- Must expresses high certainty or a strong logical conclusion.
- Might/May indicates a possibility without strong certainty.
- Could suggests a possible scenario or guess, often less certain than "might" or "may."
Conclusion
Modal verbs like "must," "might," "may," and "could" are invaluable tools in communicating how certain we are about our deductions. Whether discussing present situations or reflecting on past events, these verbs help clarify the degree of certainty behind our assumptions.
