Conditional Sentences are also known as Conditional Clauses or If Clauses. They are used to express that the action in the main clause (without if) can only take place if a certain condition (in the clause with if) is fulfilled. There are three types of Conditional Sentences.
Conditional Sentence Type 1
→ It is possible and also very likely that the condition will be fulfilled.
Example: If i find her address, I’ll send her an invitation. (with verb)
If i sick,i will see a doctor (with adj)
Conditional Sentence Type 2
→ It is possible but very unlikely, that the condition will be fulfilled.
Example: If I kicked that ball, I would hit the window. (with Verb)
If i were healty,i would go with you. (with adj)
Conditional Sentence Type 3
→ It is impossible that the condition will be fulfilled because it refers to the past.
Example: If I had said it to her, I would have brought her here. (with verb)
if i had been sleepy,i would have slept. (with adj)
