Essential English Grammar and Vocabulary: Your Study Guide
Introduction
This study guide explains the main ways we talk about the future in English: be going to, present continuous, and will / won’t / shall. You will learn when to use each form, see clear examples, and practise with typical situations.
Definition: Future forms are verb structures we use to talk about plans, intentions, arrangements, predictions, promises, offers and instant decisions about things that will happen later.
Overview of the three main future forms
We use three common structures to talk about different kinds of future meaning:
| Form | Use | Example |
|---|---|---|
| be going to + infinitive | Plans and intentions already decided; predictions when there is evidence | My sister's going to adopt a child. Look at those clouds — it’s going to rain. |
| Present continuous (be + verb-ing) | Fixed future arrangements with time/place already arranged | We’re meeting at 10:00 tomorrow. Jane’s leaving on Friday. |
| will / won’t / shall + infinitive | Instant decisions, promises, offers, predictions, future facts, suggestions (shall with I/we in questions) | I’ll carry that bag. I won’t tell anyone. Shall we eat out tonight? |
Definition: An arrangement is a plan with a fixed time or place (for example, a booked event or a scheduled meeting).
be going to + infinitive
Uses
- Plans and intentions — when someone has already decided to do something.
- Example: My sister’s going to adopt a child. (Not: My sister will adopt a child.)
- Predictions with evidence — when we can see signs that something will happen.
- Example: Look at those black clouds. It’s going to rain.
Notes
- Use be going to rather than will when a decision has already been made.
Present continuous (be + verb-ing)
Uses
- Future arrangements — when the time and place are decided (often booked).
- Example: We’re getting married on October 12th. (Emphasises arrangements like a booked church.)
- Common with travel verbs: go, come, arrive, leave.
- Example: He’s arriving tomorrow and leaving on Thursday.
Comparison with be going to
- Both can express plans and arrangements. Differences:
- be going to: shows a decision has been made (general plan).
- present continuous: emphasises arranged details (time/place booked).
💡 Did you know?Fun fact: Many native speakers use both forms interchangeably for plans, so context often decides which is more natural.
will / won’t / shall + infinitive
Uses
- Instant decisions: choose something at the moment of speaking.
- Example: I’ll have the steak. (Deciding at the table.)
- Promises: assure someone about future behaviour.
- Example: I won’t tell anybody where you are.
- Offers: volunteer help.
- Example: I’ll carry that bag for you.
- Predictions and future facts: things we think will happen or are fixed by calendars.
- Example: You’ll love New York! Next year Christmas Day will be on a Thursday.
- Shall: with I and we in questions for offers/suggestions.
- Example: Shall I help you with your homework? Shall we eat out tonight?
Notes
- Use will/won’t (not present simple) for promises, instant decisions and offers.
- Use shall (not will) in formal or polite questions with I or we.
