Subject + Modal + V1 + Object

You should study.

He may come.

We must obey the rules.

11. MIGHT – Weak Possibility

Might का प्रयोग possibility बताने के लिए किया जाता है, अक्सर जब speaker संभावना को कम निश्चित रूप में प्रस्तुत करता है।

May और Might दोनों possibility व्यक्त कर सकते हैं। वास्तविक usage में certainty का अंतर context पर निर्भर कर सकता है।

12. SHALL – Future / Suggestion
