Relative Clauses, Appositives, and Participles 
An Overview 
You can use relative clauses, appositives, and participles to expand your sentences. Use the following 
information and chart on the back of this sheet to help you understand what each does and where to 
use them. 
Expanding with Relative Clauses 
A relative clause begins with a relative pronoun—
who, which, that, whose, whom
. Most often, the 
relative clause adds descriptive information about a noun in the sentence. 
Look at the following examples: 
1.
The man, 
who looked old enough to be my grandfather
, looked longingly at the red sports 
car.
2.
The man 
who lives next door
looked longingly at the red sports car. 
3.
The man looked longingly at the red sports car, 
which was a sleek Porsche
.
4.
The man looked longingly at the red sports car 
that belonged to his neighbor
. 
5.
The man, 
whose own car was a battered station wagon
, looked longingly at the red sports 
car.
Expanding with Appositives 
An appositive, like a relative clause, come 
after
a noun. Like the relative clauses, it describes or identifies 
the noun that it follows. That is, it tells us who or what something is. Unlike the relative clause, it doesn’t 
start with a relative pronoun, and it almost always is extra, unnecessary information; thus it is set off 
from the rest of the sentence with commas.
Here are some examples: 
1.
The man, 
a tired old geezer in a blue coat
, looked longingly at the red sports car. 
2.
The man, 
a man I had seen many times before
, looked longingly at the red sports car. 
3.
The man, 
my uncle Louis
, looked longingly at the red sports car. 
4.
The man looked longingly at the red sports car, 
a sleek Porsche
. 
5.
The man looked longingly at the red sports car, 
a car that he would never own
.
Expanding with Participles 
While relative clauses and appositives generally give us extra information about 
who
or 
what
something is, participles are verb forms that give us extra information about what one of the nouns in 
the sentence is 
doing
. Most commonly, they are 
–ing
forms, and they are set off from the core
