1. Introduction

When you say “this road is long”, you are describing the road. When you say “this road is longer than that one”, you are comparing two roads. When you say “this is the longest road in the city”, you are identifying the extreme among all roads. These three ways of expressing a property (simple description, comparison between two, and extreme within a group) are the three degrees of comparison, and they govern a distinct set of grammar rules that NDA Exam has tested many times.

What makes this chapter unusual is the breadth of its confirmed questions. Seven confirmed NDA questions span seven years and test seven different aspects of the comparison system. Unlike chapters where one dominant error appears repeatedly, Degrees of Comparison is sampled broadly: the examiner tests a different rule in nearly every confirmed paper. This means the complete degree system, not just one rule, must be prepared.

The chapter’s underlying logic is simple and consistent. Every confirmed question reduces to one of three decisions: which degree is required (positive, comparative, or superlative), which structural word accompanies that degree (as, than, to, the), and which form the adjective takes in that degree (formed correctly, irregular, or absolute). A student who understands these three decisions is equipped for any degree comparison question the examiner designs.

2. The Three-Degree System

Every adjective in English can describe a quality in three ways. Understanding what each degree does (what logical relationship it expresses) is more important than memorising its name. The name follows from the meaning.

DegreeWhat It ExpressesStructureExample
PositiveEquality between two things: they are the same in this qualityas + adjective + as“She is as tall as her sister.”
ComparativeDifference between exactly two: one has more or less of the qualityadjective + -er + than  /  more + adjective + than“She is taller than her sister.” / “She is more patient than her sister.”
SuperlativeExtremity within a group of three or more: one has the most or leastthe + adjective + -est  /  the + most + adjective“She is the tallest in the class.” / “She is the most patient in the group.”

3. Formation Rules

Before applying any comparison rule, you need to know how the comparative and superlative forms are built. The choice between the inflectional forms (-er/-est) and the periphrastic forms (more/most) depends on the number of syllables in the adjective and its ending.

Adjective TypeComparative FormSuperlative FormExamples
One-syllable adjectivesadd -eradd -esttall → taller → tallest  /  long → longer → longest  /  big → bigger → biggest (double final consonant)
Two-syllable ending in -ychange -y to -ierchange -y to -iesthappy → happier → happiest  /  pretty → prettier → prettiest
Two-syllable ending in -le, -ow, -eradd -eradd -estgentle → gentler → gentlest  /  narrow → narrower → narrowest
Two-syllable (others)more + adjectivemost + adjectivecareful → more careful → most careful
Three or more syllablesmore + adjectivemost + adjectivebeautiful → more beautiful  /  interesting → most interesting

One spelling rule applies broadly: for one-syllable adjectives ending in a single vowel + single consonant, double the final consonant before -er/-est. “Big → bigger → biggest.” “Thin → thinner → thinnest.” “Hot → hotter → hottest.” This prevents an ambiguous vowel sound.

Never use both the inflectional form and the periphrastic form together. “More taller” and “most tallest” are both wrong. Each doubles the comparison, which makes no logical sense. Use one or the other, not both.

4. Irregular Comparison Forms

Several common adjectives and adverbs do not follow the regular formation rules. Their comparative and superlative forms are entirely different words, descended from different historical roots. These must be memorised as complete three-part sets, not derived by rule.

PositiveComparativeSuperlativeNote
good / wellbetterbestBoth “good” (adjective) and “well” (adverb/adjective) share these forms
bad / illworseworst“Ill” and “bad” both use “worse/worst”
much / manymoremost“Much” for uncountable; “many” for countable: both use “more/most”
littlelessleastUncountable quantity: “little water” → “less water”
farfarther / furtherfarthest / furthest“Farther” for physical distance; “further” for degree or extent
latelater / latterlatest / last“Later” for time; “latter” for second of two items
oldolder / elderoldest / eldest“Elder/eldest” only for family relationships; “older/oldest” for all other uses
nearnearernearest / next“Next” means immediately following in sequence

The “old / older / elder” distinction is worth remembering: “elder” refers only to members of the same family (“my elder sister”, “his elder brother”). For general age comparisons that do not involve family relationships, “older” is always correct. “The elder of the two cities” is wrong; “the older of the two cities” is correct.

5. The Positive Degree: “As…As” Equality

The positive degree does not compare two things as higher or lower than each other. It compares them as equal in a given quality. The structure is “as + adjective + as.”

Correct:  “She is as tall as her sister.”  (they are equal in height)

Correct:  “He spoke as clearly as a native speaker.”  (equal clarity)

Correct:  “The new model is as efficient as the old one.”  (equal efficiency)

The positive degree also forms a rich system of fixed simile expressions, idiomatic comparisons that use the “as…as” structure with a named reference point.

as brave as a lion  ·  as cool as a cucumber  ·  as bright as a button  ·  as white as snow  ·  as sharp as a razor  ·  as strong as an ox  ·  as light as a feather  ·  as blind as a bat  ·  as clear as crystal

6. “As…As” vs “So…As”: Affirmative and Negative Contexts

Both “as…as” and “so…as” express equality in English. But they are not interchangeable in all contexts. The distribution is governed by whether the sentence is affirmative or negative.

“As…as” = standard for AFFIRMATIVE equality comparisons.

“So…as” or “Not as…as” = both acceptable in NEGATIVE comparisons.

Correct:  “He is as brave as a lion.”  affirmative: “as…as” is correct

Incorrect:   “He is so brave as a lion.”  affirmative: “so…as” is archaic/non-standard

Correct:  “He is not so brave as a lion.”  negative: acceptable

Correct:  “He is not as brave as a lion.”  negative: also acceptable

NDA 2016-II: Fill in the Blanks:

“He is as brave as _______ a lion.”

The blank confirms the standard affirmative “as…as” construction.

Correct: “He is as brave as a lion.”  [NDA 2016-II]

In the affirmative: always “as…as.” “So…as” in the affirmative is a literary or archaic usage, not examined standard form.

ContextCorrect FormAlso Acceptable?Example
Affirmative equality“as…as”No: “so…as” is archaic in affirmative“She is as tall as her mother.”
Negative comparison“not as…as”Yes: “not so…as” is equally acceptable“She is not as tall as her mother.”
Negative (alternative)“not so…as”Yes: both forms correct in negative“She is not so tall as her mother.”

7. The Comparative Degree

The comparative degree is used when two things are being compared, and one has more or less of the quality than the other. The standard structure places “than” after the comparative adjective.

Correct:  “This road is longer than that one.”

Correct:  “She is more intelligent than her classmate.”

Correct:  “The first chapter is easier than the second.”

The word “than” is the structural connector of the comparative degree. It introduces the second element of the comparison, the thing being compared against. Without “than”, the comparative is incomplete as a comparison structure.

A common confusion: “than” (comparison) vs “then” (time). These are entirely different words. “She is taller than her sister” (comparison). “She arrived and then sat down” (time). The examiner has confirmed this as a tested distinction in the NDA 2025-II FITB question.

8. The Two-vs-Many Decision Rule: The Chapter’s Keystone

The most important decision in this chapter is not how to form a comparative or superlative. It is knowing which degree to use in a given sentence. The governing rule is the size of the comparison set.

★  IMPORTANT Count how many things are being compared.   Exactly TWO? → Use the COMPARATIVE degree. THREE or more? → Use the SUPERLATIVE degree.   This single rule governs two confirmed NDA questions and every degree selection problem in this chapter.
Comparison SetRequired DegreeSignal WordsConfirmed NDA Instance
Exactly two itemsComparative“of the two”, “between the two”, “of the two options”“the prettier of the two”  [NDA 2013-I ]
Group of three or moreSuperlative“of all”, “in the class”, “in the city”, “among all”“the oldest monument in the city”  [NDA 2024-II]
Two items explicitly namedComparativewhen both are named in the sentence“the better of the two proposals”
Group without explicit countSuperlativewhen the reference is to a full set“the most popular candidate of all”

“Of the Two”: Comparative Required

When a comparison explicitly involves exactly two items and signals this with “of the two”, the comparative degree is mandatory. Using the superlative for a binary comparison is the most foundational error in the chapter. It uses the extreme-in-a-group degree for a context where only two items exist.

NDA 2013-I: Sentence Improvement:

“He is definitely the cleverer among the two.”

Underlined Part: “among”  |  Options: (a) in  (b) of  (c) than  (d) No improvement

Answer: (b) of  [NDA 2013-I]

“The cleverer” is the comparative form, correct for two items. Correct:  The error: “among” is used for three or more members of a group. For exactly two items, “of” is the standard preposition: “the cleverer of the two.”

(a) “in”: wrong preposition for a binary comparison.  (c) “than”: would require rephrasing the entire construction.  (b) “of”. Correct: “He is definitely the cleverer of the two.”

“Of All” and Group Superlatives: Superlative Required

When an item is compared against all others in a defined group (“in the city”, “of all”, “in the class”, “among all candidates”), the superlative is required. The superlative identifies the extreme member of the entire group. A comparative can only compare two; it cannot identify the extreme within a group.

NDA 2024-II: Sentence Completion:

“We saw _________.”

Options: (a) the older of all monuments in the city  (b) the old of all monuments in the city  (c) the oldest monument in the city  (d) an oldest of all monuments in the city

Answer: (c) the oldest monument in the city  [NDA 2024-II]

“In the city” confirms the comparison is against all monuments in the group.

Correct:  “the oldest monument” Correct:  superlative with definite article “the”

Incorrect:   “the older of all monuments” Incorrect:   comparative (“older”) for a group comparison: wrong degree

Incorrect:   “the old of all monuments” Incorrect:   positive degree; cannot identify an extreme: wrong

Incorrect:   “an oldest monument” Incorrect:   superlatives require “the”, not “an”: wrong article

9. The Superlative Degree

The superlative degree identifies the one item in a group that has the most or the least of a quality. It always compares one item against all others in a defined set. Two features of the superlative are non-negotiable.

The superlative ALWAYS requires:

1. The definite article “the” before it: “the oldest”, “the most beautiful.”

2. A group reference that signals “all others”: “in the city”, “of all”, “in the class.”

Without “the” → not standard. With “an” or “a” → always wrong.

Correct:  “She is the tallest student in the class.”

Correct:  “This is the most interesting book I have ever read.”

Correct:  “He is the best player on the team.”

Incorrect:   “She is tallest student in the class.”  missing “the”

Incorrect:   “This is an oldest monument.”  wrong article; superlative needs “the”

10. Degree Structure Equivalence: Three Ways to Say the Same Thing

The same comparative relationship can be expressed using three different degree structures. The meaning is identical; only the grammatical form changes. This is one of the most analytically sophisticated concepts in the chapter, and one that NDA has tested directly.

Consider the statement “The sun is the most beneficial thing in our life.” This uses the superlative. But the same logical claim can be made using the comparative and even the positive degree.

NDA 2019-II: Fill in the Blanks:

Concept tested: what is the positive degree equivalent of a comparative or superlative statement?

“Nothing is as beneficial as the sun.”  [NDA 2019-II]

All three forms express the same comparative relationship:

Degree UsedStructureExample (same meaning in all four)
Superlativethe + most/adjective-est + noun“The sun is the most beneficial thing in our life.”
Comparative (negative)Nothing is more X than…“Nothing is more beneficial than the sun.”
Positive (negative)Nothing is as X as…“Nothing is as beneficial as the sun.”  [NDA 2019-II]
Comparative (inverse positive)X is more… than anything else“The sun is more beneficial than anything else.”

This equivalence is a powerful examination tool. A question may present the superlative form and ask for the equivalent positive or comparative form, or vice versa. Students who understand the logical equivalence can move fluently between all three degree structures.

The underlying logic: “the most X” says X surpasses everything. “Nothing is more X than A” says the same thing from a different angle. “Nothing is as X as A” says A equals or exceeds everything. All three make the same claim about A’s position at the top.

11. “Prefer…To”: Not “Prefer…Than”

The verb “prefer” expresses a preference, a comparative judgement about which of two things is liked more. Because “prefer” involves a comparison, students almost always assume it takes “than”, the standard comparative connector. This assumption is wrong.

“Prefer” is followed by “to” when introducing the less-preferred item. “To” here is a preposition governing the object of comparison, not the comparative conjunction “than.” This makes “prefer…to” a lexically fixed construction that does not follow the general comparative pattern.

Correct:  “I prefer tea to coffee.”

Incorrect:   “I prefer tea than coffee.”

The trap: students reach for “than” by analogy with:

•  “I would rather have tea than coffee.”  (rather…than)

•  “It is better to study than to idle.”  (better…than)

•  “He would sooner leave than argue.”  (sooner…than)

All of these use “than” correctly. “Prefer” is the exception: it uses “to.”

NDA 2014-I: Sentence Improvement:

“He preferred death rather than imprisonment.”

Underlined Part: “rather than”  |  Options: (a) for  (b) to  (c) than  (d) No improvement

Answer: (b) to  [NDA 2014-I]

“Prefer + to” is the correct fixed construction. “Rather than” is redundant alongside “prefer”. Both express preference. Using “rather than” after “prefer” creates a redundant double preference marker.

Correct: “He preferred death to imprisonment.”

(a) “for”: wrong preposition; not part of any standard preference construction.  (c) “than”: closer, but “prefer” does not take “than”; “to” is required.  (b) “to”. Correct: “prefer X to Y.”

ConstructionCorrect ConnectorExample
“prefer”to“I prefer reading to watching television.”
“would rather”than“I would rather read than watch television.”
“would sooner”than“I would sooner leave than apologise.”
“better”than“It is better to be honest than dishonest.”
“compare” (contrast)with“Compare this with the earlier version.”

12. “Too…To” vs “Very…To”

“Too” and “very” are both intensifiers: they amplify the degree of an adjective. But they work in completely different ways, and they cannot substitute for each other in the “intensifier + adjective + to + verb” construction.

“Too” introduces a RESULT that PREVENTS the action from happening.

“Very” intensifies, but carries NO such consequence.

Correct:  “He is too weak to open the door.”  His weakness prevented the opening. The “to” clause expresses the prevented result.

Incorrect:   “He is very weak to open the door.”  “Very weak”: so what? The construction is meaningless without the implication of prevention.

NDA 2014-I: Fill in the Blanks:

“The old man was —— weak to open the door.”

Options: (a) very  (b) far  (c) much  (d) too

Answer: (d) too  [NDA 2014-I]

The “to open the door” clause expresses the prevented result. Only “too” introduces a consequence that prevents an action.

(a) “very weak to open the door”: meaningless; “very” cannot introduce prevented results. 

(b) “far weak”: not a standard intensifier construction with adjectives. 

(c) “much weak”: “much” intensifies comparatives (“much better”), not positive adjectives. 

(d) “too weak to open the door” : weak to such a degree that opening was impossible.

Correct:  “She is too tired to work.”  so tired that she cannot work

Correct:  “The bag is too heavy to carry.”  so heavy that carrying is impossible

Correct:  “He was too shocked to speak.”  so shocked that speaking was impossible

13. “Fewer Than” vs “Less Than”

Both “fewer” and “less” express a smaller quantity. But they apply to different types of nouns, and using the wrong one is a grammar error in standard formal English.

“Fewer” = smaller number of COUNTABLE nouns (things you can count individually).

“Less” = smaller amount of UNCOUNTABLE nouns (things measured as a mass or quantity).

Correct:  “There are fewer than thirty students inside the classroom.”  students = countable

Incorrect:   “There are less than thirty students inside the classroom.”  students = countable: wrong

Correct:  “He drinks less water than before.”  water = uncountable

Incorrect:   “He drinks fewer water than before.”  water = uncountable: wrong

NDA 2025-II: Fill in the Blanks:

“There are _________ thirty students inside the classroom at any time.”

Options: (a) less than  (b) fewer than  (c) less then  (d) fewer then

Answer: (b) fewer than  [NDA 2025-II]

“Students” is a countable noun → “fewer” is required.

(a) “less than”: wrong; “less” is for uncountable nouns.  (c) “less then”. Double error: wrong intensifier + “then” instead of “than”.  (d) “fewer then”: “then” is a time adverb; “than” is the comparative connector.  (b) “fewer than” ✓: correct intensifier for countable noun + correct comparative word.

UseWordNoun TypeExamples
Smaller numberfewerCountable (students, books, people, cars)“Fewer than ten people attended.” / “Fewer mistakes were made.”
Smaller amountlessUncountable (water, money, time, rice)“There is less water in the tank.” / “He has less patience.”
Time / distance / money (treated as singular quantity)lessTreated as a single measure“It took less than an hour.” / “It cost less than fifty rupees.”

14. Absolute Adjectives: Words That Cannot Be Compared

Some adjectives describe qualities that are absolute: complete, total, all-or-nothing. These qualities cannot logically exist in degrees. A thing is either dead or it is not. It is either unique or it is not. It is either perfect or it is not. Because the quality is already complete at its positive form, there is no logical meaning to “more dead” or “the most unique.”

AdjectiveWhy It Cannot Be ComparedWrong FormsCorrect Alternative
uniqueIf something is unique, it is the only one of its kind: there is nothing to compare it to“more unique”, “most unique”, “very unique”“nearly unique”, “almost unique”, “one of a kind”
perfectPerfect means flawless, complete, without deficiency: there are no degrees of perfection“more perfect”, “most perfect”, “very perfect”“nearly perfect”, “almost perfect”
deadDead is an absolute state: there is no degree of being dead“more dead”, “deader”, “very dead”“almost dead”, “nearly dead”
completeComplete means finished, whole: a thing cannot be “more complete”“more complete”, “most complete”“nearly complete”, “almost complete”
infiniteInfinite has no limit by definition: “more infinite” is meaningless“more infinite”, “most infinite”“approaching infinite”, “vast”

Quick Revision

Rule Summary

Rule 1:  Count the comparison set. TWO items → comparative (-er/more). THREE or more → superlative (-est/most).

Rule 2:  “Of the two” → comparative always: “the prettier of the two”, not “the prettiest.”

Rule 3:  “Of all”, “in the city”, “in the class” → superlative always: “the oldest monument.”

Rule 4:  Superlative always requires “the” before it. “An oldest” and “oldest” (without article) are both wrong.

Rule 5:  “Prefer…to”: not “prefer…than.” Prefer is the fixed exception to the comparative “than” pattern.

Rule 6:  “As…as” for affirmative equality. “Not so…as” or “not as…as” for negative: both acceptable in negative.

Rule 7:  “Too + adjective + to + verb” = degree that prevents the action. “Very” carries no such consequence.

Rule 8:  “Fewer than” for countable nouns. “Less than” for uncountable nouns.

Rule 9:  “Than” (comparison) ≠ “then” (time). Never write “fewer then” or “less then.”

Rule 10:  Degree equivalence: The most X = Nothing is more X than = Nothing is as X as. All three express the same meaning.
