Degrees of Comparison: Positive, Comparative and Superlative | Class 10 English Grammar

 

Degrees of Comparison: Positive, Comparative and Superlative

[Change the given sentence into positive comparative and superlative degree]

Degrees of Comparison are forms of adjectives that are used to compare the qualities of people, animals, places, things, or ideas.

In English grammar, there are three degrees of comparison:

1. Positive Degree
2. Comparative Degree
3. Superlative Degree

---

1. Positive Degree

The Positive Degree is the basic form of an adjective. It describes a quality without directly showing that one person or thing has more or less of that quality than another.

Examples:

• Riya is tall.
• Rahul is intelligent.
• This flower is beautiful.
• The road is wide.
• My bag is heavy.

Positive Degree in Comparison

The positive degree can also be used to compare two people or things with the structure as...as.

Examples:

• Riya is as tall as Sita.
• Rahul is as intelligent as Amit.
• This book is as interesting as that book.
• My bag is as heavy as yours.

For a negative comparison, we use not as...as or not so...as.

• Riya is not as tall as Sita.
• This road is not as wide as that road.
• My bag is not as heavy as yours.

---

2. Comparative Degree

The Comparative Degree is used to compare two people, animals, places, things, or ideas.

The comparative form is generally followed by than.

Examples:

• Riya is taller than Sita.
• Rahul is stronger than Amit.
• This road is wider than that road.
• Gold is more expensive than silver.
• This book is more interesting than that book.

---

3. Superlative Degree

The Superlative Degree is used when we compare three or more people, animals, places, things, or ideas.

The superlative form is generally used with the.

Examples:

• Riya is the tallest girl in the class.
• Rahul is the strongest boy in the team.
• Mount Everest is the highest mountain in the world.
• This is the most interesting book in the library.
• She is the most intelligent student in the class.

Degrees of Comparison – Basic Examples

Positive	Comparative	Superlative
tall	taller	tallest
short	shorter	shortest
small	smaller	smallest
fast	faster	fastest
strong	stronger	strongest
bright	brighter	brightest
kind	kinder	kindest
young	younger	youngest

---

Rules for Forming Degrees of Comparison

Rule 1: Add -er and -est to Short Adjectives

For many short adjectives, we add -er to form the comparative degree and -est to form the superlative degree.

Positive	Comparative	Superlative
tall	taller	tallest
short	shorter	shortest
fast	faster	fastest
slow	slower	slowest
strong	stronger	strongest

Examples:

• Rohan is taller than Mohan.
• Rohan is the tallest boy in the class.
• My car is faster than yours.
• This is the fastest car in the race.

---

Rule 2: Adjectives Ending in -e

If an adjective ends in -e, add only -r for the comparative and -st for the superlative.

Positive	Comparative	Superlative
large	larger	largest
large	larger	largest
brave	braver	bravest
wise	wiser	wisest
fine	finer	finest

Examples:

• Mumbai is larger than Pune.
• Mumbai is one of the largest cities in India.
• Ravi is wiser than his brother.
• He is the wisest man in the village.

---

Rule 3: Adjectives Ending in Consonant + y

When an adjective ends in a consonant followed by y, change y into i and add -er or -est.

Positive	Comparative	Superlative
happy	happier	happiest
easy	easier	easiest
busy	busier	busiest
heavy	heavier	heaviest
pretty	prettier	prettiest

Examples:

• Riya is happier than before.
• She is the happiest girl in the group.
• This question is easier than the previous one.
• This is the easiest question in the test.

---

Rule 4: Double the Final Consonant

When a short adjective ends in a single consonant preceded by a single vowel, the final consonant is often doubled before adding -er or -est.

Positive	Comparative	Superlative
big	bigger	biggest
hot	hotter	hottest
thin	thinner	thinnest
sad	sadder	saddest
fat	fatter	fattest

Examples:

• Today is hotter than yesterday.
• August is one of the hottest months here.
• This box is bigger than that box.
• This is the biggest box in the room.

---

Rule 5: Use More and Most

Many longer adjectives form their comparative and superlative degrees using more and most.

Positive	Comparative	Superlative
beautiful	more beautiful	most beautiful
important	more important	most important
difficult	more difficult	most difficult
interesting	more interesting	most interesting
expensive	more expensive	most expensive

Examples:

• This flower is more beautiful than that flower.
• She is the most beautiful girl in the competition.
• Mathematics is more difficult than some other subjects for some students.
• This is the most difficult question in the paper.

---

Irregular Degrees of Comparison

Some adjectives do not follow the normal rules. Their comparative and superlative forms are completely different.

Positive	Comparative	Superlative
good	better	best
bad	worse	worst
little	less	least
much	more	most
many	more	most
far	farther/further	farthest/furthest
old	older/elder	oldest/eldest

Examples:

• Rahul is better than Amit at cricket.
• Rahul is the best player on the team.
• Today's weather is worse than yesterday's.
• This is the worst mistake I have made.
• I have more books than my brother.
• She has the most books in the class.

---

Comparison Using as...as

The structure as + positive adjective + as is used to show that two people or things have the same degree of a quality.

Examples:

• Ravi is as tall as Rahul.
• This book is as interesting as that one.
• My car is as expensive as yours.
• She is as intelligent as her sister.

For unequal comparison, we use not as...as.

• Ravi is not as tall as Rahul.
• This book is not as interesting as that one.
• My bag is not as heavy as yours.

---

Comparison Using Than

The comparative degree is generally followed by than.

• Ravi is taller than Amit.
• This road is wider than that road.
• Gold is more valuable than silver.
• English is easier than French for him.

---

Superlative Degree with 'the'

The superlative degree is generally used with the when referring to a particular person or thing that has the highest degree of a quality.

• She is the tallest girl in the class.
• He is the best player in the team.
• This is the most beautiful painting in the gallery.
• Mount Everest is the highest mountain in the world.
