It is a widespread claim in the literature that there does not exist an epistemic use of the modal verb mustn�t in English. Instead, the form can�t is said to fill the gap in the system. This paper shows that there is an epistemic use of mustn�t in present-day English, investigates the contexts in which it appears and compares the use of epistemic can�t and mustn�t.
