🔼CAUSATIVE
HAVE AND GET🔽
Causative
structures are generally taught as a category of passive voice. These types of
structures are used to talk about a situation where we make someone else give
us a service or do something for us. This focus on the speaker that makes
something do something to another person is the main difference between the
classic passive voice and causative structures. Look at the following example:
➧ My car was
serviced yesterday. (passive voice - we are simply interested in the fact that
the car has been repaired)
➧ I had my car
serviced yesterday. (causative structure - the announcer has ordered the repair
of his car)
Cause
structures can be constructed with the GET or HAVE verbs.

⏩ 1. Causative
structures with GET:
get +
complement + infinitive - means "to make someone or something render some
service". There is a connotation of resistance or difficulty:
➧ Get your father
to help with your homework!
➧ I can not get
the car to start.
In this
construction, the complement is the subject of the infinitive.
get +
complement + past participle - means "to cause something to be done".
The past participle is equivalent to the passive voice:
➧ I need to get
my watch repaired.
➧ I got my photo
taken for the new passport.
In this
construction, the complement is not the subject of the participle, but receives
the action expressed by the participle. That is why we speak of equivalence
with the passive voice.
⏩ 2. Causative
structures with HAVE:
have + complemento
+ infinitive without "to" - its meaning is similar to that of the
structure with get, with the difference that it is used above all in American
English and there is no connotation of resistance:
➧ They had us
take off our shoes in the middle of the airport.
➧ I can see Mr.
Jennings now. Have him come in, please!
➧ I had the
plumber fix the pipes in the kitchen.
Remember that
the complement is the subject of the infinitive.
Observation:
There is also
a variant of this structure with the present participle, which focuses on the
duration of a situation:
➧ They had us
laughing all through the evening.
have +
complement + past participle - its meaning is similar to the structure with
get, with the difference that, in some contexts, it is used to talk about
unpleasant situations:
➧ I had my hair
cut yesterday.
➧ I had my house
broken last summer.
Examples causative have and get:
- She is going to have her hair cut at the new
hairdresser's.
- I need to get someone to fix the leak in the kitchen.
- The school should have someone replace the broken
windows.
- I had my car serviced after the accident.
- She had her purse stolen on the bus yesterday.
- He's 35 but he still gets his family to pay his
bills.
- I need to have my eyes checked.
- He had his flat burgled while he was abroad.
- It took me a long time to get somebody to answer my question.
- I didn't have any money, so I painted my flat myself.
Important:
1. Look at the difference between the following sentences:
➧ I cut my hair. (I've done it myself)
➧ I had / got my hair cut. (another person, probably a professional, has cut my hair)
2. The verbs get and have are not always causative:
➧ I got dressed as quickly as I could.
➧ I got home late at night.
➧ They got married in June.
I had lunch in an Italian restaurant.
