musth
C2Technical / Zoological
Definition
Meaning
A periodic, highly aggressive, and sexually active state in adult male elephants, characterized by elevated testosterone and secretions from the temporal glands.
In modern usage, it can metaphorically describe a state of irrational fury, uncontrollable aggression, or heightened sexual drive in any male animal (rarely human), but its technical meaning is specific to elephants.

- Do not confuse with the modal verb 'must' (должен).
- The 'h' is silent; pronunciation is /mʌst/, not /mʌsθ/ or /mʊsth/.
- There is no direct one-word Russian equivalent; translate descriptively as 'состояние муш' or 'период гона/агрессии у слонов'.
Common Mistakes
- Spelling it as 'must' (the verb).
- Pronouncing the 'h'.
- Using it to describe human anger in formal writing.
- Confusing it with 'musty' (mouldy smell).
