Adjective Clauses
An adjective (or relative) clause is a
dependent clause that functions as an
adjective in a sentence. It modifies nouns,
pronouns, or a whole sentence. It begins with
a relative pronoun. It comes immediately
after the words that it modifies. In some
cases, a prepositional phrase may come in
between.

was held in Uruguay.

Adjective Clauses
Adjective clauses are divided into two types:
1. Restrictive clauses
2. Nonrestrictive clauses
The type of the adjective clause determines the
use of commas. Commas are only used with
nonrestrictive clauses.
Eman Alkatheery

Adjective Clauses
Restrictive clauses (Table 4.2, p. 157)
It explains which people, places, or things:
not everything or everyone. It limits the
noun or pronoun that it modifies to only
what is described in the clause. No
commas are used. The relative pronoun
(that) is only used with restrictive clauses.
Eman Alkatheery

Adjective Clauses
Example:
Men who are not married are called bachelors.
The students who passed the exam will take
the next level.
There is only one museum that is open on
Sundays.
Eman Alkatheery

Adjective Clauses
 Nonrestrictive clauses (Table 4.2, p. 157)
It does not define or limit the noun or pronoun that
it modifies. It only adds more information about the
word it modifies. It does not explain which people
or which things. Nonrestrictive adjective clauses
usually modify proper names, nouns that are
unique, and nouns preceded by demonstratives.

Adjective Clauses
Examples:
Professor Jones, who teaches my biology class,
won a Nobel prize.

Adjective Clauses

Clauses with Multiple meanings
In some cases, a particular clause can be either
restrictive or nonrestrictive. (Table 4.3, P. 157)
It can either identify or give extra information.
The adjective clause type can be identified by:
1. The speaker’s or writer’s point of view
2. Punctuation ( commas)

My sister ,who lives in Jeddah, teaches in a high school.

Part Two
Adjective Clauses:
Replacement of Subjects
Eman Alkatheery

Clauses with who, that , and which
A sentence with an adjective clause can be seen
as a combination of two sentences. The relative
pronouns who, which, and that may replace the
subject of a simple sentence in order to form an
adjective clause (Table 4.4., P. 163)
John is a doctor. + John works hard.
John, who is a doctor, works hard.
Eman Alkatheery

In restrictive clauses, who and that refer to
people, but who is preferred.
Which and that refer to animals and things,
but that is preferred.
In nonrestrictive clauses, only who and
which are used. That is not possible.

preposition in a simple sentence in order to
form an adjective clause.
In formal English, the preposition is
sometimes placed before the relative
pronoun. In this case only whom and which
are used.
Eman Alkatheery

If the preposition is placed at the end of a
restrictive clause, that can also be used, or the
relative pronoun can be omitted. This
construction is frequently used in conversational
English, but it is not preferred in formal written
English.

be used. (table 4.13, p. 181).

Part Five:
Adjective Clauses
to Phrase Reduction
Eman Alkatheery

Adjective Clauses to Phrase Reduction
 Adjective clauses can be reduced to participial
phrases.
 A participial phrase is a phrase that contains a past
participle (eaten) or present participle(eating).
 Participial phrases can be formed from adjective
clauses if the relative pronoun is the subject of the
relative clause.
 The time of the phrase is determined by the verb of
the main clause or the general context.
Eman Alkatheery

Reduction of Adjective Clauses
with Verbs in the Active Voice
 In adjective clauses with verbs in the active voice,
eliminate the connecting word (relative pronoun),
and use the present participle of the main verb.
 The present participle is used to replace the verbs in
variety of tenses.
 To form the negative, use (not) before the present
participle.
 If the adjective clause has commas, the participial
phrase has commas, too. (Table 4.14, p. 186)
Eman Alkatheery

 The Taj Mahal, which sits on the Yamuna River, is
one of the architectural wonders of the world.

Eman Alkatheery

with Verbs in the Passive Voice
 In adjective clauses with verbs in the passive voice,
eliminate the connecting word (relative pronoun) and
(is, was, were, are).
 Use the past participle of the main verb.
 To form the negative, use (not) at the beginning of the
adjective clause.
 If the passive verb is a continuous tense, being +past
participle.
 If the adjective clause has commas, the participial
phrase has commas, too. (Table 4.15, p. 188)

made of white marble.

Practice 2, p. 188
Eman Alkatheery

with Verbs in the Perfect Tense
 Adjective clauses with verbs in the present perfect or
the past perfect may be reduced into in two ways.
1. The verbs (have, has, had) can be changed to (
having) plus the past participle of the main verb.
2. The verbs ( have, has, had) are eliminated, and the
main verb is changed to the present participle.
However, this way does not stress the completion of
the action.
Eman Alkatheery

 With clauses in the passive voice, (having + been +
past participle) ) are used.
 ( Not) for the negative and adverbs are place at the
beginning of the participial phrase.
 Punctuation of participial phrases depends on the
adjective clauses being reduced.
 If the adjective clause is nonrestrictive, then the
participial phrase is punctuated. Otherwise, it does
not. ( Table 4.16, p. 190)

Eman Alkatheery

Placement of Nonrestrictive
Participial Phrases
 Nonrestrictive participial phrases are reduced from
nonrestrictive adjective clauses.
 If the nonrestrictive participial phrase modifies the
subject, it can be placed either before or after the
subject. (Table 4.17, p. 192)
 Occasionally, a nonrestrictive participial phrase is
placed at the end of the sentence only if there is no
confusion about which noun is being described.

Appositives
 Adjective clauses with verb ( to be) can be reduced to
phrases by eliminating the relative pronoun and the
