Four types
Type 0: always true: If you heat ice, it melts. · Type 1: real, possible: If it rains tomorrow, we will stay home. · Type 2: imaginary (now): If I had a dragon, I would fly to school. · Type 3: imaginary (past): If we had left earlier, we would have caught the bus.
Real or imaginary?
Type 0: it happens every time (science, rules).
Example: If you heat ice, it melts.

Color-coded examples
The Turkish ending -se / -sa = if at the start in English.
Example: If it rains tomorrow, we will stay home.
Example: If you mix blue and yellow, you get green.
Which half first? unless
When the if half comes first, use a comma.
Example: If you need help, call me.
Example: Call me if you need help.
Tip
We usually don't put will / would in the if half: If it rains, we will stay home. (“If it will rain” is wrong.) The will / would in the result half shows the type.
