Grammar / Conditional Type 2

Conditional Sentences Type II refer to situations in the present. An action could happen if the present situation were different. I don't really expect the situation to change, however. I just imagine „what would happen if …“

if + Simple Past, main clause with Conditional I (= would + Infinitive)

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

Note: Main clause and / or if clause might be negative. 

Example: If I had a lot of money, I wouldn’t stay here.
