This could be rewritten, omitting the introductory word there. We could say:
A great many people were present.
The noun people is the subject of the sentence.
Exercise 1
In the following sentences, underscore the complete subject with one line, and the simple subject with two lines, and decide whether the simple subject is a noun, pronoun, participle, infinitive or an adjective used as a noun:
1. A great man is universal and elemental.
2. To love justice was his creed.
3. A more inspiring and noble declaration of faith was never born of human heart.
4. The reading of good books should begin in childhood.
5. Dreaming of great things will not bring us to the goal.
6. The weary seek for rest.
7. To believe in yourself is the first essential.
8. He, speaking and writing constantly for the cause, has given his life to the movement.
9. To remain ignorant is to remain a slave.
10. A foolish consistency is the hobgoblin of little minds.
11. A great soul has simply nothing to do with consistency.
12. To be great is to be misunderstood.
13. Traveling is a fool's paradise.
14. It is not enough to be sincere.
15. We, seeking the truth, have found our own.
16. There are thousands of comrades with us.
THE COMPLETE PREDICATE
425. Look first in the predicate for your verb. It will always be the principal part of your predicate. It may be a verb or a verb phrase, but the first thing in analyzing the complete predicate of the sentence is to find the verb. The verb or verb phrase without any of its modifiers constitutes the simple predicate. If the verb is a complete verb, its only modifiers will be adverbs or adverb phrases. For example:
A splendid statue of Lincoln stands yonder in the park.
In this sentence, stands yonder in the park is the complete predicate. Stands is a complete verb. It requires no object, but it is modified by the adverb yonder and by the adverb phrase in the park.
INCOMPLETE VERBS
426. If the verb in the predicate is an incomplete verb of action, then the object of the verb is also part of the predicate. The complete predicate containing an incomplete verb of action may contain five parts; a verb, a direct object, an indirect object, an adverb and an adverb phrase. As for example:
The tailor gladly made him a coat at that time.
In this sentence, the complete predicate is gladly made him a coat at that time. Made is the verb. It is an incomplete verb of action, and coat is its direct object. Him is the indirect object. Made is also modified by the adverb gladly, and the adverb phrase, at that time.
All of these are not always used, of course, in every predicate; but these are the elements which may occur in the predicate with an incomplete verb.
THE OBJECT OF THE VERB
427. Words used as objects of a verb are practically the same as those which may be used for its subject.
We may have a noun used as the object of the verb. For example:
Hail destroyed the crops.
The banks rob the farmers.
We must educate the children.
Labor produces all wealth.
In these sentences, crops, farmers, children and wealth are nouns used as the object of the verb.
A pronoun may also be used as the object of a verb. For example:
Will you not teach me?
Send them to her.
They have invited us.
The comrades will remember him.
In the above sentences, me, them, us and him are the objects of the verbs, will teach, send, have invited and will remember.
Remember that in pronouns we have a different form for the object form, as, me, her, him, us and them.
428.An infinitive may also be used as the object of a verb, thus:
I like to study.
He asked to go.
I want to learn all that I can.
In this last sentence, the infinitive, to learn, is the direct object of the verb want. The object of the infinitive, to learn, is all that I can. All of this taken together with the verb want, forms the complete predicate, want to learn all that I can.
