Future Simple and Future Perfect

The Future Simple tense is often called the "will tense" because we make the Future Simple with the modal auxiliary will.

The structure of the Future Simple tense is:

Subject + will + main verb

For negative sentences in the Future Simple tense, we insert not between the auxiliary verb and main verb:

Subject + will not + main verb

For question sentences, we exchange the subject and auxiliary verb:

Will + Subject + main verb

When we use the Future Simple tense in speaking, we often contract the subject and auxiliary verb: I will, I'll - you will, you'll - he will, he'll...

In negative sentences, we contract with won't, like this: I will not, I won't - you will not, you won't - he will not, he won't...

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?

The future perfect is made with the future simple of 'have' (will have) and the past participle:

[subject + will have + past participle]
