Grammar Focus

The future real conditional (also called the first conditional) is used to talk about real, possible situations in the future and their likely results. If a certain condition is met, a particular outcome will happen. Unlike hypothetical conditionals, the first conditional describes events that the speaker considers genuinely possible.

  • The if-clause uses the present simple tense, even though we are talking about the future: "If it rains tomorrow..."
  • The main clause uses will + base verb to express the expected result: "...I will stay at home."
  • The if-clause can come first or second in the sentence. When it comes first, use a comma: "If you study, you will pass."
  • When the main clause comes first, no comma is needed: "You will pass if you study."
  • Won't (will not) is used in negative results: "If you don't hurry, you won't catch the bus."
  • Questions are formed by inverting the subject and will in the main clause: "Will you come if I invite you?"
  • This structure is extremely common in everyday English for making predictions, giving warnings, making offers, and discussing plans.

Common Mistakes

Using 'will' in the if-clause

If it will rain, I will stay home.
If it rains, I will stay home.

Tip: The if-clause uses the present simple tense, not 'will'. Save 'will' for the main result clause only.

Using future tense in both clauses

If you will study, you will pass.
If you study, you will pass.

Tip: Even though we mean the future, the condition (if-clause) must use the present simple tense. Never put 'will' after 'if' in this structure.

Forgetting the comma when the if-clause comes first

If you call me I will come.
If you call me, I will come.

Tip: When the if-clause starts the sentence, always separate it from the main clause with a comma. No comma is needed when the main clause comes first.
