Conditionals

Conditional Sentences (also known as Conditional Clauses or If Clauses) are used to express that the action in the main clause (without if) can take place (or not) if a certain condition (in the clause with if) is fulfilled. There are three types of Conditional Sentences.

1^st Conditional

→ It is possible and also probable that the condition will be fulfilled.

Form: if + Simple Present, will (not) + infinitive

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

2^nd Conditional

→ It is possible but less probable that the condition will be fulfilled.

Form: if + Simple Past, would (not) + infinitive

Example: If I found her address, I would send her an invitation.

3^rd Conditional

→ It is about unreal past situations, actions that did not happen.

Form: if + Past Perfect, would + have + Past Participle

Example: If I had found her address, I would have sent her an invitation.
