TYPE 1 CONDITIONAL

Form

if + Simple Present, will-Future

Example: If I find her address, I will send her an invitation.

The main clause can also be at the beginning of the sentence. In this case, don't use a comma.

Example: I will send her an invitation if I find her address.

Note: Main clause and / or if clause might be negative. See Simple Present und will-Future on how to form negative sentences.

Example: If I don’t see him this afternoon, I will phone him in the evening.

Use

Conditional Sentences Type I refer to the future. An action in the future will only happen if a certain condition is fulfilled by that time. We don't know for sure whether the condition actually will be fulfilled or not, but the conditions seems rather realistic â€“ so we think it is likely to happen.

In a Type 1 conditional sentence, the tense in the 'if' clause is the simple present, and the tense in the main clause is the simple future.

As in all conditional sentences, the order of the clauses is not fixed. You may have to rearrange the pronouns and adjust punctuation when you change the order of the clauses, but the meaning is identical.

FUNCTION

The type 1 conditional refers to a possible condition and its probable result. These sentences are based on facts, and they are used to make statements about the real world, and about particular situations. We often use such sentences to give warnings. In type 1 conditional sentences, the time is the present or future and the situation is real.

In type 1 conditional sentences, you can also use modals in the main clause instead of the future tense to express the degree of certainty, permission, or a recommendation about the outcome.
