Degrees of Comparison are used when we compare one person or one thing with another.

There are three degrees of comparison:

• Positive degree
• Comparative degree
• Superlative degree.

1. Positive degree– It is used when no comparison is made. It is used to denote the mere existence of some quality.

For ex- George is good boy.

This is a big house.

Zoyais a beautiful girl.

2. Comparative degree– It is used when two things are compared.

For ex- Jack is better than Rahul.

That house is bigger than this house.

Riya is more beautiful than Seema.

• “than” is used to compare two things.

3. Superlative degree– It is used when more thantwo things are compared.

For ex- Harry is the best boy of the class.

This is the biggest house in the city.

Neha is the most beautiful girl.

• We use the article ‘the‘ before the superlative degrees.

1. by addition of ‘-er’ and ‘-est’ to the positive degree

2. by addition of ‘-r’ and ‘-st’ to the positive degree ending in ‘e’

3. When the positive ends in ‘y’ and has a consonant before it, we change ‘y’ into ‘i’ and then add ‘er’ and ‘est’.

4. when the positive degree ends in a consonant with a vowel before it, we double the consonant & then add ‘-er’ and ‘-est’

5.  by addition of ‘-er’ and ‘-est’ to the positive degree when it ends in ‘-y’

6. by placing ‘more’ and ‘most’ before the positive form

Some adjectives do not follow any of the rules explained earlier. They are compared irregularly. Here are the different forms of such adjectives.
