FAQ

How are 'may,' 'might,' and 'must' different from each other?

'May' expresses permission or possibility ('You may leave'), 'might' suggests weaker possibility ('It might rain'), and 'must' signals strong obligation or certainty ('You must finish your work').

When should students use 'may' versus 'might' in their writing?

'May' implies a stronger or more likely possibility, while 'might' suggests something less certain — teaching this distinction helps students choose words that precisely match their intended meaning.

How do modal verbs like 'must' appear in informational writing?

In scientific or procedural writing, 'must' often signals a required step or condition ('The mixture must be heated slowly'), making it an important modal for students to recognize in nonfiction texts.
