Sentence Completion and Fill in the Correct Word

What this topic is and why it matters

In AFCAT English, Sentence Completion questions give you a sentence with one or more words removed and replaced by a blank. Four options are listed, and exactly one of them completes the sentence so that it reads correctly and makes sense. Fill in the Correct Word is the same idea: you insert the most suitable word into a gap. The two formats are tested together because the underlying skill is identical — reading a sentence closely enough to know what is missing.

This area rewards two things together — vocabulary (knowing word meanings) and grammar sense (knowing how words fit). Because each question is short and self-contained, it is far quicker than comprehension or para-jumbles. A trained candidate clears most of these in twenty to thirty seconds, which is exactly why The Cavalier treats this topic as a guaranteed-marks zone: fast, predictable, and built on rules you can revise in one sitting.

Importantly, the examiner is not testing obscure dictionary words. The options are usually common words used in a precise way, so the difference between a topper and an average scorer is not a bigger word bank but a sharper sense of which word the context demands. Master the method below and you convert guesswork into near-certainty.

The formats you will see

AFCAT mixes a few patterns. Recognising the pattern instantly tells you what clue to hunt for.

• Single blank, vocabulary type: One gap, options are synonyms or near-synonyms. Meaning decides the answer.
• Single blank, grammar type: The gap needs a particular preposition, article, conjunction or verb form.
• Double blank: Two gaps, options come as pairs. Both words must fit; if even one is wrong, reject the pair.
• Connector type: The blank needs a linking word (although, because, therefore, however) that shows the logical relation between two parts.

The 3-step method: clue, predict, match

Use the same routine on every question so it becomes automatic.

1. Find the clue. Read the whole sentence and underline the word or phrase that signals what the blank needs — a contrast word, a cause, an example, or a describing word.
2. Predict in your own word. Before looking at options, guess a simple word that would fit. This stops the options from confusing you.
3. Match and eliminate. Compare your prediction with the four options. Pick the closest; cross out the rest.

Reading context clues

The sentence almost always hides a clue about the missing word. Train your eye to spot these four:

• Contrast clue: Words like but, although, however, yet, despite, whereas tell you the blank is the opposite of something stated. If the first half is positive, the blank turns negative, and vice versa. Example → “He is rich, yet he lives very ___” demands a word like “simply” because “yet” reverses “rich”.
• Cause and effect clue: because, since, so, therefore, as a result, hence tell you the blank continues in the same direction as the cause. “It rained heavily, so the match was ___” points to “cancelled”.
• Definition or restatement clue: Commas, dashes or “that is” often restate the missing word’s meaning right next to the blank, handing you the answer if you read carefully.
• Example clue: such as, for instance, like, including show the blank is a general word that the listed examples illustrate. If the examples are all fruits, the blank is a category word like “produce”.

Most sentences contain at least one of these signals. Locating the signal word first is the single biggest time-saver, because it tells you the direction of the answer before you even read the options.

Using grammar to eliminate options

Even without knowing every meaning, grammar can knock out wrong choices.

• Part of speech: If the blank follows “the” and precedes a verb, it needs a noun, not an adjective.
• Subject–verb agreement: A singular subject needs a singular verb (he goes, not he go).
• Tense consistency: Match the verb form to the rest of the sentence (“Yesterday he went”, not “goes”).
• Prepositions: Fixed pairs decide the answer — good at, afraid of, capable of, depend on, differ from, interested in, superior to, married to, angry with a person but angry at a thing.
• Articles and countability: Uncountable nouns reject “a/an” and the plural “many”; we say much information, not “many informations”.

The smart move is to scan the words immediately before and after the blank. They often dictate the grammatical category of the answer, letting you eliminate two options without even weighing their meanings. Grammar is your fastest filter; meaning is the final judge.

Collocation and tone: choosing between close words

When two options mean almost the same thing, collocation (words that naturally go together) and tone break the tie.

Collocation

Some words simply pair with certain partners: we say heavy rain not “strong rain”, strong tea not “powerful tea”, commit a crime, make a decision, do homework. The natural-sounding partner is usually the answer.

Tone

Positive sentences need positive words; critical sentences need negative words. If the sentence praises someone, a word like diligent fits, while lazy does not, even if both are adjectives. Watch for tone-setting words elsewhere in the sentence — “unfortunately”, “admirably”, “sadly”, “remarkably” — because they quietly tell you whether the blank should carry approval or criticism.

Degree

Some words differ only in strength. “Annoyed”, “angry” and “furious” share a meaning but rise in intensity. Match the strength of the missing word to the rest of the sentence: a small irritation does not justify “furious”, and a major betrayal is understated by “annoyed”.

Confusable words that trap candidates

AFCAT loves pairs that look or sound alike. Learn the difference once and never lose marks again.

• Affect (verb, to influence) vs Effect (noun, the result).
• Accept (to receive) vs Except (other than).
• Principal (head of a school / main) vs Principle (a rule or belief).
• Stationary (not moving) vs Stationery (writing materials).
• Complement (to complete) vs Compliment (to praise).
• Adapt (to adjust) vs Adopt (to take up).
• Eminent (famous, distinguished) vs Imminent (about to happen).
• Loose (not tight) vs Lose (to misplace or be defeated).
• Council (an assembly) vs Counsel (advice or a lawyer).

These pairs appear with striking regularity, and many candidates lose easy marks simply because they never paused to learn the distinction. Spend ten minutes fixing these in memory and you protect a cluster of marks every attempt.

Cracking double-blank questions

Double-blank questions look harder but are often easier, because each blank gives an extra clue to confirm your choice.

1. Solve the blank you are more sure about first.
2. Eliminate every option pair whose word for that blank fails.
3. From the survivors, check the second blank and pick the pair where both words fit.

Often the two blanks are linked by a connector such as “although” or “because”, so the relationship between them gives a free second clue. If the sentence reads “Although he was ___, he behaved ___”, the two missing words must point in opposite directions, which instantly narrows the pairs.

Worked example

Let us apply the clue–predict–match method to a real-style question.

Notice how the contrast word “Although” and the collocation “performance in the field” together pin the answer.

Speed strategy in the exam

AFCAT is a timed paper with negative marking, so manage these questions smartly.

• Attempt in the first pass. Vocabulary you know should be answered immediately.
• One read only. If you have read the sentence twice and still cannot decide, mark it and move on.
• Eliminate to improve odds. If you can cut two options confidently, an educated guess is usually worth it under AFCAT’s marking.
• Build vocabulary daily. Note new words from newspapers with their collocations, not just bare meanings.
• Do not over-think easy items. If your prediction matches an option cleanly, mark it and move on without second-guessing — hesitation is where time leaks away.
• Trust elimination over translation. You rarely need to know every option’s exact meaning; ruling out the clearly wrong ones often leaves a single survivor.

A disciplined first pass through these questions builds early momentum and a small marks cushion, which keeps you calm for the tougher comprehension and grammar items later in the paper.
