A noun always follows a preposition. A is a preposition and its object. A prepositional phrase can be two or three words long, as these examples show: on the roof, in the door, under the bed.
However, prepositional phrases can be much longer, depending on the length of the preposition and number of words that describe the object of the preposition.
- There is a cat on the roof.
- He is fond of children.
- She sat by the fire.
- The lion and the unicorn fought for the crown.
When we use verbs after prepositions, we use , not .
- We are thinking of visiting them. (NOT We are thinking of to visit them.)
- He insisted on being paid at once. (NOT He insisted on to be paid at once.)
- I hate the idea of getting old.
- I am not very good at cooking.
- I look forward to seeing you soon.
- She objected to my entering her room.
