mortal

The word carries a heavy sense of fragility and inevitability. When describing life, it evokes the contrast between the ephemeral nature of humans and the timelessness of gods or nature. In its 'fatal' sense, it describes an injury or blow from which there is no recovery. It feels more absolute and final than 'serious' or 'critical'. When used to describe emotions like fear or enmity, it suggests a level of intensity that consumes the entire person, implying that the conflict or terror is so great it could lead to death.
