Generally when we compare two things or two similar groups or two qualities we use THAN (not then).
- Ram is better than Shyam.
UNOis better than the League of Nations.
But there are some exceptions to this rule:
In case of adjectives ending with ~ior like Senior, Junior, Inferior, Superior we use TO instead of THAN.
- He is superior to him.
- He is junior to him.
- Tom is senior to me.
- He is inferior to him.
‘Elder’ is used while referring to the members of same family or members of the same caste whereas ‘Older’ is used for comparing the age of any two persons.
- Tom is older to me. (No relation of family)
- He is elder to me. ( Family relation)
Prefer is preceded as well as followed by a Noun or a Noun phrase.
- To die is preferable to beg (Wrong, beg is a verb)
- To die is preferable to begging. (Correct)
While comparing using ‘Prefer” we use TO and not THAN.
We use comparative Adjectives only when we compare two things and it is not used when we have to compare more than two things or groups.
- Thomson is taller than all the college boys. (Wrong)
- Thomson is taller that other boys of his college. (Correct)
Very cannot be used before a comparative degree Adjective though VERY MUCH can be used as an exception.
- I feel very much better today. (Generally much better is used though the above construction is also used)
- It is colder today. (Incorrect, only colder is okay)
If we compare one with thing with all other of its kinds then we use Superlative and not Comparative.
- That is a very interesting book that I have read. (Incorrect)
- That is the most interesting book that I have ever read. (Correct)
When ‘Than’ or ‘As’ is followed by a Third Person Pronoun, the Auxiliary Verb is repeated.
- Tom is as clever as his brother is.
- He is not as tall as his school mates are.
When ‘Than’ or ‘As’ is followed by a First person and Second person Pronoun, Auxiliary verb can be omitted.
- Kuber is more intelligent than you (Are).
Whenever an Adjective refers to a class of people its First form is preceeded by the definite Article ‘The.’
The virtuous, the poor, the old etc.
- This house is better that Mohan. (Incorrect as the house cannot be compared with Mohan)
- This house is better than that of Mohan’s (house.) (Correct)
