Type 1 Conditional / First Conditional

Here we use a simple present in the if-clause and a simple future in the result clause.

The Type 1 conditional refers to the present or future time. Here the situation is real and possible. It is used to talk about a possible condition and its probable result.

First conditional Alternate Forms

Future in both clauses

Sometimes we use a future tense in both clauses. This is particularly common in polite requests.

Here will means ‘ is/are willing to’. In more polite requests we can use would.

Going to in result clause

Going to often replaces will in the type 1 conditional. This is done to emphasize a certain result.

Going to can be used in the if-clause to mean ‘intend to’.

Present perfect in if-clause

Sometimes we use a present perfect, instead of a simple present, in the if-clause. This is to put an extra focus on the completion of an action.


Should in if-clause

Should is sometimes used in the if-clause to imply that something is possible, but not very likely.

This use of should in the type 1 conditional is stronger than the type 2 conditional in which an imaginary or unreal situation is presented.


Happen to/ should happen to

We sometimes use happen to or should happen to in If- clauses. It suggests that something is unlikely, but if it happens, something else will happen.

Should happen to has a similar meaning.

Modals in result clauses

We can use modals in result clauses to talk about future possibilities, permission and advice.

Provided (that), as long as

Provided that and as long as can be used instead of if to say that a particular condition must be met in order for something to happen.
