Some Transitive Verbs take one object only, but still require some word or words to make the predication complete.
The additional word or words by which the predication is made complete are called the Complement.
1. He put the school (Object) into good order. (Complement)
2. His worries drove him (Object) mad. (Complement)
3. They made him (Object) laugh. (Complement)
There is no sense in saying 'he put the school' 'his worries drove him' and they made him.' Hence each Verb must have a Complement.
Forms of Complement
The Complement may be in seven different forms.
1. A Noun
2. An Adjective
3. A Participle
4. A Preposition with its Object
5. An Infinitive Verb
6. An Adverb
7. A Noun Clause
Example Sentences with the Complements in different forms :
(a) They made him king. (Noun)
(b) The judge set the prisoner free. (Adjective)
(c) They found her still weeping. (Participle)
(d) This plot filled us all with terror. (Preposition with Object)
(e) The judge sentenced the prisoner to be hanged. (Infinitive)
(f) They found the man asleep. (Adverb)
(g) We have made him what he is. (Clause) Omission of The Relative as Object
This occurs in two kinds of sentences.
(a) When the Verb is Transitive…
(b) When the Verb is Intransitive, but followed by a Preposition…
This never occurs, however, when the Relative is used in Continuative sense.
1. The books I bought cost three rupees.
2. The house we occupied has fallen down.
3. The man I engaged has now come.
4. He was not careful about the food he ate.
5. The house we lived in has fallen down.
6. The chairs we sat on need new seats.
7. We have at last got the thing we fought for.
8. I have brought the book you spoke about.
9. They have given away the old-dresses you suggested.

Supply the Relative Pronoun that is understood in each of the above sentences.
Transitive Verbs used Intransitively
There are two ways in which Transitives can become Intransitive.
(a) When the Verb is used in such a general sense that no object or objects are thought of in using it.
1. Men eat to maintain life.
2. A new-born child sees. But a kitten is born blind.
(b) When the Reflexive Pronoun is omitted…
1. He drew (himself) near me. Move (yourself) forward.
