Modal Verbs
Modals express different degrees of certainty. From most to least certain: must (very sure — deduction) → should/ought to (expected) → may/might/could (possible — 50% or less). "She must be at home — her lights are on." "It might rain later." Never use "must" for future certainty — use "will" instead.
