Mixed Conditionals and Hypotheticals

FIRST CONDITIONAL

The first conditional is used to talk about future events that are likely to happen, as long as a certain condition is met. It expresses real or possible situations, unlike other conditionals that may describe hypothetical or unlikely outcomes. In the first conditional, the “if” clause states the condition, while the main clause describes the result, which is expected to occur if the condition is fulfilled.

Structure (Formula):

  • If + Present Simple, will + base form verb.

It deals with possible future events and highlights cause-and-effect relationships between the condition and the result. The result is probable, but it is dependent on whether the condition in the “if” clause is met.
