Why do we use past participle after "get"? for example


1) get it cleaned up.

2) get it reprogrammed.

3) get him done.


What is the use of "have" here? can we use "have" and " let" interchangebly?

1) have them called in.


2) have them done.


3) let them called in.


What is the meaning of " back out of it".



Thanks

Why do we use past participle after "get"? for example
1) get it cleaned up.
2) get it reprogrammed.
3) get him done.
What is the use of "have" here? can we use "have" and " let" interchangebly?
1) have them called in.

3) let them be called in.
What is the meaning of " back out of it".

(When "have/get" is used in this way it is called a "causative verb." A causative verb removes the cause of action from the subject and places it on somebody or something else.
Example: "He wants to have/get his bike fixed."
He is not going to fix his bike, somebody else is.

The active causative structure of a sentence is: subject + causative verb + agent + infinitive of action verb + object.
Example: Judy had her brother do her homework. Judy got her brother to do her homework.
Judy didn't do her homework, her brother did it.

The passive causative structure of a sentence is: subject + causative verb + object + past participle of action verb.
In the passive form, there is usually no agent. The action verb is in the past participle and the object comes before it.
Example: She had/got her hair bleached.
She didn't bleach her hair, somebody else did.

Imperative mood, active causative structure of a sentence is: causative verb + agent + infinitive of the action verb + object.
Example: Have John fix the faucet. Get John to fix the faucet.

Imperative mood, passive causative structure of a sentenct is: causative verb + object + past participle of action verb.
Example: Have/get it cleaned/repaired).

(There are other causative verbs, such as, let, allow,make, help, insist, suggest, recommend, etc. Some use the infinitive with "to"; some use the infinitive without "to." For further study, visit these websites:

"Back out" means to withdraw.
Examples: The singer backed out of his scheduled appearance at the last minte.
First, they offered to do the job, but they backed out when they saw the difficulties).
