Entschlossen vs. entscheidend
While both entschlossen and entscheidend can translate to the English word "decisive", they serve different functions. Entschlossen refers to a person's determined attitude or will (internal resolve), whereas entscheidend refers to the critical nature or impact of an event (external consequence).
