In the previous posts we came to know about some of the basics of prepositions. We also came to know different kinds of prepositions. Now in this topic let us know how to use, where to use prepositions for proper meaning of the sentences. There are 4 golden rules pertaining to the proper usage of prepositions.
Rule1: In situations, the prepositions might be required to be placed at the end of the sentence. In such scenarios, they can be used following ways
a) When the relative pronoun is ‘that’
Example: Here is the book that you have been searching for.

Usage of Prepositions
b) When the preposition governs the relative pronoun.
Example: He is the person whom we are searching for.
This is the baby which we are looking after.
Relative pronouns-whom and which
c) When the relative pronoun is understood.
Example: This is the boy you spoke to.
Those are the goals we aim at.
d) In the case the preposition governs the interrogative pronoun or interrogative verb.
Example: What is she looking at?
What is the name of the person on whom the whole responsibility is laid on?
e) The preposition is used as infinitive and is placed at the end of the sentence.
Example: Don’t you have a pen to write down?
Don’t you have a chair to sit on?
f) When the object governed by the preposition is place first in the sentence.
Example: This I rely on.
She is known all the country over.
This is the point the professor on that day insisted on.
Rule 2: A preposition can be used in the beginning of an interrogative sentence.
Example: From which section are you?
To whom should I submit this?
In which country did this culture originate?
Before how many days did you ever open this book?
Rule 3: There are many words which can be used as both prepositions and adverbs. Some of them are above, about, along, across, before, below, behind, besides, by, down, in, near, off, over, past, round, through, under, up, etc.
Example:
| Preposition | Adverb |
| She was here before six. | She has done this before. |
| She was behind us. | He is long way behind. |
| The station is just round the corner. | Come round and meet me this evening. |
Rule 4: There is a specific list of words with prepositions which require gerunds after them.
Note:
Gerund: a verb form which functions as a noun. It used as –ing in a sentence.
