Example: under the lifeguard chair

Preposition Object of Preposition

In this example, under the lifeguard chair, the preposition
under takes the noun lifeguard chair as the object of the
preposition.

The combination of a preposition and an object is called a
prepositional phrase. Phrases by themselves are only fragments,
or building blocks. They must be combined with other parts to
form a complete sentence or unit.

Let’s connect the phrase around the pool with the noun
Susan and the verb walks to form a complete sentence. When
we add Susan as the subject, we must also include the verb,
since Susan, as the subject, performs the action of the verb.

Example: Building Block

Susan walks around the pool.
