English grammar
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
Real Examples from Native Speakers
"So I think I might ask if they could clearance it more because how is the $5?"

This page combines the textbook rule with real-world English: every example is an unscripted clip from a real native speaker. You're hearing how this grammar point sounds in real life, not in a classroom.
