Grammar explanation

Future continuous

We can use the future continuous (will/won't be + -ing form) to talk about future actions that: 

  • will be in progress at a specific time in the future:

When you come out of school tomorrow, I'll be boarding a plane.
Try to call before 8 o'clock. After that, we'll be watching the match.
You can visit us during the first week of July. I won't be working then.

  • we see as new, different or temporary:

Today we're taking the bus but next week we'll be taking the train.
He'll be staying with his parents for several months while his father is in recovery.
Will you be starting work earlier with your new job?

Future perfect

We use the future perfect simple (will/won't have + past participle) to talk about something that will be completed before a specific time in the future.

The guests are coming at 8 p.m. I'll have finished cooking by then.
On 9 October we'll have been married for 50 years.
Will you have gone to bed when I get back?

We can use phrases like by or by the time (meaning 'at some point before') and in or in a day's time / in two months' time / in five years' time etc. (meaning 'at the end of this period') to give the time period in which the action will be completed.

I won't have written all the reports by next week.
By the time we arrive, the kids will have gone to bed.
I'll have finished in an hour and then we can watch a film.
In three years' time, I'll have graduated from university.

Hey Kirk,
Here mingle refers 'in relationship'. I was in a conversation with my friends, where, they were talking about relationships. Statement was ' being a single is so bore'. And my statement was the same that I mentioned above. Which I found wrong, so I wanted to recheck upon the same.
Thank you in advance


Hello again Suffi sharma,

I'm not familiar with that use of 'mingle', but that could be because it's slang or from another variety of English. If you've seen or heard it used similarly in several other contexts, then it might be acceptable in similar contexts. Unless it's relatively new slang, I wouldn't say most speakers of British or American English would completely understand it, either.

All the best,
The LearnEnglish Team

My question is not relevant of the current page but just wanted to check upon the statement. Please let me know if this is wrong.

'There is no fun being a mingle as well.'


Hello Suffi sharma,

Our main purpose here in the comments is to answer questions about our site or questions that are directly related to it, though we try to help our users with other questions as well. In any case, we ask for your questions to be as specific as possible. What is it about this sentence that you are unsure of? To be honest, I don't understand it, mostly because I don't understand what you mean by 'mingle'.

All the best,
The LearnEnglish Team

Hello Team, Good Morning! When i was asked to be prepared for a meeting next week, is it correct to respond, I will have prepared for the meeting? Please correct me if i am in saying so.

Hello kprakashb,

That's correct. Other ways you might respond would be 'I'll be prepared for the meeting' or 'I'll be ready for the meeting' (the most natural way, in my opinion).

It is hard to be sure which of these is best without knowing the context or your relationship with your colleagues, however.


Best wishes,

"He will be tired because he will have been exercising so hard."

I came across this sentence on some other site and found two members arguing over the correct meaning of this sentence.
One argued the sentence meant "the person will be tired in future because of the exercise he will be doing, the exercise being already completed by the time he feels tired"; implying that the action of exercising will get stopped by then.
The other glued himself to the opinion that "he will be tired because of the exercise that will still be going on at that moment from some definite point of time in past"; implying that the action will be continuing at that moment.

I don't know if I have made my points clear or not but I hope I have done so.
So what I want to ask is which one is the correct explanation of the sentence?
Can anyone please help me through this?

Hello i.leonidas,

We normally don't comment on content from other sources, but since this is quite specific I'll tell you how I see it. The continuous aspect used here (in 'will have been exercising') can refer to different aspects of the action being described, so it's not actually completely clear without the context or more specific language. I'd say that it's more likely for the exercise to have finished at the time of speaking, but it is possible that it's still ongoing.

I hope that makes sense. 

All the best,
