deadliness
Capacity to kill
Deadliness is the quality of being capable of causing death.
A weapon's deadliness depends on its design and the skill of its user.
The word extends to anything potentially fatal: the deadliness of the virus, the deadliness of the winter storms.
Figuratively, deadliness can describe devastating effectiveness: the deadliness of her wit.
