Possibility & Deduction

These modals form a certainty spectrum. "It must be true" (almost certain), "it might be him" (possible), "she can't be right" (almost impossible). The same verbs that express ability and obligation also express how certain we are, and context tells us which.

must / might / may / could / can't + base verb
