USES OF PREPOSITION

Objective case (of Noun or• Pronoun) is used after Preposition.
For example,

Incorrect- I do not depend on he.
Correct- I do not depend on him.

The Prepositions used after two words must be made clear if these two words are connected by and or or.

For example,

Incorrect- She is conscious and engaged in her work.
Correct- She is conscious of and engaged in her work.

If a Principal Verb is used after about, after, at, before. for, from, in, on. to, that Verb must be in ing (V4) form.

For example,

Incorrect- You prevented me from do it.
Correct- You prevented me from doing it. .

On, in, at, are not used before today, tomorrow, yesterday, the following day, the next day etc.

For example,

Incorrect- He will go there on to-morrow.
Correct- He will go there tomorrow.

No Preposition is used before the word home. At home is a phrase which bears a different meaning.

For example,

Incorrect- Bring a T.V. set at home.
Correct- Bring a T.V. set home.

 After Transitive Verbs, like dis¬cuss, describe, reach, order, tell, demand, attack, resemble, ridicule, etc. we directly use the object and no Preposition is used after the Verb.

For example:

Incorrect- The poet describes about the beauty of naturel in this poem.
Correct- The poet describes the beauty of nature in this poem.

Say/suggest/propose/speak/reply/explain/talk/listen/write is followed by to Preposition if there is a person in the form of object.

For example,

1. Incorrect- He did not reply me.
Correct- He did not reply to me.

2. Incorrect- He did not write to a letter.
Correct- He did not write a letter
