To begin with, in the first place, you need to understand what an adjective is. Look at the following example:
Example:It is a beautiful day.
Here, the noun ‘day’ is qualified using the word ‘beautiful’. Hence, beautiful is the adjective in the sentence. Now, degrees of comparison can come into picture only when there are more than or equal to two things available. So, adjectives are compared on the same platform. There are three degrees of comparison of adjectives:
Have a look at the following sentence:
John is the tallest boy in the class.
Here, the word ‘tallest’ shows that John is the only boy in the class who is the tallest. Hence, this is a superlative degree, where the adjective has a suffix ‘est’, and is always accompanied by the word ‘the’. The same sentence can be written in two more ways:
No other boy in the class is as tall as John.
John is taller than any other boy in the class.
In the first sentence here, the word ‘tall’ is used instead of ‘tallest’ but it conveys the same meaning as that of the first sentence. Hence, this is called the positive degree which is always accompanied by the words ‘no other’. Similarly, in the next sentence, the word ‘taller’ is used instead of ‘tall’ and ‘tallest’, but it conveys the same meaning. This is called the comparative degree which is always accompanied by the words ‘any other’. Hence, any adjective can have 3 degrees. Following are some of the examples you can refer to for better understanding.
