the basic unit of subject and verb to include a prepositional
phrase. You have now formed an extended unit.
A prepositional phrase must have
both a preposition and an object.
Look for more examples of direct objects and prepositional
phrases in this chapter as well as in Chapters 1, 2, and 3,
so that you will be more familiar with these common ways
to form extended units.
6.7 Some Words Are Both Prepositions and Adverbs
A preposition always has an object.
Example:
Susan walks around the pool.
Preposition Object
around the pool = prepositional phrase
When you include the pool as the object of the preposition
around, you have formed a proper prepositional phrase with
both a preposition and an object.
However, some words can be used as prepositions when they
have an object, but they can also be used as adverbs when they
do not have an object.
Example: Susan walks around.
Adverb
This example illustrates when the word around cannot be
called a preposition, because there is no object of a preposition.
In this case, the word around is used as an adverb instead of
as a preposition. You have already covered adverbs in Chapter 5.
An adverb never has an object.
