Join Ideas Using an Adjective Clause
An adjective clause is a group of words with a subject and a verb that 
describes a noun. Adjective clauses often begin with the word who, which, 
or that and can be used to combine two sentences into one.
TWO SENTENCES  Lorene owns an art and framing store. She is a good 
friend of mine.
JOINED WITH AN   Lorene, who is a good friend of mine, owns an art 
ADJECTIVE CLAUSE  and framing store.
  To join sentences this way, use who, which, or that to replace the sub-
ject of a sentence that describes a noun that is in the other sentence. Once 
you have made this change, you have an adjective clause that you can 
move so that it follows the noun it describes. The sentence with the idea 
you want to emphasize should become the main clause. The less impor-
tant idea should be in the adjective clause.
TWO SENTENCES  Rosalind is director of human services for the town 
of Marlborough. Marlborough is her hometown.
[The more important idea here is that Rosalind is director of human services. The 
less important idea is that the town is her hometown.]
JOINED WITH AN   Rosalind is director of human services for the town 
ADJECTIVE CLAUSE  of Marlborough, which is her hometown.
 NOTE: If an adjective clause can be taken out of a sentence without 
completely changing the meaning of the sentence, put commas around the 
clause.
Lorene, who is a good friend of mine, owns an art and framing store.
[The phrase who is a good friend of mine adds information about Lorene, but it is 
not essential; the sentence Lorene owns an art and framing store means almost the 
same thing as the sentence in the example.]
  If an adjective clause is essential to the meaning of a sentence, do not 
put commas around it.
The meat was recalled for possible salmonella poisoning. I ate it 
yesterday.
The meat that I ate yesterday was recalled for possible salmonella 
poisoning.
[The clause that I ate yesterday is an essential piece of information. The sentence 
The meat was recalled for possible salmonella poisoning changes signifi cantly with the 
adjective clause that I ate yesterday.]
■ Use who to refer 
to a person, which 
to refer to places or 
things (but not to 
people), and that for 
places or things.
