Parts of Speech
Composing grammatically correct sentences requires an understanding of the various parts of speech. Here is a breakdown of the major parts of speech:
Noun
A noun is a word that represents a person, place, thing, or idea. Nouns can be classified as common or proper and can be singular or plural.
Example: The pilot (common noun) flew an aircraft (common noun).
Pronoun
Pronouns replace nouns in sentences to avoid repetition. Common pronouns include he, she, it, they, and we.
Example: She is a skilled pilot. She flies aircraft.
Verb
Verbs are action words that show what someone or something is doing.
Example: The pilot (noun) flies (verb) the aircraft (noun).
Adjective
Adjectives modify nouns and provide more information about them. They answer questions like "What kind?" or "Which one?"
Example: The fast (adjective) aircraft (noun) soared through the sky.
Adverb
Adverbs modify verbs, adjectives, or other adverbs. They provide more details about how, when, where, and to what extent an action occurs.
Example: The pilot flew the aircraft extremely (adverb) skillfully (adverb).
Preposition
Prepositions show the relationship between nouns or pronouns and other words in a sentence.
Example: The aircraft flew above (preposition) the clouds.
Conjunction
Conjunctions connect words, phrases, or clauses within a sentence.
Example: The pilot and the co-pilot checked the aircraft before takeoff.
Interjection
Interjections are short, exclamatory words or phrases used to express strong emotions.

Subject-Verb Agreement
For constructing grammatically correct sentences, subject-verb agreement is essential. A sentence's verb and subject must agree in number (singular or plural). Listed below are some reference examples:
Singular subjects require singular verbs.
Example:The pilot flies the aircraft.
Plural subjects require plural verbs.
Example: The pilots fly the aircraft.
Compound subjects (subjects joined by "and") usually require plural verbs.
Example: The pilot and the co-pilot fly the aircraft.
When the subject is collective (a group acting as one unit), a singular verb is used.
Example: The team flies the aircraft.
Tenses
In a sentence, tenses indicate the timing of an action. There are three main tenses in English: past, present, and future, each with a variety of forms. The following table shows the same along with a brief description and example:
Tense | Description | Example |
|---|---|---|
Present | Used for actions happening now or regularly | The pilot flies the aircraft. |
Past | Used for actions that have already happened | The pilot flew the aircraft. |
Future | Used for actions that will happen in the future | The pilot will fly the aircraft. |
Perfect Tenses | Indicate actions that were completed at a specific time or before another action | The pilot has flown the aircraft. |
Continuous/Progressive Tenses | Indicate ongoing or incomplete actions | The pilot is flying the aircraft. |
Perfect Continuous Tenses | Combine perfect and continuous aspects to show an action that started in the past, continued, and is relevant to the present | The pilot has been flying the aircraft for hours. |
Articles
Articles (a, an, the) are used to limit or specify nouns. Understanding when and how to use them is crucial for clear sentence construction. Here are some examples:
"A" and "an" are indefinite articles used before singular nouns.
Example: A pilot flies an aircraft.
"The" is the definite article used before specific nouns.
Example: The pilot flies the aircraft.
Active and Passive Voice
In the active voice, the subject performs the action, while in the passive voice, the subject receives the action. Active voice is usually preferred for its clarity and directness.
Active Voice Example: The pilot flew the aircraft.
Passive Voice Example: The aircraft was flown by the pilot.

Direct speech involves quoting someone's words verbatim, while indirect speech reports what someone said without quoting them directly. When converting direct speech to indirect speech, it is essential to change pronouns, tense, and other elements accordingly.
Direct Speech Example: He said, "I will fly the aircraft".
Indirect Speech Example: He said that he would fly the aircraft.
Sentence Structure
Understanding sentence structure facilitates the construction of grammatically correct and comprehensible sentences. Common sentence structures are listed in the following table:

Complex Sentences | Contain one independent clause and at least one dependent clause | While the pilot flew the aircraft, the co-pilot monitored the instruments. |
Compound-Complex Sentences | Combine two or more independent clauses with at least one dependent clause | The pilot flew the aircraft, and the co-pilot monitored the instruments while the ground crew prepared for landing. |

Gerund Phrases | Begin with a gerund (verb + -ing) and function as nouns. | Flying the aircraft is his passion. |
Sentence Types
When writing, it is helpful to employ a variety of sentence types for different purposes. Having a good understanding of them is beneficial to having effective communication. The following table shows the same along with a brief description and example:

Example: The pilot who flew the aircraft is experienced.
Parallelism
A series of words, phrases, or clauses that have the same grammatical structure as one another are said to have parallelism. It creates balance and clarity in sentences.
Example: The pilot enjoys flying, training, and maintaining aircraft.
Subject-Verb-Object (SVO) Structure
The SVO structure is a fundamental pattern for the construction of sentences in the English language. The sentence contains a subject, a verb, and an object.
Example: The pilot (subject) flew (verb) the aircraft (object).
Common Errors to Avoid
To excel in the AFCAT English section, it is crucial to recognise and avoid common grammatical errors. Some of these errors include:
Subject-verb disagreement: Ensure that the verb matches the subject in number.
Misplaced modifiers: Place modifiers (adjectives or adverbs) near the word they modify.
Run-on sentences: Avoid joining multiple independent clauses without proper punctuation.
Fragmented sentences: Ensure that every sentence has a subject and a verb.
Double negatives: Avoid using two negative words in the same sentence.
Pronoun-antecedent agreement: Make sure pronouns agree in gender and number with their antecedents.
Remember that practice is the key to mastering these rules, so utilise sample questions, practice exams, and grammar drills to reinforce your comprehension. If you put in the time and effort, you should be able to conquer the English portion of the AFCAT exam with ease, bringing you one step closer to realising your dream of serving as an officer in the Indian Air Force.
