It’s accurate to say that almost every sentence has at least a preposition. Prepositions  used in a sentence are commonly placed immediately after a noun, an adjective, or a  verb. Just as common are prepositions coming before a noun phrase. Prepositions are  also used after a direct object. 

After noun

Examples:

  • Throughout their ordeal, the hostages never gave up  hope of  being released alive.
  • She doesn’t seem to have worry about anything in life.
  • What he did had brought shame to his family.
  • She felt anger at his change of holiday plan.
  • Both parties expressed satisfaction with the agreement.

After adjective

Examples:

  • Not being  confident about  their future, they decided to emigrate.
  • He has been  absent from  school for two weeks now.
  • She is  busy with  her make-up.
  • The resort is  famous for  its nightlife.

After verb

Examples:

  • We  laughed at  her funny jokes.
  • Someone knocked the antique vase which fell and smashed to pieces.
  • This little boy dreams of driving a big car one day.
  • She believes in everything that is told to her.
  • He's helping her to choose between the two cars. Â

Preposition follows direct object of transitive verb

Examples:

  • She forgives  him for  going out with the other girl.
  • He added something to my soup.
  • Someone stole something from the church.
  • The stranger robbed him of all his money.

Preposition in front of a prepositional phrase .

The preposition is commonly followed by a noun phrase. Together, they form the  prepositional phrase. In the following examples, the prepositional phrases are shown in  bold. The noun in the prepositional phrase is the object of the preposition.

Examples:

  • I still remember the sun sets in the west .

    (Preposition:  in  / Prepositional phrase:  in the west  / Object of preposition:  west )

  • The multistory building was burnt  to the ground .
  • The mere sight of a mouse will make her jump onto the table .  
  • A flock of ducks waddles along the river bank .
  • To reach the other side, we had to swim against the tide .

Preposition can be at the beginning, in the middle, or at the end of a sentence.

Examples:

  • To  whom
  • For  him
  • That's the cave in which we think there are at least a million of bats.
  • There is a small bald patch on top of my head.
