Think about your last month. Did you cut your own hair? Repair your own washing machine? Fix your own teeth? Probably not — you paid or asked someone to do it. English has a special pattern for exactly this: 'I had my hair cut', 'We got the machine repaired.' It means you arranged the service; someone else did the work.

Without this pattern, learners say confusing things. 'I cut my hair yesterday' tells an English speaker that you personally held the scissors. 'I repaired my car' means you opened the engine yourself. If a professional did it for you, you need the causative: 'I had my hair cut', 'I got my car repaired.' One small pattern saves you from sounding like you do every job in town yourself.

The structure is: have (or get) + object + past participle. Look at the order carefully: 'I had my hair cut.' First comes 'had', then the thing ('my hair'), and only then the participle ('cut'). The thing sits in the middle. Compare: 'I cut my hair' (I did it) versus 'I had my hair cut' (a hairdresser did it). The word order is the whole meaning.

'Have' and 'get' both work, and in everyday situations they mean almost the same. 'Get' is a little more informal and can suggest some effort or persuading: 'I finally got the landlord to send someone — I got the heating fixed.' 'Have' is neutral and slightly more formal: 'We have the office cleaned twice a week.' As a beginner rule: use either, keep the order, and you will be understood perfectly.

The pattern moves through tenses just like normal 'have' and 'get'. Present habit: 'She has her nails done every month.' Past: 'We got the roof repaired last spring.' Perfect: 'I've just had my eyes tested.' Future or plan: 'I'm going to get this suit cleaned before the wedding.' Questions and negatives use 'do' in simple tenses: 'How often do you have your car serviced?' 'We didn't get the photos printed.'

Who did the work? Usually you do not say, because the point is the arranged result. If you want to name the professional, add 'by': 'We had the kitchen designed by a local company.' There is also a darker cousin of this pattern for bad events that nobody arranged: 'He had his passport stolen at the airport.' Same shape, but here 'have' means something bad happened to his passport — very useful for travel stories.

Finally, do not confuse this with asking a person directly. 'I had my brother fix the shelf' (have + person + base verb) focuses on the person you asked. 'I had the shelf fixed' (have + thing + participle) focuses on the result. At this level, master the thing-plus-participle version first; it covers haircuts, repairs, deliveries, tests, and almost every paid service.

1. 1. I'm having my eyes tested on Thursday.

   An arranged appointment: having + my eyes + tested.

2. 2. We got the flat painted before we moved in.

   'Got... painted' reports a service; the painters are not mentioned.

3. 3. She has her car serviced twice a year.

   Present simple for a regular arrangement: has + car + serviced.

4. 4. Where did you get this jacket altered?

   Question with 'did... get'; the tailor's shop is the answer.

5. 5. He had a new key made for the front door.

   Order check: had + a new key + made, never 'had made a key' here.

6. 6. We're getting the photos printed for Grandma.

   Continuous 'are getting... printed' for a plan in progress.

7. 7. I haven't had my teeth checked for two years.

   Perfect negative: haven't had + object + participle, common with health.

8. 8. They had the wedding cake delivered to the hotel.

   Arranged delivery: had + the cake + delivered.

9. 9. You should get that cough looked at soon.

   Modal + get + object + participle; 'looked at' keeps its preposition.

10. 10. How much does it cost to have a suit cleaned?

    The pattern after 'to': to have + a suit + cleaned, useful for prices.

11. 11. We had the locks changed after the burglary.

    A classic safety arrangement: had + the locks + changed.

12. 12. She got her ears pierced when she was sixteen.

    'Got... pierced' for a personal service, natural in stories.

13. 13. He had his wallet stolen on the metro.

    The bad-event use: nobody arranged it, but it happened to his wallet.

14. 14. Can I get these documents translated by Friday?

    Service request: get + documents + translated; 'by Friday' is the deadline.

The most common error is describing a service as if you did it yourself, or pointing at the doer with a strange 'by' phrase: 'I cut my hair by someone yesterday.' English does not build the idea that way. Put the thing in the middle and use the participle: 'I had my hair cut yesterday.' If you say 'I cut my hair', native speakers will picture you with scissors in front of the mirror.

The second error is word order. Learners say 'I had cut my hair' or 'We got repaired the car.' Both break the pattern, and the first one even sounds like a different tense. The object must come before the participle: had + my hair + cut, got + the car + repaired. A quick self-check: can you point at the thing between the two verbs? If not, rebuild the sentence.

Third, learners use the base verb instead of the participle: 'I got my phone fix' or 'She had her dress make.' The final verb must be the past participle — fixed, made, cut, cleaned — because the thing receives the action, just like in a passive. Think of it as a mini passive hiding at the end of your sentence.

• Service recipe: have/get + the thing + past participle.
• The thing always sits between the verbs: had my hair cut.
• 'I cut my hair' = you did it. 'I had my hair cut' = a professional did.
• 'Get' is casual, 'have' is neutral — both are correct.
• Name the professional only if it matters: '...designed by a local firm.'
• Bad surprises use the same shape: 'He had his phone stolen.'
