Grammar Focus

Imagining a different past — and its consequences.

Third Conditional

An imaginary past situation and its imaginary past result. Neither the condition nor the result actually happened.

if If + past perfect, would have + past participle — "If I'd followed through, I would have made it."

− If + past perfect, wouldn't have + past participle — "If I'd known, I wouldn't have missed out."

Mixed Conditionals

A past condition with a present result, or a present condition about a past situation.

past→now If + past perfect, would + base verb — "If I'd made different choices, I wouldn't be where I am."

now→past If + past simple, would have + past participle — "If I were braver, I would have spoken up."
