Usage Note
Imperturbable is a formal, literary adjective; in everyday speech speakers prefer tranquilo or sereno. It is invariable for gender — ella es imperturbable, él es imperturbable — and takes regular plural imperturbables. It describes a deeply stable temperament rather than a passing calm, and is often used in journalistic or literary contexts.
Examples
"El piloto permaneció imperturbable durante la tormenta."
