If you had started earlier, you ______ the train.

• Third conditional:
- Had + past perfect + would/could/might have + Vpp + extension. যেমনঃ
- If you had started earlier, you would not have missed the train.
• Conditional sentence এ Had + Sub + V3 + Ext. এভাবে কোন Sentence শুরু হলে সেটিও Perfect conditional/ 3rd conditional হয়।
- If clause এ যদি (had + V3) হয়, তবে পরবর্তী clause এ would/could/might + have + V3 + extension ব্যবহৃত হয়। যেমনঃ
- Had he known anything, he would have told me.
