fatális
The word "fatális" is of Latin origin, derived from the word "fatalis," meaning destined or appointed by fate. It is commonly used in several languages, including Hungarian, to denote something that is deadly, catastrophic, or portends disaster. In a medical context, a fatális condition refers to one that is inevitably leading to death. This can apply to diseases, injuries, or complications arising from either.
Beyond medical usage, "fatális" can describe events that have dire consequences or are marked by misfortune.
