English Grammar for ESL learners 

Prepositional phrases are set phrases or groups of words introduced by a preposition.

Prepositional phrases usually act just like an adjective or adverb, i.e. they provide more information.
For example, if a girl is 'in tears', 'in' is a preposition and 'tears' is the object of the preposition.
The two words together form a prepositional phrase which gives more information about the girl.
