What Is The First Conditional?

The first conditional, also known as the “real conditional,” “possible condition,” or “likely future,” is a structure used in English grammar to talk about probable or possible events in the future.

These are future situations that are seen as likely or real by the speaker.

First Conditional Structure

The first conditional consists of two clauses, one with “if” and one main clause.

The structure is as follows:

First ConditionalStructureExample
Affirmative FormIf + present simple, will + base form of verbIf we play truth or dare, I will prepare the questions.
Negative FormIf + present simple, will + not + base form of verbIf we don’t play truth or dare, I won’t need to think of any questions.

In these examples, the “if” clause expresses a condition, i.e., something that must happen first for the other thing to happen. The other clause then expresses a possible result of this condition.

Keep in mind that the order of the clauses does not change the meaning. You could just as easily say, “I will prepare the questions if we play truth or dare.”

When To Use The First Conditional In English

The first conditional in English is used to talk about real and possible situations which might happen in the future.

The first conditional discusses conditions and possible results which are likely or probable, not certain or unlikely. For uncertain or unlikely conditions, we typically use the second or third conditionals.

Here are some scenarios where you might use the first conditional:

PlansIf I pass the IELTS speaking exam, I will celebrate.Used when discussing plans contingent on certain conditions.

Asking Questions Using the First Conditional

The first conditional can also be used to ask questions. Here, you will still have an ‘if’ clause and a main clause. However, in the main clause, the ‘will’ and subject are switched in order to form a question. Here are some examples:

  • If it rains, will you stay at home?
  • If you finish your work early, will you go to the cinema?
  • If I make dinner, will you wash the dishes?

Common Mistakes to Avoid When Using the First Conditional

Common MistakeIncorrect ExampleCorrect ExampleExplanation
Incorrect tense in the ‘if’ clauseIf it will rain, I will stay at home.If it rains, I will stay at home.The ‘if’ clause should always use the present simple tense, not the future tense.
Incorrect word order in questionsIf you see her, you will tell her?If you see her, will you tell her?For questions, the structure should be “Will + subject + base form of the verb.”
Forgetting the comma when the ‘if’ clause comes firstIf it rains we will stay inside.If it rains, we will stay inside.A comma should be used to separate the ‘if’ clause and the main clause when the ‘if’ clause comes before the main clause.
