Adjectives – NDA English Notes

In Chapter 4 you studied verbs, the functional centre of every sentence. You learned that verbs have specific grammatical behaviour: types, forms, complementation requirements. This chapter now turns to the words that modify nouns and serve as complements after verbs: adjectives.

Do not think of adjectives simply as “describing words.” In English, adjectives have grammatical roles, and those roles determine which form is correct, where the adjective must be placed, and what structure must follow it. The central principle is this:

★  IMPORTANT An adjective is grammatically correct only when its form, position, function, and complementation match the grammatical role it performs in the sentence.

NDA has tested adjective behaviour in ten confirmed questions across three formats spanning 2010 to 2025. The most consistently tested concept (participial adjectives, the -ed vs -ing distinction) has appeared in four separate questions across three papers, establishing it as the chapter’s signature examination target. A student who understands why adjective forms work the way they do will solve those questions systematically.

2. What Is an Adjective? Types and Positions

An adjective is a word that modifies (describes, qualifies, or limits) a noun or pronoun. In a sentence, it answers the questions: What kind? Which one? How many? English adjectives appear in two positions, and the position changes how the adjective functions.

The Two Positions

Attributive position: the adjective appears directly before the noun it modifies. “The tall soldier crossed the river.” “A specialised surgeon performed the operation.” “Specialised” and “tall” are attributive.

Predicative position: the adjective appears after a linking verb and describes the subject. “The soldier is tall.” “The idea remained secret.” “Tall” and “secret” are predicative: they describe the state of the subject, not a quality placed before the noun.

This distinction matters for the examination. Some NDA errors involve using an adverb where a predicative adjective is required, or using the wrong form of a participial adjective in attributive position. Both are form-matching failures at the level of grammatical role.

Type	What It Does	Examples
Descriptive	Describes a quality or characteristic of the noun	tall, happy, red, cold, ancient
Quantitative	Indicates the quantity of the noun	some, many, few, little, much
Demonstrative	Points to a specific noun	this, that, these, those
Possessive	Indicates ownership	my, your, his, her, our, their
Interrogative	Asks a question about the noun	which, what, whose
Distributive	Refers to each of a group individually	each, every, either, neither
Indefinite	Refers to a noun in a general, non-specific way	any, some, all, both, few, several

3. Participial Adjectives: The Core Concept

This is the most important section of the chapter. Four of the ten NDA adjective questions test participial adjective selection, more than any other adjective concept. The examiner has returned to this concept across three separate papers, including twice in the same sitting (NDA 2021-I), confirming it as both reliable and scalable.

A participial adjective is an adjective derived from a verb. When a verb becomes an adjective, it takes either the -ing form or the -ed form, and the choice between them is not a vocabulary decision. It is a grammatical decision based on the direction of the verb’s effect.

The Cause / Experience Principle

Think about the verb “disappoint.” It involves two participants: something that causes disappointment, and someone who experiences that disappointment. When this verb becomes an adjective, it can describe either participant : and the form tells you which role is being described.

The thing that CAUSES the disappointment →  “disappointing” (the -ing form)

The person who EXPERIENCES the disappointment →  “disappointed” (the -ed form)

★ IMPORTANT Step 1: Identify the subject of the sentence. Step 2: Ask:   Does the subject PRODUCE / CAUSE this feeling in others? → Use -ing   Does the subject EXPERIENCE / RECEIVE this feeling? → Use -ed   If the subject is a THING (result, film, news, experience): it causes the feeling → use -ing. If the subject is a PERSON or living being feeling something: they experience it → use -ed.

The Participial Adjective Master Table

Study the table below. For each verb, learn both directions: the -ing form (cause) and the -ed form (experience).

Verb Base	-ing Form (Cause): Subject produces this feeling	-ed Form (Experience): Subject feels this
disappoint	disappointing : The result was disappointing. (result causes it)	disappointed : I was disappointed. (I feel it)
terrify	terrifying : It was a terrifying experience. (it causes terror)	terrified : They were terrified. (they feel terror)
bore	boring : The lecture was boring. (causes boredom)	bored : The students were bored. (they feel bored)
excite	exciting : The match was exciting. (causes excitement)	excited : The crowd was excited. (they feel it)
confuse	confusing : The instructions were confusing. (causes confusion)	confused : The student was confused. (feels it)
tire	tiring : The journey was tiring. (causes tiredness)	tired : The traveller was tired. (feels it)
interest	interesting : The film was interesting. (causes interest)	interested : I was interested in it. (I feel it)
surprise	surprising : The result was surprising. (causes surprise)	surprised : She was surprised. (she feels it)
amuse	amusing : The story was amusing. (causes amusement)	amused : The audience was amused. (they feel it)
annoy	annoying : His behaviour was annoying. (causes annoyance)	annoyed : She was annoyed. (she feels it)
worry	worrying : The news was worrying. (causes worry)	worried : He was worried. (he feels worry)
frighten	frightening : The noise was frightening. (causes fright)	frightened : The child was frightened. (feels it)

All Four Confirmed NDA PYQs : Analysed

NDA 2017-II : Fill in the Blanks:

“The result of the prolonged discussion was _________.”

Options: (a) disappointment  (b) disappointing  (c) disappointed  (d) to disappoint

Subject: “the result” : a thing, not a person. A result does not FEEL disappointment : it CAUSES it in the people involved.

Step 1: subject = “the result” (thing) → it produces the feeling.  Step 2: cause → use -ing.

Answer: (b) disappointing  [NDA 2017-II]

(a) “disappointment” = a noun, not an adjective : wrong word class.

(c) “disappointed” = experiencer form : but the result is not experiencing anything.

(d) “to disappoint” = infinitive : wrong grammatical function.

NDA 2021-I : Fill in the Blanks (Two Questions, Same Paper):

Q42: “I was _________ with the film; I had expected it to be better.”

Options: (a) disappointed  (b) disappointing  (c) annoying  (d) prejudiced

Answer: (a) disappointed  [NDA 2021-I]

Subject: “I” : a person. I EXPERIENCED the feeling. Experiencer → -ed.

(b) “disappointing” = cause form : “I” would be causing disappointment. Wrong direction.

(c) “annoying” = cause form : same mismatch.

(d) “prejudiced” = biased : wrong meaning.

Q43: “It was a _________ experience. Everybody was shocked.”

Options: (a) terrified  (b) horrified  (c) terrifying  (d) denouncing

Answer: (c) terrifying  [NDA 2021-I]

Subject: “the experience” : a thing. The experience CAUSED terror in everybody. Cause → -ing.

(a) “terrified” = experiencer form : experiences cause terror, they do not feel it.

(b) “horrified” = person experiencing horror : wrong direction.

NDA 2021-I tested participial adjectives TWICE, confirming the examiner treats this as a scalable concept that can generate multiple non-redundant questions.

Extension : Special / Specialised / Especial / Specialist

NDA 2025-II extended the participial adjective concept into a more complex adjective-form question, requiring students to distinguish four formally similar adjectives used in a professional medical context.

Word	Meaning	When to Use
special	Unusual, distinctive, out of the ordinary	For things or events that are out of the ordinary: “a special occasion”
specialised	Trained or adapted for a particular field or task	For professionals or tools with specific training/expertise: “a specialised surgeon”
especial	Formal / literary word for “special” or “particular”	Formal contexts: “of especial significance” : rarely used in modern English
specialist	Used as adjective: relating to or working in a specialism	Before a noun: “specialist knowledge”, “a specialist team”

NDA 2025-II : Fill in the Blanks:

“The intricate operation on the patient required the expertise of a/an _________ surgeon.”

Options: (a) special  (b) especial  (c) specialist  (d) specialised

Answer: (d) specialised  [NDA 2025-II]

The operation is intricate and requires specific training: “specialised” conveys trained expertise.

“Special” = unusual/notable : too vague for specialist medical expertise.

“Especial” = formal/literary : archaic and inappropriate here.

“Specialist” = possible, but “specialised” more specifically implies trained expertise.

Students remember words like “interesting” and “interested” from vocabulary learning but cannot choose between them in sentences because they have not learned the direction of the feeling. NDA changes the subject : person or thing : and tests whether the student can identify who causes and who experiences. That is why this concept appears repeatedly and scales so well.

4. Adjective vs Adverb in Predicative Position

After certain verbs, English requires an adjective, not an adverb. This is one of the most common examination traps at the adjective/adverb boundary. Consider this sentence: “They kept the idea secretly.” Most students accept it immediately : “secretly” sounds natural after “kept.” But it is wrong. The correct form is: “They kept the idea secret.”

Linking Verbs and Quasi-Linking Verbs

A linking verb connects the subject to a description of the subject. The complement after it describes the state of the subject, not how the action is performed. Because we are describing a state, the complement must be an adjective, not an adverb.

A quasi-linking verb (like “keep”, “make”, “render”, “prove”) works similarly: it connects the object to a description of the object’s resultant state. The complement describes what state the object is in, not how the action was done.

“They kept the idea secret.”

→ “keep” acts as quasi-linking here: the idea was maintained in a state of secrecy.

→ “secret” (adjective) describes the STATE of the idea.

→ “secretly” (adverb) would describe HOW they kept it: wrong meaning, wrong class.

NDA 2017-I : Sentence Improvement:

“They kept the idea secretly.”

Underlined: “secretly”  |  Options: (a) secretive  (b) secret  (c) secretively  (d) No improvement

Answer: (b) secret  [NDA 2017-I]

(a) “secretive” = describes a person’s tendency to conceal things : not the state of an idea.

(c) “secretively” = adverb of manner : same error class as “secretly”.

(b) “secret” = adjective describing the state of the idea. Correct.

Verb	Complement Structure	Correct Example	Incorrect Form
seem (linking)	seem + adjective	The task seems easy.	The task seems easily.
appear (linking)	appear + adjective	She appeared calm.	She appeared calmly.
remain (linking)	remain + adjective	She remained calm.	She remained calmly.
become (linking)	become + adjective	The weather became cold.	The weather became coldly.
feel (state)	feel + adjective	The fabric feels soft.	The fabric feels softly.
look (state)	look + adjective	She looks happy.	She looks happily.
keep (quasi-linking)	keep + object + adjective	They kept the idea secret.	They kept the idea secretly.
make (quasi-linking)	make + object + adjective	The news made him happy.	The news made him happily.
render (quasi-linking)	render + object + adjective	Fear rendered him helpless.	Fear rendered him helplessly.
turn (quasi-linking)	turn + adjective	The leaves turned yellow.	The leaves turned yellowly.

The test is straightforward: if the word describes what something IS (its state), use an adjective. If it describes HOW an action was performed (its manner), use an adverb. After linking and quasi-linking verbs, you are always describing a state.

5. Adjective Placement: “Enough” and Position Rules

Where you place an adjective in a sentence is not arbitrary. English has specific placement rules, and violating them produces a grammatically incorrect sentence even when the meaning is clear.

“Enough”: The Postpositive Rule

The word “enough” functions differently depending on what it modifies. When it modifies a noun, “enough” comes before it: “enough time”, “enough money”. When it modifies an adjective, “enough” must come after it: “old enough”, “good enough”. This is invariable.

★ IMPORTANT “Enough” is NEVER a leader when modifying an adjective. It always follows: “old enough”, “good enough”, “rich enough”. “Enough old” is always wrong. “Enough” leads only before nouns: “enough time”, “enough money”.   Correct: Rekha is old enough to get married. Incorrect: Rekha is enough old to get married.  [NDA 2010-I : Error: “enough old”]   Correct: He is rich enough to afford a house. Incorrect: He is enough rich to afford a house.

NDA 2010-I: Spotting Errors:

“Rekha is enough old to get married.”

Error: Part (b) : “enough old”

Correct: “old enough to get married.”  [NDA 2010-I]

“Enough” modifies the adjective “old”: it must follow, not precede.

Students form “enough old” by analogy with “enough time”, where “enough” correctly precedes a noun. The rule-transfer error is precise: “enough” is a determiner before nouns but a post-modifier adverb after adjectives. The two positions are not interchangeable.

Adjective After Indefinite Pronouns

When an adjective modifies an indefinite pronoun (something, anything, nothing, everyone, anyone), the adjective must come after the pronoun, not before it.

Correct: something important   Incorrect: important something

Correct:  nothing special   Incorrect:  special nothing

Correct:  anyone suitable   Incorrect:  suitable anyone

6. Common Adjective Errors: Four Focused Teaching Points

The NDA Spotting Errors questions on adjectives across 2010–2016 targeted four distinct error types. Each represents a different type of grammatical failure and requires its own focused understanding: they are not variations of the same mistake.

Error Type	Incorrect Form (NDA-Tested)	Correct Form	NDA Year
Redundant degree	sufficient enough to support life	sufficient to support life (or: enough to support life)	NDA 2012-II
Confusing pair	distinctive possibility	distinct possibility	NDA 2010-II
Countability error	number of books is less	number of books is fewer	NDA 2014-I
Complementation error	habitual to drive a car	in the habit of driving a car	NDA 2016-II

6.1 : “Sufficient Enough”: The Redundancy Error

“Sufficient” means adequate: precisely the same as “enough” in most contexts. Using them together in “sufficient enough” creates a tautology, a double degree marker that adds no meaning. It is the grammatical equivalent of saying “enough enough”.

Incorrect:  “The oxygen content of Mars is not sufficient enough to support life.”  [NDA 2012-II]

Correct: “The oxygen content of Mars is not sufficient to support life.”

Correct:  “The oxygen content of Mars is not enough to support life.”

Compare: “more than enough”: NOT tautological. “More than” adds a new meaning (exceeding the required amount). “Sufficient enough” simply repeats the same meaning twice.

6.2 : “Distinct” vs “Distinctive”: The Confusing Pair

Both words derive from the same Latin root (“distinguish”) but carry different meanings in formal English.

Distinct  = clearly recognisable; clearly definite; obvious. “A distinct possibility” = a clear, definite possibility.

Distinctive  = characteristically identifying something; uniquely associated with a particular thing or category. “A distinctive accent” = an accent that is uniquely characteristic of a particular person or region.

Incorrect:  “There is a distinctive possibility that he will leave the job.”  [NDA 2010-II]

Correct:  “There is a distinct possibility that he will leave the job.”

“Distinctive possibility” would mean a possibility that characteristically identifies a category. That meaning is incoherent for this sentence. “Distinct possibility” = a clear, definite possibility. Correct.

Substitution test: try “clear” for “distinct” and “characteristic” for “distinctive”. “A clear possibility” makes sense → use “distinct”. “A characteristic possibility” makes no sense → “distinctive” is wrong here.

6.3 : “Less” vs “Fewer”: The Countability Test

“Less” and “fewer” are both comparative forms of degree, but they apply to different noun types. The rule connects directly to the countable/uncountable distinction taught in Chapter 2.

Fewer = with COUNTABLE nouns (things you can count individually: books, people, ideas, cars)

Less = with UNCOUNTABLE nouns (things measured in bulk: water, money, information, time)

Incorrect:  “The number of books in our library is less.”  [NDA 2014-I]

Correct: “The number of books in our library is fewer.”  (books are countable)

Correct: “We need less time.”  → time is uncountable → less

Correct: “We need fewer minutes.”  → minutes are countable → fewer

Correct: “Add less sugar.”  → sugar is uncountable → less

Correct: “Buy fewer bags of sugar.”  → bags are countable → fewer

Informal English uses “less” for everything (“ten items or less” at supermarkets, “less people” in speech). This is widely heard but non-standard. NDA examinations use the formal standard: countable → fewer. Apply the Chapter 2 countability test: can you count the noun individually? Yes → fewer. No → less.

6.4 : “Habitual to”: The Complementation Error

“Habitual” is an adjective that describes a person’s inherent nature, someone who repeatedly does something by tendency: “a habitual liar”, “a habitual early riser”. It describes what a person IS. It does not take a prepositional complement “to + infinitive.”

Students form “habitual to drive” by false analogy with “accustomed to driving” or “used to driving”, both correct prepositional constructions. The analogy fails: “accustomed” is a participial adjective built for prepositional complementation; “habitual” is not.

To describe the specific habit, English requires: “in the habit of” + gerund

Correct:  “He was in the habit of driving at high speed.”

Incorrect:  “My friend was habitual to drive a car at very high speed.”  [NDA 2016-II]

Correct:  “My friend was in the habit of driving a car at very high speed.”

“Habitual to drive”: not a standard English complementation pattern. “In the habit of driving”: the correct idiomatic expression for a specific habit.

7. Supplementary Adjective Concepts

These concepts have not yet appeared in confirmed NDA PYQs but are standard syllabus content for a comprehensive adjectives chapter and plausible future targets.

Elder vs Older / Eldest vs Oldest

“Elder” and “eldest” are used only within family relationships: “my elder brother”, “the eldest daughter”. They cannot be followed by “than”. For general comparisons of age, “older” and “oldest” are used.

Correct:    “My elder sister lives in Delhi.”  (family relationship : elder)

Correct:   “She is older than her classmate.”  (general comparison : older)

Incorrect:   “He is elder than his friend.”  (elder cannot be followed by “than”)

Further vs Farther

“Farther” refers to physical distance. “Further” refers to abstract distance, degree, or additional extent.

Correct:    “Delhi is farther from Jaipur than from Agra.”  (physical distance)

Correct:    “We need further discussion before deciding.”  (additional, abstract)

Correct:    “Without further delay, the session began.”  (no more: abstract)

Absolute Adjectives

Some adjectives are non-gradable: they describe an absolute state that cannot be more or less. “Unique”, “perfect”, “dead”, “infinite”, “complete”, “total” are absolute. You cannot say “more unique” or “most perfect” because uniqueness and perfection are already absolute.

Incorrect:  “This design is more unique.”  (unique is absolute: you cannot be more unique)

Correct:    “This design is unique.”

Incorrect:    “The project is most complete.”  (complete is absolute)

“Worth” as Adjective + Gerund

“Worth” is an adjective that requires a gerund (not an infinitive) as its complement.

Correct:    “This book is worth reading.”  (worth + gerund)

Incorrect:  “This book is worth to read.”  (worth + infinitive: wrong)

Correct:  “The experience is worth having.”

Compound Adjective Hyphenation

When two or more words together modify a noun, they take a hyphen in attributive position. In predicative position (after a linking verb), the hyphen is omitted.

Correct:    “a well-known author”  (attributive: hyphen required)

Correct:    “The author is well known.”  (predicative: no hyphen)

Correct:    “a five-year plan”  (attributive: hyphen)

Correct:    “The plan is five years old.”  (predicative: no hyphen)
