Causative structures without an agent
In these causative structures, the agent is usually not mentioned.
HAVE + object + past participle
This structure is generally used when we talk about professional services provided for a customer. It means that we are not doing something ourselves but arranging for someone to do it for us:
I
had my hair cut
this morning.
(A hairdresser cut my hair.)
I'm going to
have my apartment painted
.
(I'm going to ask someone to paint my apartment.)
Compare:
I
cut my hair
this morning.
(I did it myself.)
I
'm going to paint
my apartment.
(I'm going to do it myself.)
Have + object + past participle is different from have/has + past participle (present perfect tense) and had + past participle (past perfect tense):
I
had
my hair
cut
.
(causative:
have
+ object + past participle)
I
had cut
my hair.
(past perfect tense:
had
+ past participle)
In this structure, have is not an auxiliary but a main verb and can be used in the same way as ordinary verbs:
I
'd like to have
my photo taken.
Could
you
have
this jacket cleaned?
When
are
you
having
the heater installed?
Have
you ever
had
your ears pierced?
Have + object + past participle can also have the non-causative meaning "experience something unpleasant". In this case, the subject of the sentence did not initiate the action:
I
had my bike stolen
.
(My bike was stolen.)
He
had his leg broken
in a car crash.
(His leg was broken in a car crash.)
GET + object + past participle
This structure has the same meaning as have + object + past participle, but get is more informal:
I
got my hair cut
this morning.
Could you
get this jacket cleaned
?
They finally
got the car serviced
.
It can also be used to express accidents or misfortunes happening to someone in the same way as have + object + past participle can:
I
got my bike stolen
.
(My bike was stolen.)
He
got his leg broken
in a car crash.
(His leg was broken in a car crash.)
