We use perfect aspect to look back from a specific time and talk about things up to that time or about things that are important at that time.

We use the present perfect to look back from the present:

I have always enjoyed working in Italy. [and I still do]
She has left home, so she cannot answer the phone.

We use the past perfect to look back from a time in the past:

It was 2006. I had enjoyed working in Italy for the past five years.
She had left home, so she could not answer the phone.

We use will with the perfect to look back from a time in the future:

By next year I will have worked in Italy for 15 years.
She will have left home by 8.30, so she will not be able to answer the phone.

Present perfect

We use the present perfect:

  • for something that started in the past and continues in the present:

They've been married for nearly 50 years.
She has lived in Liverpool all her life.

  • when we are talking about our experience up to the present:

I've seen that film before.
I've played the guitar ever since I was a teenager.
He has written three books and he is working on another one.

  • for something that happened in the past but is important in the present:

I can't get in the house. I've lost my keys.
Teresa isn't at home. I think she has gone shopping.

We normally use the present perfect continuous to emphasise that something is still continuing in the present:

It's been raining for hours.
I'm tired out. I've been working all day.

Past perfect

We use the past perfect:

  • for something that started in the past and continued up to a later time in the past:

When George died, he and Anne had been married for nearly 50 years.
She didn't want to move. She had lived in Liverpool all her life.

  • when we are reporting our experience up to a point in the past:

My eighteenth birthday was the worst day I had ever had.
I was pleased to meet George. I hadn't met him before, even though I had met his wife several times.

  • for something that happened in the past and is important at a later time in the past:

I couldn't get into the house. I had lost my keys.
Teresa wasn't at home. She had gone shopping.

We use the past perfect continuous to show that something started in the past and continued up to a time in the past or was important at that time in the past:

Everything was wet. It had been raining for hours.
He was a wonderful guitarist. He had been playing ever since he was a teenager.

Modals with the perfect

We use will with the perfect to show that something will be complete at or before some time in the future:

In a few years they will have discovered a cure for the common cold.
I can come out tonight. I'll have finished my homework by then.

We use would with the perfect to refer to something that did not happen in the past:

If you had asked me, I would have helped you.
I would have helped you, but you didn't ask me.
You didn't ask me or I would have helped you.

We use other modals with the perfect when we are looking back from a point in time. The point of time may be in the future:

We'll meet again next week. We might have finished the work by then.
I will phone at six o'clock. He should have got home by then.

or the present:

It's getting late. They should have arrived by now.
He's still not here. He must have missed his train.

or the past:

I wasn't feeling well. I must have eaten something bad.
I checked my mobile phone. She could have left a message.

Dear Peter,
Thank you very much for your clear explanation.
I now understand the meaning of 'play' and when to use.
Very best regards,

Hello The LearnEnglish Team,

I once saw the two following sentences in a English grammar book:

1. As our new furniture is going to be delivered on Monday morning I'll have to stay at home to check that it [has not been/was not damaged] during transit.

2. By the time you finish getting ready, we [will have missed] the train!

I thought the actions in square brackets are both mentioned when the spaekers are looking back from future. Then why does only the second sentence use the future perfect form?
Thank you in advanced,
Toan

Hi Toan,

In sentence 1, the time reference for the verb is brackets is the future time when you're staying at home to check the delivery, which is why the present perfect or simple past works there.

In sentence 2, the time reference for the verb is the time that the sentence is spoken, so the future perfect form is correct there.

Does that make sense?

All the best,
Kirk

Sir, Have you eaten something today after you have done the worship ?
Now Could I also use past simple for saying the same thing like this (After you did the worship) ?

Hi SonuKumar,

Thanks for clarifying that. 'have eaten' is not really correct because it clearly refers to a past action that is already finished, since other events have occurred after it (the worship, for example). And if you use the past simple for 'eat', then the present perfect doesn't work in the subordinate clause beginning with 'after'. Also, 'do worship' isn't a collocation in standard English.

In other words, I'd recommend 'Did you eat anything after you worshipped?' In English, worship if often referred to by another word. For example, in a Catholic context, one would say 'after mass'. In a Protestant context, it would be 'after church' or 'after the service'. I've seen some reference to 'after prayer' in Muslim contexts. Something like this would be more natural than 'after your worshipped'.

All the best,

Sir, Thank you for clarifying it. I think, we also can't say or write this sentence using the adverb 'Today', which refers to present, like this- Have you eaten something after you've worshiped today right ?

but Can we write this same sentence using participle like this- after worshipping or having worshiped 'today' have you eaten something ?

Hi SonuKumar,

You can use 'today' and the past simple together if the action is clearly in a finished past time, even if it was earlier today. 'After worshipping today' or 'Having worshipped today' are both grammatically correct, though strange. As I explained in my last comment, since the context implies that the eating is a finished past action, 'have you eaten' is not correct -- you should use the past simple instead. If you omit the part about worship, you could ask 'Have you eaten today?', which is a question about a period of time that hasn't finished yet.

All the best,
Kirk

Sir, Have you had something today after you have done worship or you did worship at 7:30 p.m, a short while ago or in the evening ?

I think in subordinate clause, we can you use either past simple or present perfect, but if you use present perfect, you can't use one of the adverbs or prepositional phrases given above with past simple right ?

Hello SonuKumar,

Could you please write the sentences or phrases that you are asking about inside speech marks ('like this') or in brackets (like this)? That would help us understand your question better.

Also, when you say 'Have you had something', are you referring to food? I don't quite understand what you mean without the context.

Thanks in advance.

All the best,

Hello!
I have 2 questions to you. Sometimes, I dont really understand the difference between perfective aspect and past tenses. For example, what are the differences between those phrases?

It was the best meal I've had all week - vs - It was the best meal I had all that week.
I've got milk - vs - I got the milk.

Secondly, are there some perfect counterparts for the perfect aspect? Some semantic contribution? For phrases like, for example:

I hope to finish soon.
She is very helpful.

I want to find counterparts for "finish" and "is" in sentences above.

Looking forward to your response, it will help me a lot with understanding of grammar!

Best wishes!
