Since it is a language, hence, the time comes when we need to write or speak comparing between two things. Therefore, the use of comparison cases plays a vital role to form an intriguing structure.
Comparison is formed:
Subject —–> to —->Subject.
Object —-> to —->Object
Things —-> to —->Things
Animal —-> to —->Animal
Comparison between two persons
- He (subject-1) is taller than I (subject-2) /
me. - He (subject-1) is richer than she (subject-2) /
her.
Confusion
In the above sentences, it was easy to identify the subject and object. But when we form a sentence with you as an object, then it is difficult to recognize because “you” is a subject as well as an object either.
As a student of science, you are far better than he. (here it is easy to understand as “you” came before a verb, so it is a subject)
He(sub-1) is better than you(sub-2).

He likes ice cream(obj-1) more than you(obj-2). (Things to person comparison is not possible)
He likes ice cream more than you do. (sub to sub and person to person is possible)
He(sub-1) is as good as I(sub-2).
I am as good as he.
He as well as she is tired.
You as much as he are aware of the fact.
