Where does must collide?

In the semantics of natural language, must is a modal operator expressing necessity: deontically it marks obligation ("you must leave") and epistemically it marks a strong, evidence-based inference ("it must be raining"). von Fintel and Gillies argue that epistemic must is not weak or hedged but signals a conclusion reached indirectly from evidence rather than direct observation. The referent is a logical-linguistic force over propositions, measured by entailment and acceptability judgments, a different construct entirely from grape pulp.[1]

Musth (spelled with an h, from Urdu/Persian for intoxication) is a recurring physiological condition in mature male elephants marked by greatly elevated testosterone, temporal-gland secretion, urine dribbling, and sharply increased aggression and mating drive. Poole and Moss documented musth in free-ranging African elephants, showing it is a distinct periodic state linked to reproductive competition. The referent is a hormonally driven behavioural phase in an animal; it collides with wine must and the modal verb only as a near-homophone, not in meaning.[2]
