a list or series are being discussed. For example,  He went to the market, bought vegetables, and washed them. 
  • Parallelism can be rectified by coordinating conjunctions. Some coordinating conjunctions include — and, but, nor, so, and yet.
  • Parallelism should be used when you are comparing two things. For example, she likes writing letters more than reading them.


Gerunds refer to either nouns or verbs that end with -ing. Gerunds tend to make the sentence long and wordy. To avoid that, there are certain rules you need to follow.

  • You should avoid using gerunds in the beginning of sentences. You can do so if it is absolutely necessary. 
  • When using helping verbs such as am, been, are, and were, it has to be in the progressive tense. For example, “I have been going to pottery classes since January.”

Subject-Verb Agreement 

The subject-verb agreement refers to the relationship between a subject and verb, wherein they are in agreement. The agreement can be on the basis of number, case, or person. There are very simple rules you have to follow to avoid any errors; the rules are as follows: 

  • If you are using a singular noun, a singular verb can only accompany it. 
  • If you are using  a plural noun, a plural verb can only accompany it. 
  • However, the singular noun form takes on the letter “s”, whereas the plural noun form remains unchanged.


A modifier refers to nouns that serve as adjectives and adverbs that help describe objects or people. There is only one rule with the modifier, you need to add the modifier either before or after the noun you choose to describe.  

When Does a Faulty Comparison Occur? A faulty comparison occurs when the comparison to a noun or noun phrase is missing. You can avoid making any errors by following these rules: 

  • Make a comparison between two people or two things. Avoid comparing a person with an object or vice versa.
  • Do not make double comparisons as it will confuse the reader. For example, “She is more better at what she does than him”. The word “more” is redundant in this sentence, so we will rephrase it to, “She is better at what she does than him.” 

These are the basic grammatical concepts and grammar rules for the GMAT Verbal section that you have to be familiar with. Once you learn the GMAT grammar rules thoroughly, you can easily spot errors and rectify them quickly.
