WORKSHEET, CHS. 4 AND 9
DISTINGUISHING AMONG WHO, THAT, AND WHICH
Careful writers and speakers distinguish among the relative pronouns who, that, and which.
WHO is used to refer to persons. It may introduce essential or nonessential clauses.
Example: Anyone who can build a website is in demand. (The relative clause who can build a website is
essential. Without this clause, the sentence says that anyone is in demand. However, only one who can
build a website is in demand.)
Example: Kevin Lee, who is an excellent Web designer, created our site. (The relative clause who is an
excellent Web designer is nonessential. It describes but does not limit the main clause. The main clause
can stand alone without the added information. Hint: When individuals are named, information added in
who clauses is usually nonessential. Notice that commas set off nonessential clauses.)
THAT refers to animals or things and should be used to introduce essential clauses.
Example: The website that Kevin created attracted many visitors. (The relative clause that Kevin created
is essential. What website attracted many visitors? Only the website that Kevin created attracted the
visitors. Don’t use the relative pronoun which to introduce essential clauses.)
WHICH refers to animals or things and introduces a nonessential clause.
Example: The Sony website, which was totally redesigned by Kevin Lee, is much improved. (The relative
pronoun clause is intended to be nonessential. Because it merely adds extra information, it is set off by
commas.
The tricky part is deciding whether a clause is nonessential. Nonessential clauses contain information that
the reader does not need to know; the main clause is understandable without this extra information. In
some cases, only the writer knows whether the clause is intended to be essential or nonessential. If a
clause is intended to be nonessential, it should be set off from the rest of the sentence by commas.
Essential Clauses – Circle the correct pronoun.
1 Anyone (who, that, which) has a computer can create a website.
2. A company (who, that, which) is located inside the city is more likely to succeed.
3. The car (who, that, which) was without proper license plates was ticketed.
Nonessential Clauses – Circle the correct pronoun.
4. Levi-Strauss, (who, that, which) had a huge hit with its 501 jeans, is now losing market share.
5. We hired Bill Stevens, (who, that, which) came highly recommended, to join the team.
6. The IRS, (who, that, which) audits only 2 percent of all income tax returns, is choked with paperwork.
Answers: 1. who 2. that 3. that 4. which 5. who 6. which
