First conditional: real future possibilities — Foreign languages, 7–10
Learn how to connect a possible condition with its likely result. This lets you make plans, warnings and promises about what may happen next.
If this happens, that may happen
The first conditional joins a possible future event to its likely result. Its usual shape is if plus present simple, then will plus the result: “If it rains, we will stay inside.” The condition is not certain, but the result follows that possibility.
A language for choices ahead
People often need to act before they know exactly what will happen: take an umbrella, charge a phone or bring a coat. The first conditional gives a clear pattern for linking a warning or possibility to an action. It keeps the condition open instead of pretending it is certain.
Planning for rain
The weather may change, so build the sentence in two parts. First name the condition: “If it rains.” Use present simple after if, even though it is about the future. Then add the result with will: “If it rains, we will play indoors.” Together, the sentence gives a plan.
Do not put will after if
It feels logical to say “If it will rain”, because the rain is in the future. English usually marks the future only in the result part, not after if: “If it rains, we will stay home.” The present form there does not mean the rain is happening now; it marks the condition.
Weather, safety and promises
You can use this pattern when making a real plan: “If you finish your work, we will play a game.” It also appears in warnings such as “If you touch the pan, you will burn your hand.” The result should be a genuine possible consequence, not a pretend rule for everything.
