Which future do you mean?
English has no single “future tense.” Instead we choose between several forms — will, be going to, the present continuous, and even the present simple — and the one we pick signals how we see the event: a snap decision, a firm plan, a prediction, or a fixed timetable.
Take the news that a 24-hour walkout is looming over Paris’s airports: some outcomes are firm plans, others are predictions, and a few are still just spontaneous reactions. Choosing the right future form is how you keep them apart.
The four forms at a glance
- will + infinitive — snap decisions, promises, and predictions you simply believe: “I think the strike will go ahead.”
- be going to + infinitive — intentions already decided, and predictions backed by evidence in front of you: “Those queues are going to get worse before midday.”
- present continuous — fixed arrangements with a set time or place: “The crew are pushing back stand 42 at 09:00.”
- present simple — timetabled events that run to a published schedule: “The first relief flight departs at 06:15.”
Watch the meaning, not just the form
The tricky pairs are will versus going to, and going to versus the present continuous. Reach for going to rather than will when a plan is already made or the evidence is visible; reach for the present continuous rather than going to when the arrangement is fixed and diarised, down to the time and the gate. That leaves will for the unplanned — the offer you make on the spot, or the prediction you cannot yet back with evidence.
