Introduction to Conditionals

Conditionals express situations and their results. There are four types: zero (general truth), first (real future), second (unreal present), third (unreal past).

Why it matters: Conditionals are essential for discussing possibilities, hypotheticals, and cause-effect relationships.

Main uses:

• Zero: general truths (if + present, present)
• First: real future (if + present, will)
• Second: unreal present (if + past, would)
• Third: unreal past (if + had, would have)
