Dependent clauses in complex sentences function in
different ways: as nouns (nominal clauses), as adjectives (adjectival or
relative clauses) and as adverbs (adverbial clauses). The word beginning a clause
tells what kind of clause it is for example: noun clauses often begin with that, adjectival clauses with who, whom, that, which and whose and adverbial clauses with when, before, after, since, as, if, although etc. For example: I will eat
the food since you cooked it
Noun clauses
These are also known as ‘nominal clauses’. A nominal
clause behaves like a noun phrase for example:
I know your wife
I know that
your wife is a banker
In (1) above, your wife is a noun phrase and the
object of the verb, know while in
(2), know again has an object but it
is not a noun clause, that your wife is
a banker. A noun clause object is most often used after the verbs believe,
think, know, hear, say, claim, report, among many others and it is not
compulsory to put ‘that’ before the clause.
A noun clause is sometimes the subject of a verb and
the sentences may begin with that
for example: That you have always been caring impresses me. Most of the time,
this kind of noun clause comes at the end of the sentence after the main verb
and the subject of the sentence is usually ‘it’ for example: It amazes me ‘that
you are so angry’. The noun clause is said to be ‘in apposition’ to ‘it’
(telling us what the ‘it’ is). Noun
clauses of apposition are also found after words like idea, belief, suggestion,
and fact and tells us what the word… is (Jowitt 43) [2].
Example: The fact that
she greeted you annoyed me. ‘The
fact’ is the subject of the verb, annoyed; ‘that …to you’ is a noun clause in opposition to it.
Another type of noun clause comes after the verb ‘be’
or ‘seem’ or ‘appear’ and it is said to be the complement of the verb. Example:
It seems that she rarely washes her
clothes.
Adjectival clauses
They are also known as relative clauses, introduced by
the words who, whom, which, whose, that. These words are called ‘relative
pronouns’, relating the relative clause with which they begin to the preceding
or surrounding clause. It is also an
adjectival clause because it describes or qualifies a noun phrase in the
preceding clause. Relative pronouns
function in diverse ways for
Example:
The girl who
sits next to John comes from Plateau State.
She came to a narrow bridge which crosses a wider river.
In the first sentence, who is the subject of the verb, sits and in the second, which
is the subject of crosses. We are
expected to use whose only if the
noun phrase before it is a living thing if not we ought to use of which. Example: I spoke to the girl whose bag was stolen.
Relative
clauses could be defining or non-defining.
The difference is that commas are not used in defining relative clauses while
commas are used in non-defining relative clauses. Example:
Defining:
The girl who sits next to John comes from Plateau State. The clause who sits next to John is defining
because it defines the girl and
without it, we would not know who the girl is, to which girl is being referred to. Here, there is no comma after girl.
Non-defining: I hardly listen to Don Moen, whose music
is popular
Here, the clause whose
music is popular does not define Don Moen but tells us more about him so a
comma is used after Don Moen.
Adverbial clauses
They function as adjuncts in sentences. Adjuncts
provide additional information that are important, telling us the place, time,
reason, and manner of an event and so on. According to Jowitt (48), there are
various types of adverbial clauses. They are:
Time: When I
come to Jos, I will see you
Condition: if
you go out, do not come in
Reason or Cause: Since
you don’t like me, I will not call you
Contrast or Concession: Although I have not seen him, I love what I hear about him
Place: I live where
the lady stays
Result: He was so glad that I came
Purpose: I am sending you the money so that you can buy the dress
Manner: He was so scared as if he has seen a Ghost
Degree or Comparison: I appreciate you more than I can say
Comment: As you
know, he is a teacher.
