Now
we will look inside the Predicate, and assign functions to its constituents.
Recall that the Predicate is everything apart from the Subject. So in David
plays the piano, the Predicate is plays the piano. This Predicate
consists of a verb phrase, and we can divide this into two further elements:
[plays] [the
piano]
In formal terms, we refer to
the verb as the PREDICATOR, because its function is to predicate
or state something about the subject. Notice that Predicator is
a functional term, while verb is a formal term:

FUNCTION

However, since the Predicator
is always realised by a verb, we will continue to use the more
familiar term verb, even when we are discussing functions.
The Direct
Object
In the sentence David plays
the piano, the NP the piano is the constituent which
undergoes the "action" of being played (by David, the Subject). We refer
to this constituent as the DIRECT OBJECT.
Here are some more examples
of Direct Objects:
We bought a
new computer
I used to ride a motorbike
The police interviewed all the witnesses
We can usually identify the
Direct Object by asking who or what was affected by the
Subject. For example:
We bought
a new computer
Q. What
did we buy?
A. A new computer ( = the Direct Object)
The Direct Object generally
comes after the verb, just as the Subject generally comes before it. So
in a declarative sentence, the usual pattern is:
Subject --
Verb -- Direct Object
The following table shows more
examples of this pattern:
Subject
|
Verb
|
Direct Object

The tourists |
visited |
the old cathedral |
She |
sent |
a postcard |
The detectives |
examined |
the scene
of the crime |
Realisations
of the Direct Object
The Direct Object is most often
realised by an NP, as in the examples above. However, this function can
also be realised by a clause. The following table shows examples of clauses
functioning as Direct Objects:

Subjects and
Objects, Active and Passive
A useful way to compare Subjects
and Direct Objects is to observe how they behave in active and passive sentences.
Consider the following active sentence:
Active:
Fire destroyed the palace
Here we have a Subject fire
and a Direct Object the palace.
Now let's convert this into
a passive sentence:
