The Future Simple

The future simple is straightforward in its formation and wide in its application.

The affirmative form consists of 'will' followed by the infinitive:

Affirmative Contracted Affirmative
I will meet him laterI'll meet him later
You will comeYou'll come
He will help us laterHe'll help us later
She will be lateShe'll be late
It will rain tomorrowIt'll rain tomorrow
We will get married in SeptemberWe'll get married in September
They will cook dinnerThey'll cook dinner

The contracted form 'll is extremely common and is used almost without exception in speech. 'I'll' sounds considerably more natural than 'I will'.

The negative adds 'not' after 'will'. Note that 'will not' contracts to 'won't':

Negative Contracted Negative
I will not goI won't go
You will not be lateYou won't be late
He will not pass the examHe won't pass the exam
She will not get the jobShe won't get the job
It will not snow tomorrowIt won't snow tomorrow
We will not comeWe won't come
They will not stopThey won't stop

Finally, consider the question form of the future simple.

The 'yes / no' question form is as follows:

Yes/No Questions
Will I go?
Will you come early?
Will he arrive soon?
Will she dance?
Will it be cold?
Will we cook?
Will they leave?

To form a 'wh' question, place the question word at the front:

Wh Questions
Where will I go?
Why will you come early?
What time will he arrive?
Who will she dance with?
When will it be cold?
What will we cook?
When will they leave?

Uses of the future simple

1. The future simple with 'will' predicts the future. It is the default way of referring to future time in English and is chosen whenever no other future form is called for. It covers both established future facts and less certain expectations.

  • The sun will rise at 7am.
  • I think the Conservatives will win the next election.

2. Promises, requests, refusals and offers. This is sometimes termed volitional 'will', since it concerns willingness or unwillingness to act in the future.

  • I'll help you with your homework.
  • Will you give me a hand?
  • I won't go!

3. 'Will' likewise expresses a decision taken at the moment of speaking, typically an offer, a promise, or something the speaker has just resolved to do.

  • A: I'm cold. B: I'll close the window.

4. The future simple with 'will' appears in the first conditional, and in other sentences carrying a conditional sense.

  • If it doesn't rain, we'll go to the park.
  • Let's arrive early. That will give us time to relax.

Shall

1. In British English, 'shall' survives mainly in the forms 'shall I?' and 'shall we?'. These are used to invite an opinion, particularly when making an offer or a suggestion.

  • Shall I open the window? (= Do you want me to open the window?)
  • Where shall we go tonight? (= What's your opinion?)

Be going to

1. 'Be going to' expresses future intentions and plans. The decision has normally been taken before the moment of speaking.

  • A: We've run out of milk. B: I know, I'm going to buy some.

2. 'Be going to' also makes predictions. Either form is often possible, but 'be going to' is preferred when there is visible evidence in the present situation.

  • Look at those boys playing football! They're going to break the window.
  • The sky is getting darker and darker. It's going to rain.
