By Dr Tanya Singh, Dean Academics, Noida International University

CAT 2025 Preparation Strategy: Having a good vocabulary is crucial for effective preparation for the CAT 2025 exam, and substantially for the Verbal Ability and Reading Comprehension (VARC) section. Most candidates make the same errors, and when they do, this reduces their chances of reading longer passages, getting all the questions correct, and being able to convey what they have read. The first step is to identify the errors to improve. This article describes the ten most common vocabulary errors made by CAT aspirants.

Reading quality newspapers, magazines, and books is a simple way to grow your vocabulary while preparing for CAT 2025. It is advisable to keep a running list of new and interesting words and review them often to build your verbal ability over time. Read below the common mistakes to avoid while preparing for the CAT Verbal Ability and Reading Comprehension (VARC) section.

Memorising Words Without Context

Students frequently have long lists of words in mind, but have no idea what they mean in a sentence or how to use them in a sentence. Knowing the meaning of a word is significant, but learning how to use a word in context within a sentence is to learn it in context. Furthermore, the word can have a meaning you understand, but it may not be the right word because it contains a different connotation. In most instances, it is the context that causes the problem when filling out a sentence or doing comprehension or a parajumble.

Ignoring Word Forms

Words in English can take on various forms: nouns, verbs, adjectives, and adverbs. The meaning or function of the word is subject to its form. Words such as ‘profound’ (adjective) and ‘profundity’ (noun) may be related, but do not function in the same way in a sentence. Aspirants may misuse words by ignoring forms or rules about word forms, resulting in very subtle but serious comprehension errors and writing tasks.

Confusing Similar-Sounding Words

Words that are similar in appearance to each other or sound similar to each other can be easily confused. Examples of issues related to word form are ‘affect’ and ‘effect,’ ‘complement’ and ‘compliment,’ and ‘elicit’ and ‘illicit.’ Using the wrong word choice can be harmful to the student on the CAT when the question demands the utmost precision in your understanding of the word employed. When taking one error of a word with the correct word, you skew the meaning of a passage or sentence, and as a student, you must make sure you have the correct word to select the accurate answer.

Excessive Use of Synonyms

Synonyms are valuable, yet overuse can easily result in their misuse. Words may be synonymous in one respect but not necessarily replaceable in all references. For instance, ‘enormous’ and ‘immense’ are synonymous, but ‘enormous gratitude’ is meaningless, while ‘immense gratitude’ would be appropriate. Misusing a word often demonstrates ignorance and can confuse the reader’s understanding of the passage when working with reading comprehension passages.

Ignoring Antonyms

Often, when studying for exams, people are more concerned with understanding words’ synonyms than their antonyms, and exam preparation should also consider the opposite meaning of words. Understanding words that have the opposite meaning is important because questions testing logical reasoning and analogy, as well as reading comprehension, all rely on understanding words that are antonyms too. Ignoring antonyms can detract from accuracy when one clearly discerns some meaning from another.

Disregarding Idiomatic and Phrasal Expressions

It is also important to recognise that vocabulary is not just words. English has many idioms and phrasal expressions. If you think about the last time you were given a reading comprehension or sentence correction task, you may have seen expressions like ‘burn the midnight oil,’ ‘call it a day,’ or ‘at odds with.’ You may know the meanings of these expressions by themselves, but if you are unfamiliar with the complete phrase or meaning, you may have difficulty understanding the whole passage.

Learning Rare or Obscure Words

Many students try to increase their vocabulary by learning highly unusual or obscure words. While this is impressive, the focus of the CAT exam will generally not be on obscure vocabulary but on comprehension, reasoning, and practical usage. Learning rare words may lead aspirants to spend less time on more regular words that are much more useful in the exam.

Omitting Roots, Prefixes, and Suffixes

Understanding roots, prefixes, and suffixes helps with figuring out meaning as well as with learning other related words. For example, if one takes the root ‘bene,’ which means good, the words ‘beneficial,’ ‘benevolence,’ or ‘benefactor’ would be quite close relatives that all imply something positive. If one is to learn vocabulary without roots, prefixes, and suffixes, it will take longer and be much less systematic, and your meaning will likely be accurate, although disjointed and tenuously connected to usage.

Not Practicing Consistently

If you do not use the words regularly in your speaking and writing, the vocabulary words that you learn are, for the most part, worthless. A person who is trying to expand their vocabulary can create lists of hundreds of words to memorise, but if the person does not continue to review their memory, along with using the words, they may hardly remember what they studied. If a person forgets what they previously learned, they will also have ‘gaps’ in their knowledge, which means when they read, correct sentences, or work out a parajumble, they will not have the same understanding as they previously had.

Not Reading Broadly

Finally, simply relying on a list of words and not reading anything broadly is a fairly limiting approach. Reading newspapers, magazines, editorials, novels, and stories, etc., are excellent sources of real-world examples of how to use vocabulary words that are examples of real-world context, usage, and meaning. If a student only reads habitually and uses vocabulary words sourced from a different place, the student may be able to define what an individual vocabulary word means, but when the student encounters the vocabulary word being used in a sentence in a reading passage, the student would likely not be able to know what the passage is saying or infer the meaning, usage, or thought process of the authors.

Knowing vocabulary is not just about memorising words; it is also about discussing words, appropriately using words in context, and applying words for practical functions. The errors outlined above are all very common errors made by CAT aspirants that, when corrected, can lead to significant improvements in heading and comprehension accuracy, and further, good expression and successful performance in the VARC component of the CAT 2025 examination. Universities with solid liberal arts programmes can provide significant support in overcoming these obstacles. Liberal arts education stresses critical thinking, analytical reasoning, and communication competencies, which naturally enhance vocabulary and contextual understanding.

Students are exposed to various patterns of language and ideas in classes in literature, philosophy, history, and social sciences that allow them to capture nuanced meanings and use the concepts presented.
