Three forms, three jobs
English has three common ways to talk about the future: will, going to and the present continuous. Many learners think they are the same, and sometimes they are close. But each one has a main job, and choosing the right one makes you sound natural.
The best question to ask is not what the rule is, but what your situation is. Did you decide just now? Did you plan it before? Did you arrange it with someone else? Your answer points to the right form. This article gives you a simple guide, a choice chart, common mistakes and a few steps to follow.
Will: a decision now, an opinion, an offer, a promise
Use will + base verb when you decide at the moment of speaking, give an opinion about the future, offer help, or make a promise.
- Decision now: The phone is ringing. I’ll answer it.
- Opinion or guess: I think it will be hot tomorrow.
- Offer: Your bag looks heavy. I’ll carry it.
- Promise: I won’t tell anyone your secret.
Will does not change with the subject: I will, she will, they will. In speech we usually say I’ll, she’ll, we’ll, and the negative is won’t.
Going to: an earlier plan or a prediction from evidence
Use be going to + base verb in two main cases.
First, a plan or intention that you made before you speak.
- I’m going to study medicine next year.
- We’re going to paint the kitchen this weekend.
Second, a prediction based on something you can see now.
- Look at those black clouds. It’s going to rain.
- Be careful! You’re going to fall.
Remember that be changes with the subject: I am going to, he is going to, they are going to. In fast speech you may hear gonna, but write going to in careful writing.
Present continuous: a fixed arrangement
Use am/is/are + verb-ing for the future when something is already arranged, often with another person, and usually with a time.
- I’m meeting Sara at six.
- They’re flying to Cairo on Friday.
- We’re having dinner with my parents tonight.
The idea is that you booked it, agreed on it or set the time. The listener hears that it is almost certain. In many sentences going to also works with little change in meaning: I’m meeting Sara at six and I’m going to meet Sara at six are both fine.
The choice chart
| Your situation | Form | Example |
|---|---|---|
| You decide now | will | I’ll take the blue one. |
| Personal opinion or guess | will | I think she will pass. |
| Offer or promise | will | I’ll help you. I’ll call you later. |
| Plan made earlier | going to | I’m going to learn English this year. |
| Prediction from evidence | going to | He’s running fast. He’s going to win. |
| Fixed arrangement | present continuous | I’m seeing the dentist at four. |
If you cannot choose between going to and the present continuous for a near-future plan, going to is usually the safe choice.
Common mistakes Arabic speakers make
| Mistake | Correct | Why |
|---|---|---|
| I will to travel tomorrow. | I will travel tomorrow. | No to after will. |
| She will goes to school. | She will go to school. | No s after will. |
| I’m going to travelling. | I’m going to travel. | Base verb after going to. |
| I going to buy a car. | I’m going to buy a car. | You need am, is or are. |
| If it will rain, I’ll stay home. | If it rains, I’ll stay home. | Use the present simple after if in a normal conditional. |
| Look at the sky! It will rain. | Look at the sky! It’s going to rain. | You can see evidence, so use going to. |
Another common problem: someone asks about your plans and you answer I’ll visit my uncle tomorrow. It is better to say I’m going to visit my uncle tomorrow, because will sounds as if you just decided.
Steps for choosing the right form
- Ask: did I decide just now, while speaking? If yes, use will.
- Am I giving an opinion with words like I think, I’m sure or probably? Use will.
- Can I see clear evidence now? Use going to.
- Was the plan already in my mind? Use going to.
- Is there a booking, appointment or agreement with someone? Use the present continuous with a time.
Try the steps in a restaurant. You decide at the table: I’ll have the soup, please. Later you tell a friend your intention: I’m going to eat there again. And if you booked a table: We’re eating there at eight.
Short dialogues to study
Dialogue one:
A: What are you doing this weekend?
B: I’m going to visit my grandparents. We’re having lunch at their house on Saturday.
Here we have a plan (going to) and a fixed arrangement (present continuous).
Dialogue two:
A: I can’t open this jar.
B: Give it to me. I’ll open it.
This is an offer and a quick decision, so will is right.
Dialogue three:
A: Do you think the team will win?
B: Yes, I think they will. They’re playing very well.
The speaker asks for an opinion, so will appears in both the question and the answer.
British and American notes
In British English you may hear Shall I open the window? as an offer. American speakers more often say Should I open the window? or Do you want me to open the window?. Also, British English writes travelling and American English writes traveling. Both are understood everywhere.
Quick review
- will: a decision now, an opinion, an offer, a promise.
- going to: an earlier plan, or a prediction from evidence.
- present continuous: a fixed arrangement or appointment.
- After will and going to, use the base verb.
- After if, use the present simple, not will, in a normal conditional.
Each day, write three sentences about tomorrow using one form at a time. Soon the choice will feel automatic.
