Correct usage of Prepositions(with examples)

     Correct usage of Prepositions

a. Sometimes a necessary preposition is omitted.

Example:
Did she influence you with words or actions?
Did she influence you with words or with actions?

b. 'In' is used with names of countries and large towns; 'at' is more often used when speaking of small towns and villages.

Example:(2 one is correct,1 one is wrong)

1. Globarena is in Jubilee Hills at Hyderabad.
2. Globarena is at Jubilee Hills in Hyderabad.

1. She is at Australia.
2. She is in Australia.

c. 'On' is often used in speaking of things at rest, and 'upon' is used of things in motion.

Example:

1. She sat upon the wall.
2. She sat on the wall.

1. She jumped on the wall.
2. She jumped upon the wall.

     d. 'With' often denotes the instrument, and 'by' denotes the agent.

Example:
Ravana was killed by Rama with an arrow.

e. 'In' before a noun denoting a period of time, means 'at the end of' 'within' means
'before the end of'.

Example:
We shall come back in an hour.
We shall come back within an hour.
f. The use of a preposition at the end of a sentence is awkward and is admissible only when it combines with a preceding intransitive verb to form a compound transitive verb.

Example:
The Guru dislikes being talked about.
Such a failure need not be wondered at.

Note: When the object of the preposition is the relative pronoun 'that', the preposition is always placed at the end.

Example:
This is the book that you asked for.
That is the incident we were wondering about.


Note: The preposition is frequently placed at the end when the object is an interrogative pronoun or a relative pronoun.

Example:
What have you been staring at?
This is the incident (which) I was telling you about.

g. 'In' and 'at' are used in speaking of things at rest; 'to' and 'into' are used in speaking of things in motion.

Example:
She is at school.
She is at the top of the stairs.
She ran to school.
She jumped onto the couch.

h. 'Till' is used for 'time' and 'to' is used for place.

Example:
We were discussing till 10 pm yesterday.
The group of thieves ran to the end of the street.

i. 'Since' is used before a noun or phrase denoting some point of time, and is preceded by a verb in some perfect tense.

Example:
Since the last tennis game my father has been winning continuously.
Since I was a small child, I dreamt of making it big.
